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.

Current Output
Field-Selectable Ranges
    Factory Set Span 4 to 20 mA:
    0.01 Cell: = 0 to 100 µS (Integral mount only)
    0.10 Cell: = 0 to 1000 µS
    1.0 Cell: = 0 to 10,000 µS
    10.0 Cell: = 0 to 200,000 µS
    20.0 Cell: (CDCE-90-20B, not for integral mount) = 0 to 400,000 µS
Maximum Loop Resistance: 50? at 12 Vdc, 325O at 18 Vdc, 600O at 24 Vdc
