SI311 CONDUCTIVITY SENSOR

4 electrodes, K=1cm-1 (2 to 2,000mS) 1″ BSP thread, PVC body material, PT-100 for temperature measurement, up to 80ºC

Manufacturer: B&C Electronics
Category: Water quality, SENSORS, Conductivity Sensors

The B&C Electronics SI311 electrical conductivity sensor is a conductivity cell designed to measure electrical conductivity in a wide variety of industrial processes. This sensor is ideal for measurements above 20 mS/cm and is the preferred choice when a specialized conductivity meter is required.

The SI311 employs a 4-electrode measurement method that automatically compensates for errors caused by dirt on the electrodes. This design reduces electrical contact with the sample and, when the electrodes become dirty, the instrument automatically supplies a higher voltage to maintain a constant field. This ensures high linearity in measurement over time and minimises required maintenance. In addition, thanks to temperature compensation with a PT-100 probe, the accuracy in electrical conductivity measurement is excellent.
