PCM3701 Urea Dosing Pump Pressure Transmitter
The Urea Dosing Pump Pressure Transmitter is a type of 16mm medium isolated silicon piezoresistance pressure sensor designed for the automobile, and realizes the transmission to the sensing element through SS316L diaphragm; the Urea Dosing Pump Pressure Transmitter is designed specially for high performance and low pressure application. The custom-made ASIC is used for temperature compensation, offset correction, and provides the amplified output of 0.5 to 4.5V. This model may also come with a cable if desired.

Notes:
- The maximum pressure that can be applied without changing the sensor performance or accuracy;
- The maximum pressure that can be applied to the transducer without rupture of either the sensing element or the transducer;
- The measured medium dead volume that exceeds 350mm3 may damage the sensor in the frozen state.
