This is Direct OEM replacement "Conductivity Probe Sensor" for our Sump Alarm Wi-Fi units. Designed to work by using 3.3V DC circuits this sensor cannot be used by itself without additional PCB board.
It can be used to convert your Float Switch equipped Wi-Fi Sump Alarm unit into Sump Alarm Conductivity Wi-Fi unit. The sensor is intended for clear water applications without debris or sewage.
Do NOT purchase this Sensor if your idea is to use it with NON Wi-Fi unit.
This conductivity sensor is built indoor or outdoor use. Two high grade steel probes mounted to a grounded twisted shielded pair with drain wire for signal insulation and use in close vicinity to pump control conductors.
Sensor is rated for low voltage DC use and conducts in the MilliAmp range when the probes touch clear water. The sensor is an open circuit when wet an performs as a 10K Ohm Resistor when in contact with water. The black conductor is the Anode, and white is the cathode.
The unit ships with 4 Flexible C-Clamps for mounting to 1" to 3.5" pipe, and (4) 10" Wire ties. There are no additional instructions in the shipment.
