THUW1103HP Universal Wireless Temperature Transmitter
Introduction
Extreme low power Long battery life Long distance range (5 Km LoS) Universal sensor input Real time transmission The Tekon Electronics In Head Wireless Universal Temperature Transmitter is specifically designed to meet the most rigorous requirements of operation in the industrial process environments. Due to its reduced dimension it may be installed in the DIN Form B sensor connection head in place of the traditional terminal block or current loop temperature transmitter. The THUW1103HP has an extreme low power operation mode that guaranties a long battery life. In its high power mode it can communicate over a long distance range (up to 5 Km Line of Sight). It accepts the most commonly used temperature sensors. The measured information (Sensor Temperature, Ambient Temperature, RF Signal Strength and Battery Status) is transmitted wireless to the receiver WGW1104HP and become available on the RS485 interface with Modbus protocol and in an analog current output. The operating parameters like the sensor probe type and transmission interval can be easily configured using the OTA - Over The Air setup and configuration function. The Battery level and RF link quality may be verified on site during the installation process.
