Cooling Tower Contacting Conductivity Sensors

Contacting conductivity sensors are ideal for use in cooling towers and boilers, reverse osmosis equipment, and other non-oily applications. It measures conductivity of a solution via electrodes. A variety of cell constants are available to handle a range of conductivities. They are available in several different configurations.

These cell constant 1.0 sensors are designed for cooling towers with water up to 30,000 μS/cm. Lower pressure (up to 150 PSI, 10 atm) polypropylene sensors are available with graphite or stainless steel electrodes, and may be installed inline or submersion. High pressure (up to 300 PSI, 20 atm) inline sensors are constructed from stainless steel and PEEK.

WebMaster controllers require active sensors. These sensors contain electronics to convert the sensor signal to a voltage that these controllers can read. W400 series controllers use passive sensors that have cables dressed specifically for them. W100 series controller’s passive sensors are dressed differently.

Performance specifications vary with the type of controller, refer to the controller brochure. Typical cooling tower temperatures are 0 to 70 °C, 32 to 158 °F.
