Flush diaphragm pressure sensor HPC23

Products Overview

Holykell HPC23 flush diaphragm pressure sensor is a full-welded pressure sensor, it has pressure port G1/2 male or M20X1.5 male, sealing by Viton O-ring at the end of thread. The isolated diaphragm is welded in front of thread port, the whole measure range is -100kPa10kPa…7MPa. CYX23 series OEM piezoresistive pressure sensor adopts imported die with high accuracy and high stable. It can be used for surface of the viscous medium, absolute pressure and pressure measurement occasions without obvious corrosion to 316L stainless steel.

Remarks














Order Note:
     1.We suggest you to use Floating construction when you install the sensor to prevent affecting sensor stability;
     2.Please pay attention to protect sensor isolated diaphragm and ceramic compensated board, to avoid damaging sensor and affecting the performance;
     3.When the temperature exceeds viton working temperature, or the user needs sensor at rugged environment, please contact our company freely.
