EPRO PR6423/03R-010+CON021 8mm eddy current sensor
PR6423/03R-010+CON021 is a complete EPRO (Emerson) 8mm eddy current measurement system, including PR6423 probe (with armored cable) and CON021 preamplifier. Based on the principle of non-contact measurement of eddy current, the preamplifier generates a high-frequency alternating magnetic field, and the probe senses the eddy current changes on the metal surface of the rotor, converting the gap changes between the probe and the shaft into a continuous voltage signal. PR6423/03R-010+CON021 is used to measure radial shaft vibration, shaft displacement, eccentricity, speed, and key phase signals of rotating machinery. The output signal is sent to TSI monitoring and protection systems such as MMS3000/MMS6000. The system can monitor the dynamic status of the rotor in real time, trigger alarms and interlocks when vibration or displacement exceeds the standard, and avoid shaft rubbing and bearing damage. It is the core sensing component of TSI status monitoring and protection for steam turbines and compressors.
Main function:
- Non contact measurement, the probe does not come into contact with the rotating rotor, there is no mechanical wear, and it is suitable for long-term continuous monitoring of high-speed rotating shafts.
- Complete factory calibration, matching probe cables and preamplifiers one by one to ensure measurement linearity and accuracy, and cannot be interchanged arbitrarily.
- The probe is equipped with a stainless steel armored cable, which is resistant to compression, wear, and high temperature, suitable for the high-temperature vibration environment of the unit body.
- Wide frequency response, capable of simultaneously collecting static clearance and dynamic vibration waveforms, taking into account shaft displacement and shaft vibration measurement.
- The CON021 preamplifier has built-in fault diagnosis, which can detect probe disconnection and short circuit faults to prevent false alarms on site.
- Fast response speed, with a rise time of less than 15 μ s, capable of capturing high-frequency impact vibration signals of the rotor.
- Meet the API670 rotating machinery protection standard and support up to SIL3 safety level in overspeed application scenarios.
- Output composite voltage signal, which can be directly connected to MMS series TSI monitoring module and adapted to the entire EPRO monitoring system.
- Vibration resistant and wide temperature design, capable of withstanding harsh working conditions such as high temperature, humidity, and strong vibration in power plants and petrochemical sites.
- Easy installation and debugging, the probe installation gap can be intuitively set through the gap voltage, and on-site verification is simple.
