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
