LEVEL
Warrick Conductivity Controls provide a dependable, no-moving-parts control and monitoring of conductive liquids. Conductivity controls offer reliability, process automation, labour savings, flexibility and operator safety at economical cost. Take advantage of a liquid’s conductive properties to complete a circuit and cause a control relay to actuate. The use of permanently mounted stationary electrodes gives the user precise accuracy, repeatability and no-moving-parts reliability.
Control/Relay – An electrical device with contacts that open and close in response to liquid levels sensed by the probes. Because it is wired directly to the power source and the sensing source, it can send signals that activate or deactivate solenoids, pumps, alarms or pressure switch devices.
Fitting – Housing that holds the probes (or floats), insulates them from the vessel, and provides a means of connection to the control. Warrick® fittings are available for single-probe or multi-probe applications, for mounting to vessels in a variety of ways, and in open or pressure tight styles.
Probe – A sensor that extends downward from the fitting, with the tip positioned precisely at the level where the control should be activated. Stainless steel electrodes can be cut to the desired length.
Gems/Warrick conductivity controls provide alarm, pump-up or pump-down control in electrically conductive liquid.
