ES Series Electrodeless Conductivity Sensors

ES-1 Series Toroidal Conductivity Sensors

The AquaMetrix ES series toroidal conductivity sensors are used in processes where conventional contacting sensors may become fouled or corroded.

Each sensor comes standard with a PT1000 RTD temperature device, which provides automatic temperature compensation to 25°C (77°F).

The AquaMetrix ES sensors can be mounted in flow through applications or submersion mounted in tanks or open vessels.
.
Operating Principle:

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.

Notes:

These sensors are made to interface with a third party analyzer. We recommend the Knick Eco Stratos.

Features

ES-5 Series 4-20 Direct Output Toroidal Conductivity Sensor

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.

Operating Principle

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.
(The terms electrodeless and toroidal are interchangeable in regards to this type of conductivity sensor.)
