Bently Nevada 330780-90-05 Proximitor Sensor
Brand: Bently Nevada
Module: 330780-90-05
Description: Proximitor Sensor
Country: USA
The Bently Proximitor Sensor is an eddy-current proximity displacement sensor that provides direct observation of shaft or target displacement measured by a variety of vibration, displacement, rotational speed and time (such as phase) measurements. These sensors are available in a wide range of end diameters and thread sizes, ranging from 200 microinches to 1 inch (commonly used for differential expansion measurements in large steam turbines), including the 80 meter range suitable for most machine measurements.
The working principle of the Bently Proximitor Sensor is that when a coil at the top of the probe is attached with a high-frequency current and is close to a conductive surface, eddy currents are generated on the surface of the conductive object due to the action of the magnetic field line of the coil, thus reducing the inductance of the coil. This change in coil characteristics is converted into a DC voltage signal output. The approach sensor system uses a scale factor to convert the system output into a displacement value.
