Description

The Bently Nevada 330780-91-00 is a component of the 3300 XL 11 mm Proximity Transducer System. This system is designed for non-contacting vibration and position measurements in industrial machinery, providing high-reliability monitoring for critical rotating assets. The 330780 model is specifically configured for a 9.0-meter system length and is designed for DIN-rail mounting, ensuring compatibility with standard industrial control panels.

Features

  • Designed for 11 mm proximity probe applications.
  • System length of 9.0 meters (29.5 feet) for flexible installation.
  • DIN-rail mounting configuration for streamlined cabinet integration.
  • High-precision non-contacting measurement of shaft vibration and position.
  • Robust design suitable for harsh industrial environments.

Installation Guidelines

  • Ensure all power is disconnected before installing or removing the proximity sensor.
  • The probe and extension cable should be routed away from high-voltage power lines to minimize electromagnetic interference (EMI).
  • Verify that the system voltage is within the specified range (-17.5 Vdc to -26 Vdc) to maintain linear range accuracy.
  • Follow standard ESD (Electrostatic Discharge) handling procedures when working with the sensor components.
  • Ensure the probe tip is installed with the correct gap as specified in the machine monitoring system documentation.

FAQ

What is the primary function of the 330780-91-00?

This unit acts as a proximity sensor interface for the 3300 XL 11 mm system, converting the signal from a proximity probe into a voltage output proportional to the distance between the probe tip and the observed target, such as a rotating shaft.

Can this sensor be used with different system lengths?

No, the 330780-91-00 is factory-calibrated for a 9.0-meter system length. Using a different cable length will affect the calibration and accuracy of the transducer system.
