EPRO PR6426/010-110 Sensor

The EPRO PR6426/010-110 sensor is a powerful eddy current sensor, mainly used for non-contact measurement of static and dynamic displacement. The following is a detailed introduction to the sensor:

Main features:

Non-contact measurement: The sensor can accurately measure without direct contact with the object being measured.

Multiple applications: Suitable for axial and radial shaft displacement, shaft eccentricity, shaft vibration, bearing wear, oil film thickness and crack detection and other application scenarios.

Compliance with multiple standards: Complies with multiple general standards such as API 670, DIN 45670, ISO 10817-1.

High explosion-proof level: It can be used in explosion-proof environments, and the explosion-proof level can reach Eex ib IIC T6/T4.

Wide application: Widely used in steam turbine monitoring and protection systems MMS 3000 and MMS 6000, as well as various industrial fields and laboratories.

Technical specifications:

Sensor signal input: There are two independent eddy current sensor signal inputs, SENS 1H(z8)/SENS 1L(z10) and SENS 2H(d8)/SENS 2L(d10).

Input voltage range: Typically -1…-22 V dc, but may vary depending on the specific application.

Power supply: The module provides two -26.75 V dc power supplies for the sensor, SENS 1+(z6)/SENS 1-(b6) and SENS 2+(d6)/SENS 2-(b8).

Signal output: The module has two TTL pulse outputs with a voltage range of 0…+5V. The width and frequency of the pulse are related to the sensor signal.

Key phase signal output: The module also has a key phase signal input (must be greater than 13V), which is required for the eccentricity value calculation.

Calibration and installation:

Factory calibration: The sensor and the preamplifier have been linearly calibrated using the calibration material 42CrMo4 before leaving the factory, so calibration is usually not required during installation.

Installation adjustment: The user only needs to adjust the air gap between the sensor and the measuring surface until the required signal is obtained from the output of the preamplifier.

Application areas:

The sensor can be widely used in the monitoring and protection of various turbomachinery, fans, compressors, gearboxes, water pumps, coal mills and other equipment.

It is especially suitable for monitoring high temperature environments, such as sensors PR 9268/60 and PR 9268/70 are particularly suitable for high temperature environments.

In summary, the EPRO PR6426/010-110 sensor is a powerful and widely used eddy current sensor with high accuracy, high reliability and multiple application scenarios.
