ATEX-approved smart vibration switch for machine monitoring
PCB Piezotronics' 686B01 series vibration switch is now ATEX-approved for use in hazardous environments. The EX686B01 is suitable for 24/7 continuous protection of cooling tower fans and gearboxes, fin fans, motors and pumps, HVAC systems, wind turbines and other critical machinery operated in hazardous areas. Meeting ATEX Ex nL IIC T3 approval requirements for use in hazardous environments, the EX686B01 is hermetically sealed and mounts with a single stud like a sensor. This smart vibration switch includes an embedded piezoelectric accelerometer for accurate measurement and monitors vibration velocity for more consistent results. Delivering reliability that the company claims cannot be matched by mechanical switches, the EX686B01 also offers a remote reset capability and USB programmable alarm threshold and time delays to avoid false trips.
PCB Piezotronics' EX686B01 is highly versatile, fully user-programmable via USB, and is a low-cost drop-in replacement for most popular mechanical vibration switches because it only requires two wires. In addition to being a more reliable device compared to mechanical vibration switches, the EX686B01 is also a significantly lower-cost alternative for many electronic vibration switch applications requiring single relay operation.
Commenting on the approval, Graham Turgoose, PCB Piezotronics' UK managing director, says: "We are very pleased that the 686B01 has been ATEX-approved for hazardous area use, as many of the application enquiries we have received for this unique switch have required the certification. We are confident that this product will now become an industry standard for use in monitoring equipment used in hazardous environments."
All standard PCB sensors are supplied with Lifetime Warranty Plus and are also covered by the company's Guarantee of Total Customer Satisfaction. Contact PCB Piezotronics or follow the link for more information about the ATEX-approved 686B01 series smart vibration switch.
