2850 Conductivity-Resistivity Sensor Electronics and Integral System
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 (digital output only) 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 100 MΩ to 10 kΩ. Each range can be inverted and are field selectable.
All 2850 units are available with a choice of two outputs, digital (S3L) or 4 to 20 mA. The digital (S3L) output version allows for up to six sensor inputs directly into the Signet 8900 Multi-Parameter Controller. The two-wire 4 to 20 mA output is available with eight 4 to 20 mA output ranges for each electrode cell constant.
All 2850 units are built with NEMA 4X/IP 65 enclosures which allow wiring connections with long cable runs of up to 305 m (1,000 ft). EasyCal is a standard feature that automatically recognises conductivity test solution values for simple field calibration. A calibration tool is available to validate of the sensor electronics according to USP requirements.
