Typically not. Heat tracing is primarily used for temperature maintenance. Heat-ups in short periods of time (minutes to a few hours) will most likely require more heat than that needed to maintain the temperature at the desired temperature above ambient.


This is a common term as it relates to thermodynamics and heat transfer calculations.
It is a state of thermal dynamics where the stabilized temperature is a result of the heat input equal to the heat loss.


For accurate SO2 measurement a testo fluegas analyser must always be equipped with a SO2 and NO2 cell. NO2 has a negative impact on the SO2 reading by 110%. If the analyser measures NO2, it will automatically compensate for this. If not, then the SO2 reading might be far out depending on NO2 in the flue gas.

Installing the cable on top or directly at the bottom of a pipe is not recommended as it could result in mechanical damage to the cable.

On top of the pipe the cable is susceptible to personnel walking on cable.

When installed on the bottom of the pipe, damage may be caused by placing the pipe with the cable in a pipe rack. The ideal location is at 5 or 7 o’clock. Locating the cable at 2 or 10 o’clock is acceptable. Installation ease should dictate the selection of these...


Yes. However, the method of temperature control must address the fact that the heat loss will be different for the two ambient conditions.

For line-sensing control the sensor should be located on the outside portion of the pipe.

With ambient sensing the sensor will be outside as well. In both cases, temperatures of the inside/indoors pipe section should be determined to make sure that product, pipe, or cable maximum temperature ratings are not exceeded.

  • Provides protection of personnel against hot surfaces
  • Minimizes heat loss and allows the pipe temperature to increase above ambient temperature based on the amount of heat added by the heat tracer
  • Conserves Energy

Yes. The heat losses without thermal insulation are excessive and not practical to compensate for with heat tracing.


Focus is the most critical element in recording a thermal image. Focus and the perspective of the target area are the image characteristics that cannot be changed.


Yes.  Thermal imagers operate in a range of the spectrum outside the visible light wavelengths and is unaffected by light (except as it is a source of heat).
