LIQUID LEVEL CONTROL RELAYS
LCP Series Liquid Level Control Relays regulate levels of conductive liquids in pump up (fill) or pump down (drain) applications. The output of the relay controls pumps, solenoids, or valves to lower, raise or maintain the liquid level in the tank. Typical liquids include tap water, seawater, sewage, irrigation, chemical and pharmaceutical solutions, beer, coffee, and ice cream.
Precisely Raise, Lower or Maintain Conductive Fluid Levels
The probe is pulsed with DC voltage to prevent potential electroplating. An LED indicates energization status. Choose from two adjustable sensitivity ranges based on fluid. Mounting requires an industry standard 8 pin octal socket. Choose from Single Probe or Dual Probe configurations.
SINGLE PROBE
On single probe models a fixed time delay prevents rapid cycling of the output relay and its load. Ten factory settings ranging from 1 to 60 seconds.
DUAL PROBE
Dual probe models are available with specific pin configurations to match competitive devices.

Frequently Asked Questions About Liquid Level Control Relays
Macromatic relays specify the power consumed by the device as “burden” in units of VA. Look for the burden specification in the catalog page for the specific device you have. The unit of VA(volt-amps) is essentially the same as Watts(power), current draw can be calculated in Amps by taking the VA specification and dividing by the voltage control voltage you are using to power the device.
Level probes can be made from any conductive material. The head of a bolt through the sidewall or a threaded rod suspended from above are often used as probes with wires attached using ring terminals.
