SIKA Industrial Thermometers in Heating Systems
The heating technology used in office buildings, shopping centers, residential buildings, and hotels is generally designed in such a way that one or more large-scale heating systems (fossil fuels, but also district heating) are installed centrally in the building.
Several heating strands start at the heating system (flow) and/or several heating strands arrive at it (return). The better a house is insulated, the lower the possible flow temperature.
Various examples of flow temperatures:
- Well insulated building – radiators or convector heaters below 50°C (122°F)
- Poorer thermal insulation – 60 to 65°C (140 to 149°F)
- Area heating (floor / wall) – below 35°C (95°F)
- Low energy house – just above the maximum room temperature (approx. 23°C) (73.4°F)
In practice, the differentiation between the flow and return is different, but on average it amounts to approximately 10°C (50°F) for area heating and approximately 15-20°C (59-68°F) for individual heaters.
With these systems, local measuring instruments only serve as an indicator during the regular inspection of the system to check whether the system is operating correctly, e.g. comparisons of the flow/return temperature. Modern monitoring technology remains unable to replace the regular inspection of the systems.
The measuring points for the temperature (and also pressure) are located at several points:
- In the central heating room.
- In the supply lines to the individual areas of the building.
- In the water distribution in the building, primarily in the flow and return of the system.
- In larger heating systems, industrial thermometers are usually installed to monitor the individual strands. In smaller heating systems, bimetal thermometers are mainly used.
Industrial thermometers type 174HBZ/175WBZ or type 291HBZ/292WBZ are eminently suitable for the temperature measurement.
SIKA industrial thermometers are characterized by their constant measuring accuracy with a long service life. A readjustment is neither necessary nor possible. This minimizes the maintenance workload and prevents the manipulation of the measured value.
Benefits of SIKA industrial thermometers:
- SIKA industrial thermometers do not require any auxiliary energy.
- SIKA industrial thermometers are very easy to read, always indicate the exact measured value, and have a very long service life. Inaccuracies due to aging, such as those that may occur on conventional bimetal thermometers, are excluded.
