    Resistivity or Conductivity Electronics Overview

    The GF Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The threaded j-box version can be used with these same GF Signet sensors for submersible sensor mounting.  Universal mount version used for pipe, wall, or tank mounting and enables single or dual (digital output only) inputs using any standard GF Signet conductivity / resistivity sensor. 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 2850 is ideal for applications with a conductivity range of 0.055 to 400,000 µS or a resistivity range of 100 MΩ to 10 kΩ. Each range can be inverted and are field selectable.

    All 2850 units are available with a choice of a single or dual digital (S3L) outputs, or a single 4 to 20 mA. The single digital (S3L) output version can be paired with the 9900 Transmitter to extend the distance between the measuring points to 120 m (400 ft).

    The 8900 Multi-Parameter Controller allows for up to six sensor inputs directly into the Georg Fischer  Signet  8900 Multi-Parameter Controller. All 2850 units are built with NEMA 4X/IP65 enclosures which allow output wiring connections with long cable runs of up to 305 m (1,000 ft).
