PCB Piezotronics - PRODUCT NEWS



PCB Piezotronics, a world leader in vibration, acoustic, pressure, force and torque sensors, has announced that its unique 686B01 series vibration switch has been ATEX approved for use in hazardous environments.

The EX686B01 is ideal 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 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 as it only requires two wires and can replace legacy switches without additional cable runs. 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, said: "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.
