Sensor The sensor used in the OPTISYS SLM 2100 is a suspended solid sensor. The sensor contains a near-infrared light source and a receiver in an angle of 180°. Both are positioned in such a way that the emitted near-infrared light has to pass through the liquid before reaching the receiver.
The cleaning unit, mounted under the device, consists of a valve and a spraying system to keep the sensor and cable free of deposits ensuring low maintenance efforts of OPTISYS SLM 2100. The cleaning unit uses water which can be supplied either by an external water source (process water) or by water from the clear water phase.
Due to the weight above 20 kg / 44.1 lbs please lift and carry the device only with two persons or use appropriate lifting equipment and if the surfaces of the device are wet, please use gloves for lifting. 01/2017 - 4002737304 - MA OPTISYS SLM 2100 R04 en www.krohne.com...
