REOVIB SWM 843
The REOVIB SWM 843 monitoring units are intended for measuring and displaying the behaviour of vibrating chutes. The measured value can be read directly as acceleration, vibration, or frequency value on the unit's 5-digit, 7-segment display.
Furthermore, the measurement value is available as a proportional 0/4...20 mA output signal.
Chute vibration is detected by means of an acceleration sensor. The measured vibration value is compared with preset minimum and maximum limit values. If either limit is exceeded, the corresponding alarm relay is triggered after an adjustable response delay time has elapsed, thus signalling a fault in the feeder chute.
To prevent incorrect measurements during feeder start-up, operation of the unit can be delayed for an adjustable period after the mains supply has been switched on.
