PR6423/008-110+CON041 electric sensor

A voltage signal proportional to the vibration velocity can be provided. The two families of sensors are available in several basic models and are widely used in many fields of industrial measurement. Rugged construction allows installation in hazardous environments. It can be used in various turbo-machinery, fan, compressor, gear box, water pump, coal research machine, etc. Sensors PR 9268/60 and PR 9268/70 are especially suitable for high temperature environments. This sensor has three different sensitivities, depending on the type of measuring amplifier. The high output and low impedance of the measuring coil make the sensor have strong anti-interference. It can be directly connected with epro’s MMS 3000 and MMS 6000 turbine monitoring and protection systems. How it works: The vibration sensors PR9266 and PR9268 consist of a seismic block and a measuring coil supported by a spring plate.

The measuring element can be moved in the magnetic field of a circular magnet. The natural frequency of the sensor ranges from 4 to 13Hz, depending on the sensor model. The sensor housing vibrates, generating a voltage signal proportional to the vibration speed. PR9268 /… Series sensors can only have one measurement direction (vertical or horizontal). PR 9266/.. The series sensor has a lifting coil that can be used for both vertical and horizontal measurements. German EPRO (Philips) PR9268 series electric sensor.
