EPRO PR6426/010-110 Differential expansion sensor

The EPRO PR6426/010-110 differential expansion measuring probe (also known as differential expansion sensor) is a high-performance industrial measurement device primarily used to measure mechanical vibration and displacement. Here are the details about the sensor:

Product Overview:
The EPRO PR6426/010-110 is a differential expansion measuring probe that, together with the preprocessor, forms an oscillator. Its amplitude decays with the proximity of the sensor probe to the metal object, and the amplitude of the attenuation is proportional to the distance between the sensor and the object.
The sensor series is used to measure frequencies in the 10… 1000Hz and 4… 1000Hz mechanical vibration, the maximum amplitude up to 2mm, some models even up to 3mm (peak-peak).
The robust structural design enables it to be installed in dangerous environments, and is widely used in various turbo-machines, fans, compressors, gear boxes, water pumps, coal ladders, etc.
Product features:
Eddy current sensor principle, non-contact measurement, suitable for static and dynamic displacement measurement.
The sensor and preprocessor have been linearly calibrated in complete sets using calibration material 42CrMo4 before delivery, so no calibration is required during installation.
The sensor provides a voltage signal that is proportional to the vibration speed and is widely used in many fields of industrial measurement.
Suitable for explosion-proof environment, explosion-proof level can reach Eex ib IIC T6/T4.
Technical specifications:
Measuring frequency range: 10… 1000Hz and 4… 1000Hz.
Maximum amplitude: up to 2mm or 3mm (peak-to-peak).
Signal output: Voltage signal proportional to vibration speed.
Power supply voltage: Specific parameters may vary by model, but usually include DC power supply.
Application field:
It is mainly used in industrial scenarios requiring high-precision vibration and displacement measurement, such as turbine monitoring and protection systems, generator sets, wind power generation equipment, petrochemical equipment, etc.
Installation and calibration:
The user only needs to adjust the air gap between the sensor and the measuring surface until the desired signal is obtained from the output of the preprocessor.
Since the linear calibration has been carried out before leaving the factory, no additional calibration is required during installation.
Note:
In the installation and use process, it should be ensured that the gap between the sensor and the measured object is appropriate to avoid too close or too far resulting in inaccurate measurement.
The sensor should be installed in a dry, dust-free, non-corrosive gas environment to ensure its normal operation and service life.
In summary, the EPRO PR6426/010-110 differential expansion measuring probe is a powerful and stable industrial measuring equipment, widely used in a variety of industrial scenarios requiring high-precision vibration and displacement measurement.
