Description

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 μS or a resistivity range of 18.2 MΩ to 10 kΩ. 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.
