Urea Pump Product Pressure Sensor PCM107

Overview

The product is a small mounted piezoresistive pressure

 sensor, 316L stainless steel package, plastic housing

and connection head, O-ring seal, which suit for various

kinds of medium pressure applied to the steel diaphragm

transmitted to the pressure chip through silicone oil. It

suits for high precision, small range applications,

temperature compensation, deviation correction and

amplification functions (0.5V to 4.5V output). The sensor

is CE certified and designed and produced according to

TS16949 standard.
