Method for determining the transmitted band of thermo-anemometer and system for determining the transmitted band of thermo-anemometer

摘要

Method of determining the thermonemometer transfer band consisting of the thermonemometer sensor (1) and the associated electronic thermonemometer system (2),where the test periodic voltage signal is brought to the thermonemeter, the frequency of the test signal is changed to the extent examined, and the relative amplitude of the variable output signal from the thermonemometric system is measured for each frequency specified, and the mapping of the measured amplitude to the frequency of the test signal shows the thermonemeter transmission band, is that the periodic electric test signal with the regulated frequency results in an induction tube (6) located near the sensor (1) of the thermonemeter,and from the induction tube (6) through the transformer induction coupling the test signal leads to the thermonemometer sensor (1). The object of the invention is also a system for determining the thermonemeter transmission band.
