EPRO PR6423/013-130 CON021 displacement sensor

The EPRO PR6423/013-130 CON021 displacement sensor is a sensor system specially designed for measuring the displacement of various industrial equipment. The following are the details and features of the sensor system:

Product overview
Make and Model: EPRO PR6423/013-130
Matching preprocessor: CON021
Type: Displacement sensor
Application: It is mainly used to measure the opening stroke of the valve position of the turbine unit. With the oil motor monitoring instrument, it can realize the functions of remote indication, alarm and constant current output of the valve position stroke.
Technical parameter
Range: According to the specific application, the range can be customized, but usually the displacement sensor PR6423 series has a range of 0 ~ 300mm.
Accuracy: ±1% (full scale) to ensure the accuracy of measurement results.
Working environment:
Ambient temperature: -10℃~+180℃
Relative humidity: ≤90%
Sensing element: The medium frequency differential transformer displacement sensor is a highly reliable LVDT displacement sensor.
Shell: stainless steel material, with simple structure, high precision, no protection and other advantages.
Working principle
The displacement sensor adopts the principle of non-contact measurement and forms an electric oscillator in combination with the matching preprocessor CON021. When a metal target, such as a valve or shaft, approaches the sensor probe, the oscillator’s amplitude is suppressed by an amount proportional to the distance between the sensor and the measured object. By measuring this change in amplitude, the amount of displacement can be precisely calculated.

peculiarity
High accuracy: Using highly reliable LVDT displacement sensors to ensure the accuracy of measurement results.
Non-contact measurement: no direct contact with the measured object is required to avoid interference and wear on the measured object.
Widely applicable: Suitable for displacement measurement of various turbine machinery, fans, compressors, gear boxes, water pumps, coal ladders and other equipment.
High explosion-proof rating: After the installation of the safety grid, the sensor and the preloader can also work in the environment where explosion-proof is required, and the explosion-proof rating can reach Eex ib IIC T6/T4.
Application field
It is widely used in steam turbine monitoring and protection systems (such as MMS3000 and MMS6000 monitoring systems), as well as various industrial equipment in chemical, petroleum, electric power, metallurgy and other industries.
