IMI Sensors Receives Patent for "Linear Adjust" Mechanical Vibration Switch


DEPEW, NY — IMI Sensors, a PCB Piezotronics Division and manufacturer of industrial vibration monitoring instrumentation, such as accelerometers, vibration transmitters, and switches announced 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 in the table below:



Model                                    CSA/UL Approval                                 Remote Reset



685A08                                    Yes                                                             No

685A09                                    No                                                               No

685A19                                    No                                                               Yes (+/- 24 VDC)

685A29                                    No                                                               Yes (120 VAC)

685A39                                    No                                                               Yes (240 VAC)



IMI offers other vibration switches, including 4-20 mA electronic switches (685B Series) and USB-programmable smart switches (686B Series).
