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
Note
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
Approvals
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
