Conductivity Sensors/Transmitters
The company offers the Type 8225/8220 family of Conductivity Sensors/Transmitters available in local, remote, and extended remote versions.
The company offers the Type 8225/8220 family of Conductivity Sensors/Transmitters available in local, remote, and extended remote versions. Measuring applications include waste water treatment engineering, water treatment and process technology, cooling water monitoring, chemical dosing, and electroplating.

The conductivity transmitters offer an 8-digit, multi-language, digital display featuring automatic temperature compensation, self-diagnosis, filter selection, and a Test Menu for simulating dry run process conditions. They operate on 12-30 VDC, and provide a three-wire 4-20 mA analog output signal. Two optional adjustable 3A relays are available. Transmitters operate in ambient temperatures from 32°F to 140°F, and pressure to 87 PSI. Four sensor probes are offered with sensitivities suitable for media from ultra pure water to concentrated solutions; cell constraints 0.01 and 0.1 are fitted with stainless steel electrodes, and those with cell constants 1.0 and 10 are fitted with graphite electrodes.

The sensor/transmitters are available in local or remote mounting configurations. The local version integrates the conductivity-sensor and a 4-20 mA transmitter with an easy to use digital display/interface in a splash-proof plastic IP65 (Nema 4) enclosure. Remote versions include a separate conductivity sensor and transmitter with digital display.

Remote transmitters are available in panel-mounted or wall-mounted plastic IP65 enclosure versions. Two remote mounting sensor types are available; selection is based on distance of sensor from transmitter. The short distance sensor mounts up to 15 feet from transmitter, the long distance sensor includes a Digital Signal Processor for mounting distances up to 1500 feet from transmitter.

Sensors mount into the process via a specially designed pipe "T" connection. These connections are available in True Union (PVC, PP, PVDF) from ¾ in. to 2½ in. line sizes or Solvent Spigot (PVC, PP, PVDF) slip joints in 1½ in. to 2½ in. line sizes. Stainless steel and Brass pipe "T" connections are available in Weld Ends, Threaded Port (male or female), Flange, or Tri-Clamp fittings in ¾ in. to 2½ in. line sizes.
