Description：

The 3300 5 mm Proximity Transducer System consists of:

a 3300 5 mm probe 12

a 3300 XL extension cable (ref 141194-01)

a 3300 XL Proximitor Sensor 3,4,5 (ref 141194-01)

When combined with a 3300 XL Proximitor Sensor and XLextension cable, the system provides an output voltage thatis directly proportional to the distance between the probe tipand the observed conductive surface. The system canmeasure both static (position) and dynamic (vibration) data.Its primary use is in vibration and position measurementapplications on fluid-film bearing machines, as well asKeyphasor measurement and speed measurementapplications6.

The system provides an accurate, stable signal output over awide temperature range. All 3300 XL Proximity TransducerSystems achieve this level of performance with completeinterchangeability of probe, extension cable, and Proximitorsensor, eliminating the need for individual componentmatching or bench calibration.

Frequently asked questions

Q1: What is the Bently Nevada 330173-00-04-20-12-05 Proximity Probe used for?

A1: The Bently Nevada 330173-00-04-20-12-05 Proximity Probe is a non-contact sensor used for monitoring shaft vibration, axial position, eccentricity, runout, and displacement in rotating machinery. It is widely used in machinery protection and condition monitoring systems.

Q2: What does Overall Case Length Option (04) indicate?

A2: The 330173-00-04-20-12-05 Overall Case Length Option (04) specifies a probe case length of 40 mm, making it suitable for installations with limited mounting space.

Q3: What does Total Length Option (20) represent?

A3: The 330173-00-04-20-12-05 Total Length Option (20) indicates a total cable length of 2.0 metres (6.6 feet).

Q4: What is the recommended gap setting for the 330173-00-04-20-12-05 probe?

A4: The 330173-00-04-20-12-05 recommended installation gap is 1.27 mm (50 mils), which helps ensure optimal measurement accuracy and linear output.

Q5: What is the 330173-00-04-20-12-05 incremental scale factor?

A5: The 330173-00-04-20-12-05 probe provides an incremental scale factor of 7.87 V/mm (200 mV/mil) ±6.5%, delivering a linear output proportional to the distance between the probe tip and the target surface.
