GF Signet 3-2850-52-39 2850 Conductivity Electrode, K=0.01, 4-20 mA Output, 3/4"NPT
Product Description
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 400 feet.
The 8900 Multi-parameter controller allows for up to six 2850 (S3L) output conductivity sensors to be used with the Signet 8900 Multi-parameter controller. The two-wire 4 to 20 mA output version is available with eight 4 to 20 mA output ranges for each electrode cell constant. Each range can be inverted and is field selectable.
EasyCal is a standard feature that automatically recognizes conductivity test solution values for simple field calibration. A certification toll is available for validation of the sensor electronics according to USP requirements.
Product Information
Description
• Signet 2850 Conductivity/Resistivity Sensor Electronics provides either a two-wire 4 to 20 mA output or Digital (S3L)format.
• The 4 to 20 mA output models provide eight ranges for each electrode cell constant, plus the ability to invert each range.
• The EasyCal feature allows the devices to automatically recognize standard conductivity test solution values for simple fi eld calibration.
• The Conductivity Sensor provided with integral systems will have its custom cell constant information programmed into the electronics at the factory to provide a 2% sensor accuracy. See page 6 for details.
