Protec Liquid Level Controls
Protec conductivity level controllers use the principle of conducting a small AC current between probes in contact with solution. If the current circuit is completed, the solution must be at a level above two of the probes. To add another set point, an additional probe is used.
Protec liquid level controls are used to monitor the solution level within tanks and provide relay signals when condition points are reached. Commonly used to add additional solution to a tank to make up for evaporation or as a safety shutoff for a heater if the solution is to fall below a critical level. These controllers are adaptable to monitoring and controlling numerous levels within a tank with the addition of multiple probes.
A two probe level controller is required as a safety shutoff for electric immersion heaters.
