DEPEW, NY - IMI Sensors, a PCB Piezotronics Division and manufacturer of industrial vibration monitoring instrumentation, such as accelerometers, vibration transmitters, and switches announces the receipt of U.S. Patent No. 9,024,712 from the U.S. Patent and Trademark Office (USPTO) on its 685A-Series "Linear Adjust" Mechanical Vibration Switch.
The innovative "Linear Adjust" perpendicular magnet-mass design provides more precise sensitivity adjustments (approximately ¼ turn per g) and more consistent sensitivity over all three axes when compared to competitive models based on the parallel magnet-mass design.
The mechanical vibration switches are used in applications such as cooling towers, HVAC systems, motors & pumps, blowers, fin fans and large exhaust and vent fans.
The switch is available in five stocked models as listed below:
