Besta BLS frequency sweep level switch

Click2Contact

The Besta BLS frequency sweep level switch offers a compact alternative to vibrating tuning forks.

A single sensor will detect a wide range of different applications including bulk goods/grains and liquids (high or low viscosity) - even with sticky or pasty media. Typical installations include petrochemical, pharmaceutical, food and beverage and general industry (for lubricants and coolants).

With no moving parts, this rugged design sensor is immune to shock and vibration (IEC 60068-2-6, GL test 2). It can be mounted in any orientation under tough process conditions (-40 to 115°C, up to 100 bar) and is immune to foams and suspended particles. The BLS has a fast reaction time of less than 100 ms, but can be factory set to include switch damping (0-10 s).
