Changbin chemical plant: one sensor on the same tank since 2011
Thermal monitoring of oil-spray sealed tanks, where ordinary adhesives and drilled probes fail.
- 15 yrsSame unit since 2011

- Oil mistChemical exposure survived
The problem
At a chemical plant in Changbin industrial park, oil-sealed reaction vessels constantly throw a fine mist of hot oil into the air. Conventional thermometers fall off the tank wall within three months — the oil dissolves the adhesive. And you can't drill a probe into a vessel that's running.
What was installed
A Thermalpas M-TYPE sensor was bonded to the tank wall with a patented adhesive certified to ASTM D-3654 for oil and chemical resistance. The cable is rated to 180°C, the housing is IP68, and the adhesive does not degrade in oil mist. Tank temperature stability was tracked to estimate when the oil seal would need replacement.
The outcome
The same Thermalpas unit has monitored the same oil-sealed tank since 2011 — fifteen years without replacement. It is the longest adhesive-durability record under chemical exposure in the Thermalpas field history.
