EPRO PR6423/016-030+CON021

Product Overview

PR6423/016-030 + CON021 is not a single product, but a highly matched and collaborative complete eddy current displacement/vibration measurement solution, specifically designed by German Epro for the condition monitoring and protection of critical rotating machinery.

PR6423/016-030 is a non-contact eddy current sensor with a probe diameter of 8mm. Be responsible for accurately sensing the minute displacement changes on the surface of the shaft without touching the measured shaft.

CON021 is an eddy current signal converter. Installed in the control room far from the harsh on-site environment, it is responsible for providing high-frequency excitation signals for the sensors and linearly converting the weak impedance changes sensed by the sensors into standard, highly anti-interference -2V to -18V or -4V to -20V DC voltage signals for use in the monitoring system.

This combination is the gold standard for monitoring the shaft vibration, axial displacement, eccentricity and rotational speed of high-speed rotating equipment such as steam turbines, gas turbines, compressors, pumps and fans in modern industry. Its core value lies in non-contact, high precision and high reliability, which can provide key data related to the safe operation of equipment under extreme temperature, pressure and electromagnetic interference environments.

Product Functional Features

The core advantage of this system lies in its precise mechatronic design and adaptability to harsh industrial environments.

Non-contact and wear-free measurement

There is a fixed air gap maintained between the sensor and the rotating shaft, with no physical contact. This eliminates mechanical wear, ensuring an unlimited service life and extremely high measurement stability, making it particularly suitable for high-speed and high-temperature shaft system monitoring.

Extremely high dynamic response performance

The frequency bandwidth of 20kHz and the rise time of less than 15µs enable PR6423/016-030+CON021 not only to precisely capture the low-frequency shaft displacement but also to accurately reflect the high-frequency shaft vibration, providing a high-quality data foundation for early fault diagnosis.

Outstanding environmental adaptability and reliability

Sensor. The IP66 protection, operating temperature range of -35°C to +180°C, stainless steel housing and PTFE high-temperature resistant cable enable the PR6423/016-030+CON021 to be directly installed in harsh sites near high-temperature bearing boxes or steam environments.

Converter. Although installed in the control room, the wide temperature range and multiple international explosion-proof certifications ensure the compliance and safety of the entire signal link in various industrial scenarios.

Precise linearization and temperature compensation

The entire system is calibrated as a whole. The internal circuit of CON021 has been optimized for a specific model of PR6423, effectively compensating for sensitivity drift caused by temperature changes and ensuring high linearity and stable output throughout the entire operating temperature range.
