Electrodeless Conductivity Sensors

Electrodeless conductivity sensors measure conductivity of a solution utilizing encapsulated, non-contacting, toroidal technology.

They may be installed in a variety of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm. The non-contacting, toroidal sensor technology is immune to thin coatings and the contamination and calibration problems that direct contacting sensors are prone to.

• CPVC or PEEK construction
• In-line or submersion

W400 and WebMaster controllers require active sensors. These sensors contain electronics to convert the sensor signal to a voltage that these controller can read. Each sensor is specific for the range of conductivity that it can detect.

Measurement Performance for Active Sensors:

W100 controllers require passive sensors. A single sensor functions over the entire range of conductivity
(500 - 2,000,000 µS/cm), and the range is selected in the controller's software.
