Installation & Best Practices
-
Mount sensor probe where it is exposed to representative air or fluid, avoid extremes or localized hot spots.
-
Ensure the cable routing avoids sharp bends, abrasion, or exposure to chemicals that degrade PVC.
-
Use proper connectors and wiring practices; longer cable runs may add resistance, but reference specs for accuracy.
-
Inspect for corrosion on probe; clean periodically if buildup affects readings.
