The piezoresistive pressure sensor uses TM's piezoresistive pressure sensor core as the sensor sensor. The pressure sensor converts the pressure of the liquid or gas into a standard electrical output signal of 4-20 mA, 0.5~4.5 VDC. The P25 piezoresistive pressure sensor is built with a piezoresistive pressure sensor built into a stainless steel housing with a pressure port. This product is an electronic device that converts physical variables (pressure) into electrical signals (current or voltage) that can be read or acquired by various control, measurement, and conditioning devices. The piezoresistive pressure sensor is applied to the zero point and range of laser trimming hybrid compensation sensor, and is widely used in pressure calibration devices, automobiles, plastic rubber injection machines, punching machines and metal processing machinery, industrial measurement, HVAC and other fields.
