Choose the probe type from the medium, pressure and temperature

The four mechanical families do not share the same wetted materials or service limits.

  • Type A uses an ABS body with graphite electrodes and is reviewed to 0.8 MPa. Type B uses nylon fibre with 316 stainless steel; Type C uses nylon fibre with graphite. Types B and C are reviewed to 1.0 MPa.
  • Type D uses 316L and PEEK wetted materials, supports the reviewed high-temperature configuration and is reviewed to 2.0 MPa. Confirm whether the installation uses the Type D two-wire 4-20 mA option or the standard simultaneous-output configuration.
  • Select a documented range. Types A/B/C support 0-2000, 0-5000, 0-10000 or 0-20000 µS/cm; Type C also supports reviewed custom ranges. Type D supports 0-50, 0-500, 0-10000 or 0-20000 µS/cm.
  • Install the conductivity cell where it remains wetted and where bubbles do not collect across the measurement opening. Confirm immersion depth or NPT3/4 process geometry before release.
  • The probe is not maintenance-free: deposits, oil, biofilm and scale change the cell response. Define cleaning access, inspection frequency and the reference solution or comparison method.
  • IP68 applies to the probe. Cable entries, junctions, controllers and enclosures require their own environmental protection.
  • A matching manual documents calculated TDS and salinity data, but the direct measurement is EC. Confirm the ordered firmware/register set, conversion, units, temperature basis and acceptance method before using either derived value.

Typical applications

  • Freshwater, aquaculture and surface-water conductivity trend monitoring
  • Wastewater and process-water monitoring after wetted-material and fouling review
  • Pipe or tank installations using simultaneous analog and Modbus signals
  • Higher-temperature or higher-pressure service using the selected Type D configuration
