Electronics are available in various configurations for maximum installation flexibility. The universal-mount version is for pipe, wall, or tank mounting and uses the CDCE-90 Series conductivity/ resistivity sensor (sold separately). It is also available as a combined integral system configuration for in-line mounting and includes a conductivity electrode in a choice of 0.01, 0.1, 1.0, 10.0 or 20.0 cm–1 cell constants. The CDTX-2850 is ideal for applications with a conductivity range of 0.055 to 400,000 ?S or a resistivity range of 18.2 M? to 10 k?. All CDTX-2850 units are built with NEMA 4X (IP65) enclosures which allow output wiring connections with long cable runs of up to 305 m (1000 feet). The two-wire 4 to 20 mA output has eight 4 to 20 mA output ranges for each electrode cell constant. Each range can be inverted and is field selectable. Standard calibration automatically recognizes conductivity test solution values for simple field calibration. A certification tool is available for validation of the sensor electronics according to USP requirements.

Rated 5 out of 5 by from Start Up Achieved Availability of this instrument helped our customer out of a situation that could have delayed start up. There was a hiccup due to delivery, but all things considered, we were able to assist our customer on a timely basis.

Rated 4 out of 5 by from Sensor Cap This is one of the few conductivity transmitters that I could find with transmitter and probe offered as one unit, AND as a blind configuration (no display.) I have used many of these on various projects, and the configuration jumpers on the transmitter board makes it easy to configure with different cell constants and ranges. The quarter-turn CAP (top cover) seems to fit a little loose... I have two units installed in an area where there is steam and constant light splashing, so I will see in time of the IP65 rating holds up.

Can you confirm that the measurement/output for these sensors are microsiemens/centimeter (&mu;S/cm) and not microsiemens/meter (&mu;S/cm)?

Asked by: Automation Rob
The output range is microSiemens / centimeter (uS/cm). CDCE-90 sensors are sold separately.

Please, could you inform me if the &quot;Update Rate&quot; is the same as the &quot;Response Time&quot; of the sensor?

Asked by: DanPer
Thank you for your inquiry! The update rate will be the same as the response time for the CDTX-2851.
