Product Overview
The Bently Nevada 144181-50 is a 3300 XL Proximitor Sensor for 5 mm and 8 mm probe systems.
It converts the eddy current field detected by the probe into a proportional voltage signal (7.87 V/mm or 200 mV/mil), representing the gap between probe tip and target.
The 3300 XL series allows total interchangeability, so the sensor works with any compatible 3300 XL probe and extension cable without individual calibration.
It is ideal for vibration and position monitoring on fluid-film bearing machinery such as gas turbines and large compressors.

Keyphasor® & Speed Measurement: Provide once-per-rev pulses for timing and speed.
-
Machine Casing Expansion: Monitor thermal growth to maintain safe clearances.
System Functions and Experience
-
High RFI/EMI immunity allows installation in fiberglass or plastic housings.
-
Provides stable baseline and temperature stability, improving monitoring of older systems.
-
SpringLoc terminals enable faster, secure wiring compared to screw-type terminals.
-
Ensures accurate, repeatable data for 3500 series monitors and automated safety trips.
FAQ
Q1: Is the 144181-50 compatible with older 3300 series (non-XL) probes?
A1: Yes. It is backward compatible, but performance is limited to the older hardware.
Q2: Does this sensor require a separate isolator plate for mounting?
A2: No. The mounting base provides built-in electrical isolation, simplifying installation.
Q3: What happens if the probe-to-target gap is outside the linear range?
A3: Output voltage becomes non-linear or flatlines, usually triggering a "NOT OK" status. Set initial gap near the center of the range (-10 VDC).
Q4: Can this sensor be used in hazardous areas?
A4: Yes, when used with intrinsically safe (IS) barriers or galvanic isolators. Check product label for ATEX or CSA approvals.
