Description

The Bently Nevada 18745-03 is a precision Proximitor sensor designed for use with 5 mm and 8 mm proximity probe systems. This sensor acts as the interface between the probe and the monitoring system, converting the probe's signal into a linear voltage output proportional to the distance between the probe tip and the observed target. It is a critical component in vibration monitoring and displacement measurement applications for rotating machinery.

Features

• Compatible with 5 mm and 8 mm proximity probe configurations.
• Standard scale factor of 200 mV/mil for accurate displacement measurement.
• Wide frequency response range from 0 to 10 kHz (±3 dB).
• Rugged design suitable for industrial monitoring environments.

Technical Specifications

Installation Guidelines

• Ensure the Proximitor sensor is mounted in a protected, dry environment, typically within a junction box or instrument housing.
• Use high-quality, shielded coaxial cabling to connect the probe to the sensor to minimize electromagnetic interference (EMI).
• Maintain proper grounding practices for the sensor housing to ensure signal integrity and system safety.
• Verify that the power supply voltage is within the specified -24 V DC to -26 V DC range before energizing the unit.
• Handle the sensor with care; avoid sharp bends in the coaxial cable to prevent damage to the signal path.

FAQ

What is the primary function of the 18745-03?

The 18745-03 Proximitor sensor conditions the signal from a proximity probe, providing a linear voltage output that represents the gap between the probe tip and the target, which is essential for monitoring shaft vibration and position.

Is this sensor compatible with both 5 mm and 8 mm probes?

Yes, the 18745-03 is designed to support both 5 mm and 8 mm proximity probe systems, provided the system is calibrated correctly for the specific probe type used.
