The BLCSM level switch, consists of a double-chamber plastic housing and a micro switch inside. The double-chamber construction and a final remolding make the switch absolutely hermetic. Switching differential can be set by means of a counter weight that can be adjusted alongside the cable of the switch. The high contact load allows the BLCSM model to switch directly pumps or other single-phase actuator devices up to 3.7 kW or 2.0 kVA. The length of the sensor cable, which is made of PVC or Neoprene, can be ordered up to 20 meters. The BLCSM level switch is suitable for liquids with density down to 0.8 g/cm3. Thanks to its non-toxic body materials and mercury-free micro switch, BLCSM is ideally applicable for drinking water control. Some practical applications include: – vessel emptying control; – vessel filling control; – pump protection.
