5000TC Toroidal Conductivity Cells

As Honeywell Field Product channel partners, Fluidic offer a range of conductivity cells and analysers.  For higher conductivity applications, generally in the milliSiemens/cm range,  we offer Honeywell’s rugged range of 5000TC toroidal conductivity cells.


Honeywell 5000TC toroidal conductivity cells are available in 4 material types…

  • PEEK offers the broadest range of applications within the chemical, pulp & paper, and refinery industries.
    The only known materials to severely attack PEEK are very high concentrations of acids, such as nitric or sulfuric. It has a higher temperature capability than the Polypropylene or PVDF sensors.
  • PFA Teflon is used in extremely corrosive applications, especially high concentrations of sodium hydroxide, nitric acid, sulfuric acid, or hydrofluoric acid. It has the highest temperature rating of the four sensor types. It is also ideal for applications which have a tendency to coat the sensor.
  • Polypropylene is a low cost option, particularly common in wastewater applications where the temperatures and pressures are close to ambient and chemical compatibility is not a serious concern.
  • PVDF is one of the most rigid and abrasion-resistant materials. It has good chemical resistance to halogens, such as chlorine or bromine. It is ideal for applications which require higher pressure ratings, but do not have high temperatures, such as water treatment applications in the semiconductor industry.


Additionally, Honeywell 5000TC sensors are available with a number of different mounting types. These include immersion mounting (CPVC or PVDF materials, also PVC junction box), union mounting (316SS, CPVC or PVDF materials with optional 2” tee), sanitary mounting (316 SS 2” tee with heavy-duty clamp), or insertion/removal mounting (316 SS or CPVC material).


Honeywell contacting conductivity cells are manufactured to a high standard with the use of rugged materials. Conductivity measurement ranges for the 5000TC Toroidal cells are typically 0.2 to 2000 milliSiemens/cm and suitable for temperatures up to 120C and flowrates up to 3m/s.  Please check with Fluidic for help with product selection for your application.

All Honeywell conductivity cells have integral temperature compensators that are compatible with Honeywell instrumentation.  Typical applications for Honeywell conductivity instrumentation includes water treatment plants, boilers, cooling towers, CIP systems and acid/base concentration measurements.  Total Dissolved Solids (TDS) can also be determined with the use of Honeywell conductivity cells if the contents of the suspect solution are known.  For lower conductivity measurements (generally microSiemens, µS/cm, ranges) please see our range of Honeywell Contacting conductivity cells.


Fluidic hold an exclusive channel partner agreement with Honeywell Field Products division.  Our instrumentation engineers are product trained and able to help with instrument selection within the full Honeywell Field Product instrumentation portfolio.  This includes accompanying pH, ORP, conductivity or DO instrumentation.  Fluidic order directly with the factory via an exclusive channel partner web portal and hold stock for some common lines.  Please contact either office for more information (Glasgow 0141 641 5920 or Warrington 01925 572401).
