PT-201D diffusion Silicon Pressure Sensor description:

PT-201D diffusion silicon pressure sensor adopts the silicon resistance differential pressure oil-filled core of an internationally renowned company. Through a highly reliable amplification circuit and precise digital temperature compensation and non-linear correction technology, the pressure of the measured medium is converted into 4~20mA, 0~ 10VDC analog signal and IIC, RS485 and other standard digital signals. Coupled with the versatile Herschmann plug, it ensures excellent product quality and optimal performance. Users can conveniently, quickly and accurately measure the pressure of various fluids. The ultra-high cost performance can be widely used in differential pressure, liquid level and flow measurement and control in process control, aviation, aerospace, automobiles, medical equipment, HAVCD and other fields.
