Level controller, RG 210 53206

Level controller based on PTC thermistor with selectable functions. Can be used in fuel oil, diesel, non-aggressive media and other non-conductive liquids that are not viscous or adhesive.

Level switch with 1 probe:
The relay switches in case of contact or loss of contact with the liquid. When the switch point is set, it must be observed that the PTC thermistor requires approx. 30 to 60 seconds to heat up depending on the ambient temperature.

Level control for filling with 2 probes:
Set internal switch to "FILL". The relay energises after the min. probe has heated up. Relay de-energises when the max. probe comes into contact with the liquid.

Level control for emptying with 2 probes:
Set internal switch to "EMPTY". Relay energises when max. probe has contact with the liquid. Relay de-energises when the min. probe loses contact with the liquid and heats up.

Please note:
Do not use as an overfill prevention system according to TRbF. Requires either the connection of an overflow pipe to the tank or the additonal installation of an overfill prevention system according to TRbF / WHG. You can use NB 220 QS and level detector 76A.
