How temperature transmitters convert output signals

The integrated temperature transmitter is widely used in petroleum, chemical, chemical fiber, textile, rubber, building materials, electric power, metallurgy, medicine, food and other industrial fields. The temperature transmitter directly imports the UK imported temperature transmitter circuit and manufacturing process. And structure, maintain the same performance index and appearance as the original imported temperature transmitter; with reverse polarity protection circuit of power supply; linear output two-wire system 4-20mA standard current signal; all products adopt high quality components, reliable performance; thermoelectricity Even temperature transmitters have automatic compensation with cold junctions.

Anhui Tiankang instrument experts described the temperature transmitter module as a 24V power supply and two-wire integrated transmitter. Temperature transmitter products use imported integrated circuits to amplify the signal of the thermal resistance or thermocouple and convert it into an output current of 4-20mA or 0-10mA or an output voltage of 0-5V. Jiangsu Zhongneng Instrument Technology Co., Ltd. can directly measure the temperature of gas or liquid. It is especially suitable for measuring low temperature range, overcoming the influence of condensate on temperature measurement. Temperature transmitter is often used for thermocouple or Thermistor signals need to be transmitted over long distances, when there are strong interference sources in the field, or when signals need to be intervened in the DCS system. The most common temperature transmitters usually have a housing-mounted transmitter (installed in a variety of structural forms of thermocouple and thermal resistance junction boxes that constitute an integrated thermocouple temperature transmitter or integrated thermal resistance temperature transmitter) And temperature transmitters of module structure (independent installation and instrument cabinets, easy to centrally install.
