ABSTRACT:
The platinum resistive sensor of a temperature measuring surface probe has a resistance greater than the resistance to which the associated meter is calibrated. This provides a compensation that is a function of temperature and decreases errors due to heat loss from the probe. An immersion probe having no heat loss can be used interchangeably with the same meter by adding sufficient fixed resistances in the circuits of the two probes to provide equal resistance outputs to the meter from both the probe that experiences no loss and the one that does, with the meter being calibrated to a standard resistance curve.
