PT-201 Economical Pressure Transmitter

Principle: The pressure sensor works based on the Wheatstone bridge principle. Its high temperature resistance can be applied to special industries, making it an ideal product for measuring and controlling high-temperature liquid pressure in mechanical equipment such as rubber, plastic, and chemical fiber. Due to the piezoresistive effect of the pressure sensor, the bridge generates a highly linear voltage signal that is proportional to the pressure and excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3mV/V according to the different pressure ranges, and is compatible with strain gauge sensors. Through laser calibration, the sensor has high temperature stability and time stability. The sensor has its own temperature compensation of 0~70℃ and can be in direct contact with most media.
