Besta BLS 30 ATEX Level Sensor

This BLS 30 Trimod’Besta Level Sensor with I.S barrier included, is ATEX approved for Ex ia IIC T5, ATEX II 1G (Gas) and universally suitable for level detection and a real alternative to the tuning fork. It works in liquids of all kind, foams, bulk goods, granulates, even in liquids that are sticky, pasty and regardless of their viscosity.

On-site calibration is not necessary and the highly accurate sensor can be installed in any position. It has a very attractive, compact design and is completely maintenance free. Powered via an M12 connector it communicates its output status through a highly visible blue LED.
