Vibration Switch

Electronic Vibration Switch is designed as a direct replacement of mechanical vibration switches. The mechanical switches used earlier had very little merit and served the purpose when the requirement was not stringent. As they relied on large impacts of inertia (both acceleration) nuisance tripping during start-up was a 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 relay takes care of startup and other spurious signals. Remote reset is another positive advantage. Either ‘standalone’ or ‘remote sensor’ option is 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 application areas are cooling towers, centrifuges, large motors and generators, compressors, crushers, naval vessels, etc.
