Balluff expertise in the Ex area - Sensors and transducers with international approval

14 January 2016

In explosive atmospheres, only devices with Ex approval may be used. This also applies to sensors and position measurement systems used as position feedback systems in settings such as the oil and gas industry, power plants or in hazardous factory automation areas. Customers seeking a suitable solution for their applications will quickly find what they need from the sensor specialist Balluff. 

Balluff boasts a portfolio of contact-free measuring, magnetostrictive Micropulse transducers and sensors in a multitude of designs for various Ex zones.

Micropulse transducers are one of the few transducers on the market to feature not only all basic certifications such as ATEX (EU), IECEx (international), NEC (US) and CEC (Canada), but also additional regional approvals from countries including India, Japan and Korea. Not only does this simplify the design and global sale of standardized systems, it also helps to prevent expensive errors in the project planning phase.

One product from the portfolio is the new Micropulse transducer BTL7-… for various Ex zones. Its application areas include the monitoring of hydraulic and pneumatic cylinders, inspection of hydraulically controlled valves and the detection of fill levels. Its highly compact design and array of convenient features put it a step ahead of comparable solutions. One of these features is a configuration function via a cable.

Inductive sensors BES and high-pressure resistant inductive sensors BHS complete the Ex portfolio (oil pressure resistant up to 500 bar). Their preferred areas of application include final position control for hydraulic cylinders and valve position monitoring.
