The 129716-173-037-15-05 is a 3300 XL 8mm eddy current preamplifier manufactured by Bently Nevada, USA. This device serves as the core processing unit of a non-contact measurement system, responsible for monitoring and providing high-frequency oscillation signals, and converting the measured eddy current changes into a signal voltage.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
The 3300 XL 8 mm Proximity Transducer System has a 7.87 V/mm (200 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The 129716-173-037-15-05 Proximitor Sensor features the advanced technology of the 3300 XL 8 mm series. Its thin structure allows it to be mounted in either a high-density DIN-rail installation or a more traditional panel mount configuration.
Improved RFI/EMI immunity allows the 3300 XL Proximitor Sensor to achieve European CE mark approvals without any special mounting considerations. This RFI immunity also prevents the transducer system from being adversely affected by nearby high-frequency radio signals. SpringLoc terminal strips on the Proximitor Sensor require no special installation tools and facilitate faster, highly robust field wiring connections.

When using the 129716-173-037-15-05 Proximitor Sensor, it is critical to ensure that the physical connections of the extension cable, probe, and Proximitor form a strict 9.0-meter total system length, as mismatched lengths will cause significant measurement errors. During installation, the integrated isolated base must be used to maintain electrical insulation between the Proximitor housing and the DIN rail. Field wiring must be secured tightly via the SpringLoc terminals, and approved safety barriers must be installed when routing signals into hazardous areas.
This specific model is configured for a 9.0-meter total system length and functions within an ambient temperature range from -51°C to +100°C. Operating over a 2.0 mm span, this unit converts eddy current signals into precise data for radial vibration, radial position, axial (thrust) position, tachometer, zero speed, and phase reference (Keyphasor) signals. Backed by worldwide intrinsic safety approvals, it is fully authorized for continuous monitoring within hazardous industrial environments.
It is a Proximitor Sensor (transducer module) that provides a high-frequency oscillation signal to the probe and converts eddy current variations into a proportional voltage output.
How does 129716-173-037-15-05 work?
It generates an alternating magnetic field at the probe tip via a radio frequency (RF) signal. As a metallic shaft surface approaches, eddy currents are induced, and the Proximitor measures this energy loss to calculate distance.
What is the primary industrial application of 129716-173-037-15-05?
It is primarily used to measure shaft vibration (X-Y), axial displacement (thrust), and shaft speed/keyphasor on large rotating machinery.
How should 129716-173-037-15-05 be used?
It must be snapped onto a DIN rail inside a housing panel, connected to a 3300 XL 8mm probe and extension cable (total system length must match 9m) on one side, and wired to the monitoring system on the other.
What should be noted if using 129716-173-037-15-05 in hazardous areas?
Since it carries the "05" intrinsic safety approval, it must be connected through an approved Intrinsic Safety Barrier when entering a hazardous zone to limit electrical energy.
