ES-5 Series Toroidal Conductivity Sensors
The AquaMetrix ES-5 series toroidal 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 4-20 mA output.
Each sensor comes standard with a Pt100 RTD temperature device, which provides automatic temperature compensation to 25°C (77°F).
The AquaMetrix ES-5 sensors 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 two-wire wound toroids encapsulated in a potting compound and encased in a plastic body. One toroid acts as a transmitter 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 process solution.
