EPRO PR6423/003-030+CON021 temperature sensor

The EPRO PR6423/003-030+CON021 is not actually a temperature sensor, but more accurately, it is part of a thermal expansion sensor system related to temperature monitoring. Here is a detailed explanation of the system:

Basic information
Brand: EPRO
Model: PR6423/003-030 + CON021
Sensor types and functions
PR6423/003-030: This is a thermal expansion sensor mainly used to measure the amount of expansion displacement of steam turbine cylinders. It is used with XCW-R thermal expansion monitor, and can complete the functions of remote indication, alarm and constant current output of thermal expansion displacement.
CON021: This is usually a preprocessor or signal processor used in conjunction with the PR6423/003-030 sensor to provide signal conversion and enhancement.
Technical parameter
Range: Generally 0 ~ 50mm (but the range can be customized by the user)
Accuracy: ±1% full scale
Ambient temperature: -20℃ ~ +100℃
Relative humidity: ≤80%
Sensor probe length: 55mm (consult and replace longer model if necessary)
Application field
The sensor system is widely used in steam turbines and other industrial equipment requiring accurate measurement of thermal expansion displacement.
Working principle
The intermediate frequency differential transformer displacement sensor is used as the sensing element, which has the characteristics of high reliability, strong resistance, good linearity, simple structure and easy damage.
