GH13P TIGG0931A.01
The GH13P is in combination with the M8 glow-plug adaptor AG04 a nearly flush mounted solution for diesel engines. It allows measurements without pipe oscillations and pressures of up to 250 bar. The GH13P comes with an M3 connector which allows the smallest installation tool clearance diameters. The adaptor dimensions are custom tailored to the requirements of the customer. The sensor is equipped with SID Sensor Identification for the use of SDM Sensor Data Management.
