Broyce Control Level Controller DIN Rail Mount, 110 V ac 1 Input
Product Details

Liquid Level Controller, Plug In Base

Controls maximum and/or minimum levels of conductive liquids
’Pump-up’ or ’Pump-down’ modes selectable via switch
Adjustable sensitivity, 5 to 100kΩ
One or two probe operation
Low voltage, ac current across probes prevents electrolysis phenomena
Ambient temperature; -20 to + 60°C
Dimensions; H89mm x W40mm, x D92mm


1. If using metal tank, connect “pin 1” and earth to the tank
2. If supply is interrupted for ≤0.5s in “pump-up” mode, the relay will energise immediately.
In “pump-down” mode relay remains de-energised
3. For single probe operation, link terminals “pin 1” and “pin 7”


UL recognised component for Canada and US

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.

Application Examples

Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the:

Monitoring and control of liquid levels
Protection of pumps against dry running
Ability to detect liquid leaks in a system
Control of media mixing ratios
Control of liquid levels
