EPRO PR9268/202-000 vibrating sensor

The EPRO PR9268/202-000 vibration sensor is a high-performance eddy current sensor designed for vibration measurement in various industrial and laboratory applications. The following are the details and features of the sensor:

Basic information
Brand: EPRO
Model: PR9268/202-000
Type: Eddy current sensor (vibration sensor)
Main feature
Widely used: It is widely used in various turbine-machinery, such as fans, compressors, gear boxes, pumps, etc., as well as many fields of industrial measurement.
Non-contact measurement: has the advantage of non-contact measurement, can measure the gap between the rotating part and the fixed part, shaft vibration and eccentricity and other physical quantities.
High temperature environment: Especially suitable for high temperature environment, such as sensors PR 9268/60 and PR 9268/70 are especially suitable for high temperature environment.
High reliability: Small size, high reliability, robust construction allows installation in hazardous environments.
Waterproof and dust-proof: Waterproof protection level up to IP 55 or IP 65, ensuring stable operation in harsh environments.
Technical parameter
Frequency range: Two frequency ranges are provided, namely 10 HZ-1000 Hz and 4 HZ-1000 Hz.
Measuring range: The maximum amplitude can be measured up to 2mm, and some models can even reach 3mm (peak-to-peak).
Output signal: provides a voltage signal proportional to the vibration speed.
Explosion-proof rating: When connected to the safety grid, the explosion-proof rating reaches EEx ib II B/II C, in accordance with the relevant European standard EN 50014/50020.
Operating temperature: The operating temperature can reach 200°C, which is suitable for measurement in high temperature environment.
Working principle
The EPRO PR9268/202-000 vibration sensor consists of a seismic block and a measuring coil supported by a spring. The measuring element moves in the magnetic field of the circular magnet. When the sensor housing vibrates, a voltage signal is generated that is proportional to the vibration speed.

Application field
The sensor is widely used to measure frequencies in the 10… 1000Hz and 4… 1000Hz mechanical vibration, such as various turbomachines, fans, compressors, gear boxes, water pumps, coal ladders, etc.
