Composition of sensor

The sensor is generally composed of four parts: sensing element, conversion element, conversion circuit and auxiliary power supply.

The sensing element directly senses the measured and outputs the physical quantity signal that has a definite relationship with the measured; The conversion element converts the physical quantity signal output of the sensor into an electrical signal; The conversion circuit is responsible for amplifying and modulating the electrical signal output by the conversion element. Conversion elements and conversion circuits generally require auxiliary power supply.

EPRO.PR6423 series electrodynamic sensors Germany EPROPR6423 (Philips) PR9268 series electrodynamic sensors for vibration measurement; Operating temperature up to 200℃; Easy to install; High sensitivity; Rugged housing for industrial applications; Waterproof protection class: IP 55 resp. IP 65; Two frequency ranges: 10 HZ-1000 Hz; 4 HZ-1000 Hz; Connection Safety fence (zone 1) Explosion-proof class EEx ib II B/II C; It is part of the MMS 6000 and MMS 3000 rotating machinery monitoring and protection systems. Application: Vibration sensor PR9266/… And PR 9268/… Series for measuring frequency range 10… 1000Hz and 4… 1000Hz mechanical vibration. The maximum amplitude of the measurement can reach 2mm and some can reach 3mm (peak-peak). A voltage signal proportional to the vibration speed can be provided. Both series of sensors are available in several basic models and are widely used in many areas of industrial measurement. Rugged construction allows installation in hazardous environments. It can be used in various turbo-machines, fans, compressors, gear boxes, water pumps, coal ladders and so on.

The sensors PR 9268/60 and PR 9268/70 are particularly suitable for high temperature environments. This sensor has three different sensitivities, depending on the type of measurement amplifier. The high output and low impedance of the measuring coil make the sensor have strong anti-interference. It can be directly connected to the epro 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, producing a voltage signal that is proportional to the vibration speed. PR9268/… Series sensors can only have one measurement direction (vertical or horizontal). PR 9266/.. The series sensor has a lift coil that can be used for both vertical and horizontal measurements. German EPRO (Philips) PR9268 series of electric sensors.
