Series 686B USB Programmable Smart Vibration Switch

Description

The IMI Sensors division of PCB Piezotronics (PCB®) has released Series 686B USB Programmable Smart Vibration Switch, designed for 24/7 continuous monitoring and protection of cooling towers, fin fans, pumps, HVAC systems, and other critical machinery.

Series 686B offers a smart alternative to unreliable mechanical switch technology. This electronic switch has much better accuracy and reliability than traditional mechanical switches, and is easily installed in place of existing mechanical switches, since it only requires two wires – and can replace legacy switches without the need for additional cable runs. Series 686B also offers a remote reset capability and USB programmable delays to avoid false trips. This universally powered unit is hermetically sealed for use in the harshest of environments, mounts with a single stud like a sensor, and is available for use in hazardous areas.
