IMI Sensors: A PCB Piezotronics Division Mechanical Vibration Switch The new patent pending design innovation provides better control over trip sensitivity than any other mechanical vibration switch on the market Highlights n n Low cost protection for critical machinery Outperforms traditional mechanical vibration switches Linear trip adjustment (~1/4 turn per g) Better sensitivity repeatability on reset DPDT relay, 15 amp dry contacts 120, 240 VAC or 24 VDC remote reset options Cooling towers HVAC systems Motors & pumps Blowers Fin fans Large exhaust and vent fans 24/7 protection IMI Sensors has developed this new mechanical vibration switch, Model 685A09, which not only effectively competes in the mechanical vibration switch market but also has a significant technical advantage. This Linear Adjust Mechanical Vibration Switch has a unique new design that provides much better sensitivity adjustment than traditional designs. This allows a user to better control the trip level in the switch and improve protection of their equipment (reference test data below). Additionally, due to the design and manufacturing processes used to build the switch, it is more cost competitive than any of the existing mechanical vibration switches on the market, including pricing advantage in the OEM market.
