Product Details

PT-201 Economic Pressure Transmitter

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

Features: The transmitter uses a high temperature melt pressure sensor. Simple structure, small size, easy installation, suitable for gas and liquid media compatible with the material of the contact part. Can measure gauge pressure, absolute pressure and negative pressure.
