How fast will TRIX-8 react to a change in temperature?
The most common industry standard expression for temperature reading stabilisation time is the ‘T90’. This is defined as the typical time taken of a given sensor in a given environment (e.g. moving air, still air, liquid etc) to register 90% of an immediate step change in temperature. The T90 of TRIX-8 is typically less than 5 minutes in moving air of 1m/s. As the thermal step response is basically dependent on the latent heat of the two thermal masses involved (the LogTag and the surrounding environment) and the rate of thermal transfer between them, the T90 is the same irrespective of the difference of temperatures though at extremes (water freezing and boiling points for example) the environment does not behave homogeneously thereby changing the rates of thermal conduction and therefore changing the resulting T90 value. For example: in a situation of a 25°C step change say starting at 10°C and moving to 35°C in moving air of 1m/s, the TRIX-8 will typically register 90% of the step a
