Brüel & Kjær Vibro │ Instructions Sensor ds822 2 mm Assembling the displacement sensor 4.1.1 Displacement sensor for front-side mounting The front side-mountable displacement sensors are supplied with two nuts. You can use these nuts to lock it in place after adjustment (4.4 Setting up the measuring chain and the displacement sensor). Depending on the application, the sensor can be mounted forward-facing either within a machine or outside of a machine or through the machine housing. -
Page 16: Assembling The Driver (Oscillator/Demodulator)
Assembling the driver (oscillator/demodulator) Assemble either: • with assembly adapter on a hat-rail • with assembly adapter via screw mounting on a firm surface The driver must be mounted electrically insulated on its mounting socket and inside a protective housing, because the driver housing is part of the instrinsically safe circuit. The distance of the driver housing to adjacent drivers, or any other conductive part of the housing, must always be above 2 mm. -
