Product Introduction
BENTLY 330980-51-00 is a 3300 XL 8mm proximitors for industrial vibration monitoring. It accepts raw probe signals and delivers buffered -Vout and 4-20mA outputs to your monitoring system.
This industrial automation unit operates from -17.5Vdc to -26Vdc with excellent RF immunity. It supports both DIN rail and panel mounting without external isolation plates.

Quality Control Process
We validate every BENTLY 330980-51-00 before it ships. First, we verify power supply rejection using a programmable DC source. Output must remain stable across the full -17.5Vdc to -26Vdc range.
Next, we inject a calibrated RF signal to test immunity. The 330980-51-00 must reject interference without output spikes. We also verify 4-20mA loop accuracy with a precision process calibrator.
Finally, each replacement module ships in anti-static shielding with desiccant. This prevents moisture damage during transit.

Replacement Pitfall Guide
❗ Sensitivity Mismatch: The “-51” code dictates 100mV/mil sensitivity. Installing a 200mV/mil proximitors with an 8mm probe will double your vibration readings and cause false trips.
❗ Power Polarity: This unit requires negative DC power. Reversing polarity destroys the internal FETs instantly. Double-check your power supply wiring before energizing.
❗ Grounding Strategy: The mounting base is electrically isolated. Do not assume chassis ground. Connect the shield drain wire to the proximitors ground terminal only.
❗ Cable Length Limits: Total system length (probe + extension) must match the proximitors calibration. Swapping a 5m system for a 9m system without recalibration ruins linearity.
Keep these in mind and you’ll cut 90% of rework time.
