Epro PR6426/010-030 Eddy current non-contact displacement and vibration sensor

FAQ

Q1: What is the PR6426/010-030 sensor mainly used for?
It is designed for non-contact measurement of shaft displacement, vibration, and position in heavy rotating equipment such as turbines, compressors, pumps, and fans.

Q2: What measurement principle does the PR6426/010-030 use?
The probe works using eddy current technology, detecting changes in the electromagnetic field caused by the distance between the sensor and a conductive metal surface.

Q3: What is the linear measuring range of the sensor?
The PR6426 series provides a typical linear measurement range of ±4.0 mm around the nominal air gap.

Q4: What materials are suitable for measurement?
The sensor is optimized for conductive ferromagnetic materials, commonly steel shafts such as 42CrMo4 or AISI 4140.

Q5: What temperature environments can the probe operate in?
The probe operates from −35 °C to 180 °C and can tolerate short excursions up to 200 °C.

Q6: What shaft diameter is recommended for reliable measurement?
For accurate measurement results, the shaft diameter should be at least 200 mm.

Q7: What environmental resistance does this sensor provide?
It withstands industrial shock and vibration of about 5 g and pressure up to 6,500 hPa, making it suitable for harsh industrial environments.

Q8: Does the PR6426/010-030 require a signal converter?
Yes, the sensor typically works together with compatible signal converters such as CON011 or CON021 to provide conditioned output signals for monitoring systems.
