Technical Specifications

Installation Guidelines

• Ensure the Proximitor sensor is mounted in a protected, dry location, ideally within a weatherproof housing if installed outdoors.
• Use shielded coaxial cabling for all connections to minimize electromagnetic interference (EMI).
• Maintain proper grounding practices to ensure signal integrity and protect against ground loops.
• Verify that the system length matches the configuration of the monitoring system; do not modify cable lengths without recalibration.
• Power down the monitoring system before connecting or disconnecting the sensor to prevent electrical damage to the input circuitry.

FAQ

What is the primary function of the 330878-91-00?

This unit is a Proximitor sensor used to measure the distance (gap) between the probe tip and the observed target, typically a rotating shaft, to monitor vibration, position, or speed in industrial machinery.

Is this sensor compatible with all 3300 series systems?

The 3300 XL series is designed for specific compatibility. Please verify your monitoring system's manual to ensure the 50 mm sensor configuration is supported by your existing monitor card or interface module.
