Floatless Level Control
Probemaster, the most accurate, dependable and economical level control for water systems. Conductive probes with no moving parts in water. The probe conducts a minute current through the water to operate the Probemaster The probe control operates on low voltage with current in the low micro-ampere range. Standard sensitivity is 50,000 ohms. Because of the low voltage and current the probes are safe to handle when powered. Two probes and ground provide a differential operation. The operation can be ON at one level, and OFF at another level. The Probemaster is available in pump up or pump down models. With loss of power both models provide open output contacts for failsafe operation.
