21504-000-036-10-02 is a 5mm Proximity Sensor Probe manufactured by Bently Nevada and used in Proximity Transducer System. The Proximity Transducer System and Sensors of the 3300 XL series work with replaceable probes of different lengths, armor, and connectors made by Bently Nevada.

Functional Description

Operating on the eddy current principle, the proximity probe senses the distance between the probe tip and the observed surface. The Proximitor generates a radio frequency signal, which is radiated through the probe tip into the observed surface. Eddy currents are generated in the surface, and the loss of strength in the return signal is detected by the Proximitor, which conditions the signal for linear display on a monitor.


  • There are five 11 mm versions and three 14 mm combinations available to satisfy both English and metric thread specifications.
  • The 11 mm fiberglass probes are constructed. The 14 mm probes are made of a high-performance plastic that can survive conditions that are unusually harsh, moist, and/or chemical.
  • Both transducers feature a scale factor of 100 mV/mil (4 V/mm) and can be used in small spaces.


  • Armored and Unarmored Options
  • Multiple Connector Options
  • Complete Interchangeability of Units and Cabling
  • Compact Form Factor
  • -18 to -24VDC VT
  • Wide Temperature Range: -55°C to 100°C
  • 11mm Probe Diameter

What sensor measures proximity?

Proximity sensors come in a variety of varieties. These include the magnetic sensor, inductive sensor, capacitive sensor, ultrasonic sensor, and photoelectric sensor.

How does a Bently Nevada probe work?

Proximity transducers measure the distance between the probe tip and the surface to be studied using the Eddy Current concept.

Is a proximity sensor digital or analog?

A proximity sensors output stage can be either analog or digital.

What does a proximity sensor produce?

A widely used variety of voltage proximity sensors is the inductive type. Depending on the distance between the target and the sensor, they detect objects and typically generate a 0–10 VDC output.
