PZ short-circuit probe to PZ-828 flood relay

Purpose The design of the probe allows it to be mounted on a flat horizontal surface, e.g. on the floor in a room with water valves, flow pipes or in a laundry room, which allows for quick detection of failures and flooding the room with liquid, while switching off electrical circuits or activating sound or light signaling (alarm ).The probe cable can be extended up to 100 m.Up to 10 probes can be connected to the 5-6 input (in series or in parallel): • in series - for a dependent fluid level control system at many points, all connected sensors must be short-circuited at the same time for the relay to operate; • in parallel - for an alternative fluid level monitoring system, multiple points must short-circuit at least one of any of the connected sensors.When connected in series, the sensitivity of the sensors is reduced (conductivity is reduced).The probe is designed to work with the PZ-828, PZ-828 RC liquid control relays
