Model CS40 Conductivity Sensor
Click on part number above to request an RFQ or place an order online.
  • Measures conductivity directly in process temperatures up to 150°C
  • O-ring seals used on all versions for high on-stream reliability
  • Optional wet-tap valve allows insertion and removal while line is under pressure
The SDI Model CS40 sensor has been designed for a broad measurement range in difficult process conditions. It can be installed I in submersion, insertion, or wet-tap configurations, and is good for most applications from high purity water to high chemical concentrations.

Application Notes
Wetted materials of construction are 316 stainless steel and Kel-F or Teflon, depending on the range of temperature required. All possible leak paths through the sensor are double sealed with EPR O-rings for maximum on-stream reliability. The front O-rings protect the back ones from chemical attack, giving more than double the service life than can be expected from single sealed units.

Process connections are made via a bored through swage fitting with 3/4" NPT threads. This fitting can be screwed into a line, a tank, or the optional wet-tap valve assembly. It can also be turned around and connected to a standpipe for use in a submersion configuration. Available probbe constants range from 0.01 to 20.0 giving it the broadest range of application of any of our sensor models.
