Air flow compensated temperature transmitter and measuring method

Abstract

The invention relates to an air flow measurement unit for an air flow compensated room temperature transmitter (RTS). The air flow measurement unit comprises a known mass, at least one resistive heating element, a thermistor, at least one heat sink, and data transmission means configured to transmit a resistance signal of the thermistor. The at least one resistive heating element is configured to heat the known mass to an elevated temperature and the thermistor is configured to measure temperature of the heated known mass during cooling for calculation of a cooldown time of the known mass defined based on the measured resistances. The invention further relates to an air flow compensated room temperature transmitter, an air flow measuring method for an air flow measurement unit, an air flow compensated ambient temperature measuring method for an air flow compensated room temperature transmitter and a computer program product.
