150%F.S. Pressure Sensor Cell , Long Term Stability Pressure Detector Sensor Core
Pressure sensor core PS21 Flush diaphragm pressure sensor core
Feature
● Low cost, small size
● TO8 packing, enable for PCB installation
● Suitable for measurement of non-conductive & non-corrosive media
Applications
● Industrial process control
● Wastewater and environmental engineering
● Liquid pressure system and switch
Description
Based advanced ion implantation and micro-mechanical processing technology,PS21 TO8 housing piezoresistive pressure sensor is manufactured based on silicon chip which has Wheatstone Bridges and precise mechanical structure.
The measured pressure acts on silicon die through pressure port directly, and the pressure value is transformed to output voltage signal in linearity-relationship.
The pressure sensor is temperature compensated by means of laser trimmed technologies, TO8 housing makes it suitable for PCB mounting application, or installed in small space fields for pressure measurement of gas or liquid media.
PS21 pressure sensor has been widely used for air pressure control, physiology guarding, medicine equipment.
