What causes excessively high or drifting conductivity readings on a conductivity sensor?

Excessively high or drifting conductivity values can be caused by:

  • Contamination or residue accumulation inside the media passage hole.
  • Presence of air bubbles or fluid turbulence (ensure full sensor immersion and alignment with flow).
  • Alteration of the sensor tip geometry due to fluid abrasion.
  • Incorrect installation factor setting if installed closer than 20 mm to a metallic wall.
  • Incorrect temperature compensation settings or compromised sealing on the M12 connector.

How to safely clean a conductivity sensor?

To clean the sensor safely:

  • Perform CIP/SIP (Clean-In-Place / Sterilization-In-Place) procedures using detergents compatible with housing materials (e.g., PEEK, stainless steel) and seals.
  • Never use abrasive products, harsh solvents, or sharp objects to scrape off residue.
  • To clean the display screen, apply a mild detergent to a soft cloth and wipe from the center towards the edges.

What causes high conductivity readings or sensor discoloration, and how can the device be cleaned safely?

High readings or red discoloration (rust/pigments) are typically caused by sensor fouling, air bubbles, or changes in probe geometry due to abrasion. For safe cleaning, use standard industrial NEP/SIP procedures with detergents compatible with the housing and sensor tip. Avoid abrasive products, solvents, sharp objects, or spraying liquids directly onto the screen; use a soft cloth instead.

How to safely clean a conductivity sensor probe?

To clean the conductivity sensor probe:

  1. Perform standard CIP/SIP (Clean-In-Place / Sterilization-In-Place) procedures appropriate for your setup.
  2. Ensure the detergent used is compatible with the sensor housing and tip materials (such as PEEK and stainless steel) and does not attack seals.
  3. Do not use abrasive products, solvents, aggressive chemicals, or sharp tools to scrape deposits.
  4. To clean the display screen, wipe gently with a soft cloth without spraying cleaning solution directly onto the screen.
