Patent ID: 11654315

Abstract:
An extinguishing-agent discharge device includes a casing having a guide channel for an extinguishing agent, a metallic handle, a hose connection, an adjustment means for regulating an extinguishing-agent supply using a manual control unit and a discharge nozzle. A measuring-current transformer generates a current signal proportional to the electric current flowing in the extinguishing agent; an insulator section divides the casing into a discharge area having the discharge nozzle and an inlet area having the manual control unit, the measuring-current transformer disposed in the insulator section; a first electrode disposed in the discharge area in the extinguishing-agent flow and serves for detecting an extinguishing-agent potential; a second electrode disposed at the handle for detecting a ground potential in the inlet area; and a controller for evaluating the current signal for a potential difference occurring between the extinguishing-agent and ground and having a drive element acting on the adjustment means.
