Product Details

Level Sensing Relay

Dual voltage sensing relay 115/230V AC
Single or two point level control
Selectable 'Pump-up' or 'Pump-down' modes
Variable sensitivity; 2kΩ on, 5kΩ off, to 20kΩ on, 50kΩ off
LED indication of relay and supply status
Panel cutout (mm): 45 x 45
Single point level; relay energises (Pump-up) / de-energises (Pump-down) when liquid level drops below the set level electrode
Two point level; relay energises when liquid level drops below low level electrode and de-energises when level reaches high level electrode (Pump-up)
Relay de-energises when liquid level drops below low level electrode and energises when level reaches high level electrode (Pump-down)


Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use.
