What are the characteristics of integrated temperature transmitter _ instrument
Integration of chongqing instrument 17 years production integrated temperature transmitter, temperature transmitter using two wire transfer (
Is a pair of public power and signal output wire)
, the output of measured temperature linearly with 4 ~ 20 ma current signal, can be measured in the process of industrial production - within the range of 200 ~ 1800 ℃ temperature of the medium.
Transmitter can be installed on thermocouple, thermocouple terminal box and the formation of integration of the structure, also make conversion unit can be mounted on the dashboard alone, but with digital display meter, recording meter, controller, PLC and DCS system, temperature measurement control system, widely used in petroleum, chemical, electric power, metallurgy, aviation, shipbuilding, light industry, environmental protection and other industrial and scientific research.
Due to the integrated temperature transmitter is instrument installation, on-site environmental conditions, especially temperature measured medium often reach hundreds or even thousands of degrees Celsius, because of the heat conduction and thermal radiation, the temperature is very high, so the temperature transmitter often work in room temperature is much higher in the bad environment, and stable and reliable performance.
1, two wire transfer.
Two signal converter power supply wire and the output signal.
2, constant current output signal,
Strong anti-jamming capability, remote transmission performance is good.
3, signal converter with epoxy resin encapsulation into modules, has the advantages of shock resistance, corrosion resistance, moisture proof, can be used in conditions of poor areas.
4, the millivolt signal of thermocouple signal converter directly into 4 ~ 20 ma current output, using ordinary cable transmission signal, can save expensive compensation conductor.
5, with the scene shows the temperature of the transmitter output 4 ~ 20 ma current signal, and can read the measured temperature at the scene of the temperature measurement, was a great convenience to the operating personnel.
