Product Information

Bently Nevada 330195-02-12-50-00 is a 3300 XL 8 mm Extended Temperature Range reverse-mount proximity probe with a 3/8-24 UNF thread. It senses the gap to a conductive target and operates with the extension cable and Proximitor Sensor of a 5.0 m transducer system.

Reverse mounting defines the mechanical arrangement of Bently Nevada 330195-02-12-50-00: the probe body enters from the rear of the mounting surface and the fixed 02-12 geometry establishes the case and shoulder relationship. This orientation leaves the sensing tip facing the target while the cable exits on the accessible side of the bracket.

The conditioned response of Bently Nevada 330195-02-12-50-00 uses the 2.0 mm linear range, 7.87 V/mm scale factor and 1.27 mm recommended gap of the 3300 XL 8 mm system. The ETR construction applies to the probe-side assembly, while the `50` field identifies the complete 5.0 m electrical length.

Installation

The reverse-mount construction of Bently Nevada 330195-02-12-50-00 controls the direction of insertion, the location of the shoulder and the way the cable leaves the mounting surface.

Rear-entry geometry

The probe enters from behind the bracket rather than through the target-facing side. The mounting surface therefore supports the probe body while the sensing tip remains directed toward the shaft or target.

Fixed mechanical record

The 02-12 fields define the supplied reverse-mount geometry as one complete mechanical arrangement. The shoulder, threaded section and available case length work together to establish the installed position.

Cable-side access

The integral lead exits on the rear side of the mount with the probe body. This arrangement keeps the connection and cable path on the accessible side while the tip remains in the measurement location.

Monitoring and Control

Once connected as a 5.0 m 3300 XL system, Bently Nevada 330195-02-12-50-00 supplies a conditioned voltage that represents target movement within the calibrated linear region.

Gap-to-voltage conversion

Movement of the conductive target changes the probe field and the Proximitor Sensor output. The 7.87 V/mm scale factor defines the relationship within the stated 2.0 mm linear range.

Centered operating point

The 1.27 mm recommended gap places the signal near -9 VDC. That operating point leaves usable measurement travel for motion toward and away from the probe tip.

Five-metre system path

The `50` field identifies the total 5.0 m transducer system. Probe, extension cable and Proximitor Sensor lengths are treated as one calibrated signal path.

Questions & Answers

Bently Nevada 330195-02-12-50-00: Why can the probe tip reach the target while the body still does not seat correctly?

Bently Nevada 330195-02-12-50-00 requires this check: Check the rear-entry shoulder and fixed 02-12 reverse-mount geometry; tip reach alone does not prove that the mounting surface is supporting the body in the intended position.

What causes a correct mechanical gap to produce the wrong bias voltage on Bently Nevada 330195-02-12-50-00?

For Bently Nevada 330195-02-12-50-00, confirm that the probe, extension cable and Proximitor Sensor form the 5.0 m system identified by the `50` field before changing the mechanical position.

When Bently Nevada 330195-02-12-50-00 is involved, how can a customer distinguish this probe from a front-mount 8 mm probe?

The correct approach for Bently Nevada 330195-02-12-50-00: Verify the complete 330195 reverse-mount identity and compare the rear-entry body and shoulder arrangement rather than relying only on the common 3/8-24 thread.

For Bently Nevada 330195-02-12-50-00, what should be checked when the signal reaches the end of its range during shaft motion?

With Bently Nevada 330195-02-12-50-00, verify that the operating point is near the recommended 1.27 mm gap and that target motion remains inside the 2.0 mm calibrated linear region.

Why is the cable side kept behind the mounting surface when working with Bently Nevada 330195-02-12-50-00?

The reverse-mount body places the lead and connection on the rear side while the sensing tip faces the target, which is the defining geometry of this configuration. This boundary applies to Bently Nevada 330195-02-12-50-00.

Bently Nevada 330195-02-12-50-00 troubleshooting: can a probe with the same thread but another total length use the existing signal chain?

On Bently Nevada 330195-02-12-50-00, the 3/8-24 thread only describes mechanical fit; the complete 5.0 m electrical length must also match the extension cable and Proximitor Sensor.
