AquaMetrix Model ES-5 Series Conductivity Sensors

The AquaMetrix Model ES-5 Series Conductivity Sensors are used in processes where conventional contacting sensors may become fouled or corroded. These probes are unique in the marketplace. They are loop-powered and provide direct 4-20mA output. Each sensor comes standard with a Pt100 RTD temperature device, which provides automatic temperature compensation to 77°F (25°C).

The ES-5 Series are equipped with 1.5" MNPT threads on both ends so that they can be mounted for in-flow applications or submersion mounted in tanks or open vessels.

Toroidal conductivity sensors are made up of two0wire wound toroids encapsulated in a potting compound and encased in a plastic body. One toroid acts as a transmitters and the other as a receiver. An electric current is induced between the toroids through the process solution. This current is directly proportional to the conductivity of the solution.
