SI31012
- Category: Water quality, SENSORS, Conductivity Sensors
The B&C Electronics SI31012 probe is a 4-electrode electrical conductivity probe with a built-in Pt100 temperature sensor, especially suitable for industrial applications where measurement stability and precise compensation against temperature variations are required.
Its 4-electrode design allows it to work in a wide range of conductivities, making it suitable for environments such as industrial processes, wastewater treatment, textile industry, chemical and electroplating.
The process connection is DN 40 using the SZ724 fitting according to DIN 11851-52. This SZ724 consists of a conical collar and a DN40 fixing ring in AISI 304, allowing the SI 31012 probe to be compatible with DN40 female connections of the DIN 11851-52 series.
Its industrial construction, with a PVDF body with PVC extension and AISI 316 stainless steel electrodes, provides good resistance and compatibility for most applications in the sector.
