Integrated temperature transmitter, can convert temperature signal to two wire 4 ~ 20 madc electrical signals, with strong versatility, long transmission distance, strong anti-jamming capability, high measurement precision, long-term stability is good wait for an advantage. At the same time, integrated temperature transmitter, but also can directly replace ordinary prefabricated thermocouple, thermocouple, and the thermocouple, thermocouple integrated installation structure formation, can also be used as a functional modules installed on the testing equipment and instrument panel. Integrate temperature transmitter, based on the measured hydrostatic principle of proportional to the height of the liquid, based on the measured hydrostatic principle of proportional to the height of the liquid, USES the overseas advanced isolation diffusion silicon sensing element or sensitive ceramic capacitance pressure sensor, the static pressure is converted to electrical signals, bulk silicon sensing element or sensitive ceramic capacitance pressure sensor, the static pressure is converted to electrical signals, after temperature compensation and the linear correction, converted into a standard electrical signals. And, integrated temperature transmitter is measured by the hydrostatic pressure from work. It usually chooses silicon pressure measured by pressure sensor will be converted to electrical signals, then through amplifying circuit amplification compensation and compensation circuit, sensor to measure the pressure is converted into electrical signals, then through amplifying circuit amplification compensation and compensation circuit, and then by 4 ~ 20 ma current output. At the same time, integrated temperature transmitter through balancing circuit will this small capacitance change into standard current ( Or voltage) Output, thus gets the change into a linear relationship with the pressure of the output current ( Or voltage) The signal. Output, thus gets the change into a linear relationship with the pressure of the output current ( Or voltage) The signal. Working principle of the inductance of the transformer is also similar.
