Application Objective EMI Testing authorities at Patuxent River Naval Air Systems Command were seeking a unique tension load monitoring solution for their EMI Pulsar Staging System. The Pulsar System is used to test the effects of lightning on electronic controlled military equipment, including aircraft and ground vehicles. The Pulsar System is staged overhead on 20 horizontal suspension cables between two vertical poles, supported and stabilized by 24 vertical support cables. Prior to each Pulsar firing sequence, it is critical that the tension value in each suspension and support cable is confirmed and maintained. In summary, 44 individual suspension and support cables require independent and collective tension monitoring with wireless and portable means to view and process data.
Solution To minimize modification to existing suspension and support cable runs, MSI designed custom clevis load pin sensors that integrated with existing cable interfaces. To effectively and efficiently process output from 44 independent load sensors, the full range of input/output design capabilities of the MSI-9000 CellScaleTM was utilized. Each sensor is individually channeled through a series of MSI-9000 units for processing and wireless broadcast. To minimize the number and length of signal cable runs, the MSI-9008 Multiplexer was used to junction multiple sensor inputs and one output to the MSI-9000. Independent RF communication networks were established in the system configuration to maintain distinction between the staging suspension and support cable sensors. 2.4 GHz RF networks were used to broadcast output from each suspension cable sensor wirelessly to MSI-9750A portable indicators. A unique channel number for independent recognition

A scrap metals processing company sought MSI’s expertise to design and manufacture an integrated solution for their scrap weighing and handling process.
Application Objective The customer’s primary application objective required the ability to achieve optimum railcar loading efficiency by eliminating over and under loaded railcars during the blend and load process. In simple terms the weighing system needed to be fast and accurate with seamless integration into the customer’s traditional scrap handling and loading process. Control and data collection of the weighing system would also be required at two different locations in the yard via wireless network. Additional objectives required an economical approach for integrating the weighing system into the existing crane handling equipment. The weighing system would also need to be modular in design, with field replaceable components for prompt servicing and minimum downtime during 24/7 operations.
Solution The customer’s handling equipment consisted of a grapple attachment on an outdoor gantry crane. MSI designed and manufactured a custom size load pin to replace the existing interface pin between the crane block and grapple attachment. A load pin was selected for the load-sensing element due to its ideal location in line with application loading dynamics and safe distance from the high abuse area of the pick. The MSI-9000 CellScaleTM was the specified instrumentation to process the load pin output as it could also be integrated safely into the customer’s crane block and out of harms way. Since no local power was available from the crane, a 12-volt battery power supply was packaged in an industrial enclosure and secured in the crane block to power the MSI-9000 and load pin. The MSI-9000 was configured to network with two remote locations in the customer’s
scrap yard. The first location was at the crane cab where an operator could access, via an MSI-9850 RF indicator, total control over the weighing system with the ability to input associated data for each pick, including: operator, railcar and material ID and accumulated weights. Additionally, the same data was required at a second location where an interface with the customer’s PC was established for collection and downloading to their database. An MSI-9020 was networked with the weighing system at the second location where it received and processed data for interface directly with customer’s PC. The MSI-9020 and MSI-9850 provide connectivity via RS232, 4-20 mA and/or Ethernet. Contact MSI today for more information on CellScale network solutions and/or to arrange an application review and proposal.

Application Objective
Solution
Features and Benefits
A steel producer wanted to integrate a weighing system on their portable molten metal rail cars used for transporting molten metal to and from multiple locations within their plant. The weighing system needed to be self-powered, with remote indication and control that allowed operators to remain at safe distances from the molten metal.
Four compression load cells were placed under the crucible platform on each railcar. Their outputs were summed together using the MSI-9002 summing box after being wired to an MSI-9000 CellScale that was powered by a 12-volt rechargeable battery. The weighment information was transmitted from the CellScaleTM to an MSI-9850 RF digital indicator mounted in the control room and to MSI-9750A handheld RF digital indicators used by the operators.
The robust industrial packaging of the CellScale family of products is ideally suited to provide outstanding performance in demanding metal industry applications. The 12-volt SLA battery powered CellScale provided approximately 15 hours of continuous use between charges. The CellScale wireless network provided real-time weighment information to both the control room and operators. An added bonus was the internetwork radio messaging (standard feature on both the MSI-9850 and MSI-9750A) that enabled special instructions to be transmitted and received from the control room and operators.

Application Objective
Solution
A steel service center wanted to integrate a weighing system on their steel coil grabber to minimize headroom loss while capturing coil weights in process. Initially, the customer wanted to display the weights on a scoreboard within the plant. Their future plans were to integrate the coil weighment information directly with their host computer system.
Double-ended shear beam load cells were mounted on the coil grabber to sense the load through its interface pin. The load cell outputs were wired to an MSI-9000 CellScale that was powered by a 12V rechargeable battery. The weighment information was transmitted from the CellScale to an MSI-9020 CellModem that was connected to a wall-mounted scoreboard.
Features and Benefits The compact packaging and versatile mounting of the standard CellScale provided an easy integration with the double-ended
shear beam load cells on the coil grabber. The individual load cell outputs were summed by the CellScale for the system to transmit and display the total coil weight during each lift. Using a 12-volt SLA battery to power the CellScale and load cells eliminated the need for separate power cables and provided approximately 25 hours of continuous use between charges. The expandability objective can be easily accommodated by adding an additional MSI-9020 CellModem to the network for interfacing with their host computer system.

Features and Benefits
A processing plant wanted to integrate a multi-tank weighing system to monitor fluid levels in real-time. Access to power was near the tanks. However, their location was more than 1000 feet from the plant on the other side of the parking lot.
Installation of a simple, wireless CellScale network proved to be the most cost-effective solution. Four compression load cells were placed under each tank, their outputs were summed together using the MSI-9002 summing boxes, and wired to an MSI-9000 CellScale with the dual A/D option. This allowed one CellScale to be used with all three tanks. The CellScale was set up to communicate with the MSI-9850 RF digital indicator at the plant. Long range antennas were used on the transmitting/ receiving components to ensure reliable communication. TM
The CellScale wireless network installation saved considerable time and expense, allowing the parking lot to remain in tact by not having to bury cables to the MSI-9850 at the plant. The information display on the MSI-9850 enabled all three tanks to be monitored simultaneously; with a touch of a button operators could choose which tank to monitor on its large primary weight display. Setpoints were programmed for each tank to alert operators of low tank levels before they were empty.

Application Objective The maintenance manager at a major shipping port wanted to retrofit the load monitoring systems on their existing container cranes. The OEM equipment was not functioning properly and there was no service/support available. Simplicity and reliability were the key desired attributes along with local service and support.
Solution A variety of strain gauge sensor designs and multiple sensor locations can be utilized to monitor the loads on container cranes. Typical sensor designs include load pins to measure the load displaced on sheaves or wire rope dead-ends, compression load cells under sheave assemblies, and clamp-on wire rope load sensors. MSI designs and/or provides application specific sensors that accurately measure the load.
In this case, load sensors were installed on the boom tip of the container crane to sense the load through the sheave. The load cell outputs were hardwired to a non-RF MSI9000 CellScaleTM that was mounted in the machine house. Optional 4-20mA outputs on the CellScale were utilized to interface with the container crane’s PLC control system, and the standard MSI-9000 CellScale set points were programmed to trip safety interlocks for eccentric/unbalanced loads, overload and slack line conditions.
Features and Benefits The CellScale easily integrated with the existing control system in the machine house. Using the set point relay outputs on the CellScale to trip the safety interlocks provided a quicker reaction time that minimized
potential damage and improved crane safety. This simple installation proved very reliable for the port. MSI’s Authorized Distribution Network provided local service and support. An alternate solution is to use the wireless RF communication from the CellScale (mounted on the boom tip adjacent to the load cells) to a receiving modem in the machine house. Optional 4-20mA and set point outputs from the RF modem can be wired to the crane control system in the same manner as the non-RF solution. The key benefit of wireless communication is the freeing of conductors in the festoon.

Application Objective A boat manufacturer was seeking a solution to view and record accurate weights throughout multiple stages of the manufacturing process. The most vital application objective was to provide a means to determine the center of gravity for each manufactured vessel.
Solution During the manufacturing process the boat is lifted on a gantry crane utilizing four pick points and two hull support slings. In an effort to integrate the weighing solution within the confines of the gantry crane, the four pick points were selected for locating load sensors. To minimize modification to the existing crane and lifting rigging, MSI provided four custom dimensioned load links for in-line installation with current rigging at each pick point.
System Components To effectively process all four load link outputs simultaneously, the MSI-9000 CellScale was the choice instrumentation. The MSI-9000 provided the required capability to process each load link input independently and collectively towards calculating the center of gravity. In addition, the processed data required real-time transfer to a remote PC for viewing and recording. Utilizing the MSI-9000, with internal 2.4 GHz RF modem, allowed the collected data to be transmitted wirelessly in real time to a remote PC. Each stage of the manufacturing and weighing process is viewed, controlled and recorded at the PC station.

The second objective was to independently monitor each load sensor and perform comparative analysis while alerting the crane operator when an unbalanced load situation occurs. System relays would trigger when a load sensor and/or sum of their outputs exceeded 125% of capacity. If an under load condition occured, it would trigger a relay and register the load, at or below zero, referred to as a “slack-line” condition.
MSI designed and manufactured custom load sensors that did not require modification to existing interfacing hardware. Based upon design requirements, a clevis lug mechanical design was selected for the load sensing elements.
Additional objectives included a user-friendly interface for remote load indication and control. Its location was approximately 380 feet (116 meters) from load sensors, and required a relay reaction time of less than one second.
Although RF technology was not used, the MSI-9000 CellScaleTM without an RF modem was the specified instrumentation to process sensor inputs. With an optional second dual channel A/D, the CellScale processed and retained calibration data for each of the four load sensors. To optimize the customer’s “balancing” routine and relay response time, a panel-mounted touch screen computer with MSI CVM (CellScale Virtual Monitor) software was specified. Both the computer and system’s external relay module were interfaced via Ethernet. The computer processes each of the routine’s calculations to determine relay
