Balluff valve transducer achieves IECEx rating for hazardous areas
February 23, 2012 - Balluff’s Micropulse TA12 explosion-proof linear position transducer now has IECEx hazardous area approval rating, in addition to existing ATEX and North American approvals, for use in applications where hazardous gases and/or dusts are present.
The Micropulse TA12 is a non-contact linear position sensor with a compact, explosion proof housing. It’s specifically designed for continuous feedback on hydraulically and pneumatically actuated valves for oil and gas refining, storage, transport, and handling. The magnetostrictive sensor is designed for both extended duty and quick replacement – key attributes in the busy energy sector.
Non-contact, wear-free magnetostrictive technology ensures long life and MTBF for maximum production uptime. In the rare instance where the unit does require service, the TA12 incorporates its electronics and sensing hardware in a Rapid Replacement Module (RRM) that allows fast field repairs by the customer. With the RRM, there is no need to break the hydraulic seal. This eliminates fluid spillage and the need to bleed air from the hydraulic system after repair. The Balluff Rapid Replacement Module allows a user to get production up and running quickly in the unlikely event repair is ever necessary.
The Micropulse TA12 offers a wide array of control signal interface options, including analog voltage and current, start/stop pulse digital, synchronous serial digital, digital quadrature, and digital field buses such as Profibus and CANbus.
The International Electrotechnical Commission (IEC) established the IECEx system to certify equipment for operation in explosive atmospheres. This system facilitates international trade while maintaining required safety levels.
