ELECTRONIC VIBRATION SWITCH IS DESIGNED AS DIRECT REPLACEMENT OF MECHANICAL VIBRATION SWITCHES.

THESE MECHANICAL SWITCHES BEING USED IN YESTER YEARS HAVE VERY LITTLE MERIT AND SERVED THE PURPOSE
WHEN THE REQUIREMENT WAS NOT STRINGENT. AS THEY RELY ON LARGE IMPACTS OR INERTIA (BOTH ACCELERATION) AND DOES NOT RESPOND TO GRADUAL INCREASE IN VIBRATIONS. NUISANCE TRIPPING DURING START-UP IS AN USUAL  PROBLEM. FURTHER, SENSITIVITY ADJUSTMENT IS TOO AMBIGUOUS TO OFFER ANY MEANINGFUL TRANSLATION.

ACD VIBRATION SWITCHES CAN BE DIRECTLY INSTALLED IN PLACE OF MECHANICAL VIBRATION SWITCHES AND OFFER IMMENSE ADVANTAGES. THE BASIC SENSOR IS PIEZO ELECTRIC ACCELEROMETER WHICH HAS NO MOVING PARTS. THESE ELECTRONICALLY INTEGRATE THE ACCELERATION SIGNAL GIVING DISPLACEMENT OR VELOCITY SIGNAL  AS PER REQUIREMENT. VIBRATION COULD BE CONTROLLED VERY PRECISELY WITH GRADUATED CONTROLS. BUILT IN ELECTRONIC DELAY TAKES CARE OF STARTUP AND OTHER SPURIOUS SIGNALS. REMOTE RESET IS ANOTHER POSITIVE ADVANTAGE.

EITHER ‘STAND ALONE’ OR ‘REMOTE SENSOR’ OPTIONS ARE AVAILABLE

THESE SWITCHES CAN BE SUPPLIED IN ENCLOSURES FOR WEATHER PROOF (IP 65) APPLICATION OR FOR GAS AREAS IIA - IIB (CLASS I, DVN I GRP. C&D) OR IIC (CLASS I, DVN II, GRP B)

SOME OF THE APPLICATIONS ARE COOLING TOWERS, CENTRIFUGES, LARGE MOTORS AND GENERATORS,
COMPRESSORS, CRUSHERS, NAVAL VESSELS ETC.
