1500 Induction Style Control Relay
A floatless liquid level control system from B/W Controls consists of a relay of the proper type, a holder designed to support one or more electrodes or probes in the liquid container, and the corrosion resistant electrodes themselves.
We manufacture the high quality Model 1500 induction relay under the brand B/W Controls.
The B/W Controls 1500 induction relay utilizes the liquid as an electrical conductor to complete the secondary circuit between the upper and lower electrodes.
Thus, when the liquid contacts the upper electrode, the resulting flow of current in this circuit sets up a bucking action in the lower bar of the core. This action tends to divert lines of magnetic force to the core legs and sets up an attraction that pulls the armature in to contact with the legs. This armature movement closes the electrode and load contacts.
