Infrared fork sensors for fluid detection

20 September 2012

Balluff has extended its range of BGL fork sensors by offering a fluid detection sensor. This infrared fork sensor is suitable for detecting the level of clear, coloured or turbid fluids with a water content >15% through transparent walls. Fluids such as milk, household cleaners, viscous detergents, ketchup etc. cause no problem for this compact sensor.

Applications that would normally cause problems for ultrasonic or standard capacitive sensors are ideal for the BGL Fork Sensors. Detecting fluids in small transparent hoses with a diameter of 6mm or smaller is no problem. Thin residues that adhere to the container wall (up to a thickness of 0.5mm) can be compensated by using the sensitivity setting of the potentiometer.

Available with fork openings of 30mm and 80mm, these compact sensors are housed in a rugged IP67 rated metal enclosure. The sensors have a switching frequency of 2 KHz and are available with NPN or PNP output.

The BGL Fork Sensor has 3-pin M8 connection and standard through-holes for mounting. Custom made bracketry solutions are no longer required, with a sensor holder available from the new Balluff BMS universal mounting system.
