The PR6424/010-140 CON021 is a combination of eddy current sensors and preprocessors from Emerson's EPRO brand. Here's how:

Product Overview: The PR6424/010-140 is an 8mm eddy current sensor, usually used with the CON021 preprocessor. The sensor is a non-contact sensor designed for critical turbine-mechanical applications such as steam, gas and water turbines, compressors, pumps and fans.

Working principle: The sensor and the preprocessor form an oscillator, and when the sensor probe is near the metal object to be measured, the amplitude of the oscillator will be attenuated, and the attenuation amplitude is proportional to the distance between the sensor and the object to be measured. Using this principle, the distance change can be converted into electrical signal change, so as to realize the measurement of displacement and other physical quantities

PR6424/010-140 CON021 Features

High-precision measurement: It can accurately measure the dynamic displacement, position, eccentricity and speed of the radial and axial axes, and provide accurate data for the monitoring of the operating status of the equipment.

Channel monitoring function: The preprocessor can check the DC voltage value of the input signal. When the input signal exceeds the set normal upper limit of the channel or is lower than the set lower limit, it will give the channel error indication, such as the sensor short circuit or open circuit. When using a Hall effect sensor, the signal voltage may exceed the supply voltage at high frequencies, and the normal upper limit of the channel should be set at 27.4V.

Gap error indication: If the input signal is lower than the gap limit, the module will give a gap error indication in the software Status, and the channel normal indicator of the corresponding channel will blink at a frequency of 0.2 seconds.

PR6424/010-140 CON021 Application field

Power industry: Used for turbine, generator and other equipment shaft displacement, shaft vibration and other parameters monitoring, to ensure the safe and stable operation of equipment.

Petrochemical industry: In compressors, pumps and other rotating machinery and equipment, monitoring the status of the shaft, timely detection of equipment failure hazards.

Other industrial fields: such as metallurgy, paper, pharmaceutical and other industries of large rotating equipment, also often use the sensor for condition monitoring.

These are EPRO brand PR6424 series of eddy current sensor models, their basic working principle and application scenarios are the same, but in some specific parameters may be different, the following is your specific introduction:

Working principle: All belong to the eddy current sensor, and the preprocessor together form an oscillator. When the sensor probe is close to the metal object to be measured, the amplitude of the oscillator will be attenuated with the reduction of the distance between the two, and the attenuation amplitude is proportional to the distance, so that the distance change is converted into the electrical signal change, to achieve the measurement of physical quantities such as displacement.

Application scenario

Rotating equipment monitoring: can be used to measure turbine, compressor, pump and other rotating machinery shaft vibration, shaft displacement, shaft eccentricity and other parameters, to ensure the stable operation of equipment.

In the field of industrial automation, the position and displacement of moving parts are accurately measured and controlled on the production line to ensure the accuracy and consistency of the production process.

Other fields: Monitoring and measuring parameters such as displacement and vibration of key components in related equipment in aerospace, metallurgy, paper and other industries.

Difference analysis: The suffix number in the model may represent different configurations or parameters, such as the length of the sensor, cable length, installation method, etc. Taking PR6424/010-XXX, PR6424/011-XXX, etc., as an example, the middle 010, 011, etc., may be related to some specific specifications of the sensor, such as probe size, sensitivity fine-tuning, etc.; The final XXX is generally related to the total length of the sensor or the length of the cable, such as 100, 110, 120 May correspond to different length specifications, the larger the number, the longer the length may be
