Product details

Silicon Pressure Sensor

Description of Silicon Pressure Sensor

Based on silicon piezoresistive technology, UPX6-a, -b, and -c are manufactured by adopting high quality piezoresistive silicon chips.

UPX6-a silicon piezoresistive pressure sensor is the ultra-thin design based on UPX19 foundation.

UPX6-b silicon piezoresistive pressure sensor is manufactured by using UPX-19's manufacturing techniques. It is designed for application of high pressure situation. Its small diameter causes  the strength on the sensor body reduce greatly after installation.

UPX6-c silicon piezoresistive pressure sensor is manufactured by using UPX-19's manufacturing techniques. Except their outer diameters and lengths, other technical specifications of these sensors are completely same.

Features of Silicon Pressure Sensor

◇Computer tested, high precise compensation

◇Good performance, high reliability

◇Imported pressure silicon dies

◇Isolated-type structure, suitable for many kinds of media measurement
