Epro PR6424/016-100 16mm Eddy Current Sensor

Product Introduction

The Epro PR6424/016-100 16 mm Eddy Current Sensor is a high-precision, non-contact displacement probe designed for continuous vibration and shaft-position monitoring in industrial machinery. Leveraging advanced eddy-current technology, it provides accurate measurements of both static and dynamic shaft displacement without physical contact, reducing maintenance requirements and increasing operational reliability. Its 16 mm stainless-steel sensor head, combined with robust IP67 housing, ensures performance in extreme industrial conditions, including high temperatures, high vibration, and chemically aggressive environments.

• Wide Temperature Range – Operates reliably between −35 °C and +180 °C.

• Fast Dynamic Response – DC to 10 kHz frequency response captures both slow and high-frequency vibrations.

• Non-Contact Operation – Reduces mechanical wear, lowering maintenance requirements and extending sensor life.

• Flexible Integration – Compatible with CON021 driver modules and most industrial monitoring systems.

FAQ

1. Which driver module is recommended for the PR6424/016-100?
   The Epro CON021 driver is recommended for precise excitation, calibration, and temperature compensation of the sensor.

2. How does the sensor maintain stability under extreme temperatures?
   The sensor uses temperature-stable coil materials and relies on the CON021 driver’s compensation circuitry to maintain measurement accuracy across −35 °C to +180 °C.

3. What is the linear measuring range of the sensor?
   The sensor has a linear range of ±2 mm around the mid-gap, suitable for standard industrial shaft monitoring.

4. Can the PR6424/016-100 function in high-vibration environments?
   Yes, it withstands continuous vibrations up to 20 g over the 10–2 000 Hz frequency range without signal degradation.

5. Is the sensor compatible with non-Epro monitoring systems?
   Yes, it can integrate with third-party systems provided proper impedance matching and calibration are performed.

6. What frequency range does the sensor support?
   DC to 10 kHz, allowing it to capture both slow shaft movements and high-frequency vibration events accurately.

7. Is field calibration required?
   Yes, field calibration is recommended using a precision micrometer gap reference to adjust the driver’s zero and gain.

8. Can the sensor be used in hazardous areas?
   An ATEX-certified version is available for safe operation in Zone 1 or Zone 2 hazardous environments when used with approved barriers.

9. What type of output signal does it provide?
   The sensor delivers a voltage signal proportional to shaft displacement at 8 mV/µm, compatible with most vibration monitoring systems.

10. How does the sensor prevent wear during operation?
    The non-contact eddy-current design ensures no physical contact with the shaft, eliminating mechanical wear and extending operational life.
