EPRO PR6423/002-030+CON021

The EPRO PR6423/002-030+CON021 is an integral part of a steam turbine monitoring system consisting of the speed probe PR6423/002-030 produced by EPRO (or Philips) and the preprocessor CON021. Here is a detailed explanation of this combination:

Speed probe PR6423/002-030
Make and Model: EPRO (or Philips) brand PR6423/002-030 tachometer probe.
Type: The probe is a shaft vibration sensor that measures the vibration displacement or amplitude of the shaft in a non-contact manner.
Working principle: The vibration of the object is measured by the change in the distance between the sensor end and the object being measured.
Features: It has the advantages of wide frequency range (0 ~ 10 kHZ), large linear working range, high sensitivity and non-contact measurement.
Preprocessor CON021
Type: CON021 is a signal converter used with the PR6423/002-030 probe to form a complete eddy current measurement chain.
Working principle: Based on the eddy current effect, it consists of a flat coil fixed on the frame, and the distance between the measured body is judged by the strength of the reverse electromagnetic field.
Features:
Compatibility: Designed for PR6422, PR6423, PR6424, PR6425, PR6426 and other models of sensors, with good compatibility.
Stability: Powerful, stable performance, widely used in industrial automation, process control and key turbomachinery applications.
Accuracy: It has different accuracy when connecting different sensors, for example, the linear error is less than 1.0% when connecting PR6423.
Power supply and output: The power supply and output signal are connected by screw terminals, and can be connected to the sensor with the bare end wire by screw terminals or by LEMO plugs.
Protection level: IP20, connected to sensor via LEMO plug.
System combination (PR6423/002-030+CON021)
Application scenario: Widely used in steam, natural gas and hydraulic turbines, compressors, pumps, fans and other key turbomachinery applications, to help users real-time monitoring equipment operating status, timely detection of potential problems and treatment.
System monitoring: The internal module monitoring circuit can continuously monitor the sensor signal, the status of the connection cable between the sensor and the module, and whether the system power supply voltage is within the preset range.
Limit detection: In dual-channel mode, the characteristic values of channel 1 and channel 2 are monitored by yellow and red alarm lights respectively; In single-channel mode, limits can be set, such as yellow for alarm and red for danger.
Sum up
The EPRO PR6423/002-030+CON021 turbine monitoring system is a powerful and stable system that enables accurate measurement of radial and axial axial displacement, position, eccentricity and speed, and is widely used in industrial automation and critical turbinomachine applications.
