Product Description

High Temperature and High Pressure Quartz Crystal Pressure Sensor

SG-QUP series high temperature and high pressure quartz pressure sensors have high reliability and high precision.

For decades, the international petroleum industry has been taking this kind of quartz crystal pressure gauge as the industry pressure measurement standard.The pressure sensitive element is a quartz resonator, and the output frequency varies with the applied pressure.

The sensor maintains the excellent characteristics of high repeatability and high stability inherent in single crystal quartz.

High Temperature and High Pressure Quartz Crystal Pressure Sensor Features:

✮ Small dimension

✮ Low loss

✮ High repeatability and stability

✮ It can be easily applied to the ready-made storage logging tool or wireline logging tool

✮ The signal output can meet the requirements of various measuring circuits.
