The GF Signet 2850 conductivity/resistivity sensor electronics come in various configurations for flexible installation. Choose from the universal mount version for pipe, wall, or tank mounting or the threaded j-box version for submersible sensor mounting. The sensor has two output options: digital or 4 to 20 mA, and it features NEMA 4X/IP 65 enclosures, allowing long cable runs of up to 1,000 feet. EasyCal is a standard feature for simple field calibration.
Product details
The GF Signet 2850 conductivity/resistivity sensor electronics are designed to provide maximum installation flexibility. They are available in various configurations, including the universal mount version, which can be used for pipe, wall, or tank mounting, enabling single or dual inputs using any standard GF Signet conductivity/resistivity sensor. The threaded j-box version can be used with the same sensors for submersible sensor mounting.
The GF Signet 2850 conductivity/resistivity sensor is also available as a combined integral system configuration for in-line mounting, which includes a conductivity electrode with a choice of 0.01, 0.1, 1.0, or 10.0 cm-1 cell constants. This configuration allows for accurate sensing across a broad dynamic range.
The GF Signet 2850 conductivity/resistivity sensors are available with a choice of two outputs: digital or 4 to 20 mA. The digital (S3L) output version of the GF Signet 2850 conductivity/resistivity sensor enables up to six sensor inputs directly into the Signet 8900 Multi-Parameter Controller, while the two-wire 4 to 20mA output is available with eight 4 to 20 mA output ranges for each electrode cell constant. Each range can be inverted and is field selectable by the user.
The GF Signet 2850 conductivity/resistivity sensor features NEMA 4X/IP 65 enclosures, which allow wiring connections with long cable runs of up to 1,000 feet (305 m). The sensor also includes EasyCal as a standard feature, which automatically recognizes conductivity test solution values for simple field calibration. A calibration tool is available for validation of the sensor electronics according to USP requirements, providing accurate and reliable readings.
