Instruments & Controls

The Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The universal mount version is for pipe, wall, or tank mounting and enables single or dual inputs using any standard Signet conductivity/resistivity sensor. The threaded j-box version can be used with these same Signet sensors for submersible sensor mounting. 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 18.2 MΩ to 10 kΩ. All 2850 units are available with a digital (S3L) output, or a single 4 to 20 mA. The digital (S3L) output version can be paired with the 9900 or 9950 Transmitter.

Digital (S3L) interface or two-wire  4 to 20 mA output. For use with ALL Signet conductivity electrodes.
