Description
The GF Signet 3-2850-52-41 is a compact, integral conductivity and resistivity sensor designed for precise measurement in water treatment and process applications. Manufactured by Georg Fischer Signet, this sensor features a robust yellow housing with an attached electrode probe, making it suitable for inline installation in piping systems. It measures conductivity in the range of 0.055 to 200 μS/cm and resistivity up to 18.2 MΩ·cm, with integrated temperature compensation for accurate readings. Key benefits include easy integration with Signet transmitters, high chemical resistance due to materials like PVDF and stainless steel, and low maintenance requirements. It's ideal for reverse osmosis (RO) feed monitoring, as indicated by the 'RO FEED COND SENSOR' label on the unit. Advantages over similar products include its digital (S3L) output for noise-free signal transmission and compatibility with multi-parameter controllers. Drawbacks may include limited high-conductivity range compared to specialized models and the need for periodic calibration. Based on attached images, the unit appears used with minor wear, such as tape on the probe and slight discoloration, but no major damage. Serial number visible as 32965324 / 113101 80435. For resources, refer to the official GF Signet 2850 datasheet (available at https://www.gfps.com/content/dam/gfps/us/doc/tech-data-sheets/signet-2850-conductivity-sensor-electronics-en.pdf) and model decoder guide (search 'Signet 2850 model number breakdown' on gfps.com).
