Tensosensitivity of the Hot-Wire Probe

Abstract

The contribution due to false electric signals may depend on the probe-overheating factor and on the manner in which the electric power is supplied to the probe i.e., on the anemometer type. In a constant current anemometer, it is possible to measure and separate out the noise moving to the electric circuit of the anemometer, it is not the case with hot-wire anemometers of other types. To separate out the strain-induced component from the total signal is a very difficult task since this component arises alongside with the useful signal and directly at the hot wire. Therefore, in order to develop a way for diminishing the detrimental component moving to the strain gage effect or have a possibility to apply a proper connection for it, it is necessary to analyze the influence of different flow quantities, hot-wire probe properties and specific features of different types of hot-wire anemometers on probe tensosensitivity.
