Industrial Applications

1. Hydronic heating supply/return monitoring

Used in closed-loop water circuits where a protected immersion probe is needed to measure pipe or vessel temperature without exposing the sensing element directly to flow or contamination.

Problem Solved

Provides stable liquid temperature feedback while the protection pocket isolates the sensor from process media and maintenance disturbances.

2. Buffer tank temperature stratification control

Fits buffer tanks and thermal storage vessels where a 100 mm immersion depth is enough to read water layer temperature through a threaded pocket.

Problem Solved

Enables reliable tank temperature control without draining the system for sensor replacement.

3. Hot water plant instrumentation

Suitable for domestic hot water or plant-side water monitoring where moderate protection class and a pocket-mounted sensor are preferred for serviceable temperature measurement.

Problem Solved

Allows maintainable temperature sensing in wet mechanical rooms while keeping the sensing element protected.
