The Bently Nevada Proximitor Sensor is a type of eddy current sensor used to measure rotor shaft position and vibration within the clearances of its fluid film bearings . They are known for their ruggedness, reliability, and superior performance in harsh environments, making them ideal for a wide range of applications in machinery condition monitoring.

Here's how Bently Nevada Proximitor Sensors work:

• The sensor uses a coil to generate an electromagnetic field.
• When the probe tip of the sensor comes close to a conductive surface, like the shaft of a rotating machine, eddy currents are induced in the surface.
• The eddy currents create their own electromagnetic field, which opposes the original field from the coil.
• The strength of the opposing field is proportional to the distance between the probe tip and the surface.
• By measuring the strength of the opposing field, the sensor can determine the position of the shaft.
• Bently Nevada Proximitor Sensors are typically used in conjunction with a Bently Nevada Proximitor System, which includes the sensor itself, a cable, and a signal conditioner. The signal conditioner converts the output of the sensor into a usable signal that can be used to monitor the condition of the machine.

• Accurate and reliable measurement of shaft position and vibration
• Rugged and durable construction for use in harsh environments
• Easy to install and maintain
• Compatible with a wide range of Bently Nevada Proximitor Systems
