Integrated Temperature Transmitter is a temperature sensor and signal converter composition, signal converters installed in the cold junction temperature sensor junction box, the temperature sensor affected by temperature resistance or potential effect generated by the conversion produces a differential voltage signal. Integration of temperature change using binary instrumentation is round, small size, can be installed in the junction box thermocouple or RTD, constitute unified meter can also be installed independently in the controller, and thermocouple constitute integration, easy installation without compensation wire, reduce the cost. In a very simple way to convert the temperature signal in the range of -200 ~ + 1600 ℃ for two-wire 4 ~ 20mA DC electrical signal is transmitted to the display device, regulators, etc., to achieve the temperature Accurate measurement and control. Integrated temperature transmitter is a modern industrial site, research institutes temperature measurement and control of replacement products, distribution systems, digital bus system essential products. Integrated thermocouple temperature transmitter has a simple structure, save lead, the output signal, strong anti-interference ability, good linearity, simple display instruments, solid module earthquake proof, have reverse polarity protection and current limit protection, working and reliable. It can be produced in a flameproof. Wire 4 ~ 20mA DC output. Transmission distance, anti-interference ability. Cold end, drift, non-linear automatic compensation. High accuracy, good long-term stability. Temperature inside the module using epoxy resin casting process, adapted to the harsh and dangerous places. Integrated design, simple and reasonable structure, can directly replace ordinary assembly type thermocouple, RTD. Mechanical protection IP65. Thermocouple temperature change can avoid compensating cables, and reduce costs. LCD, LED, and other indicator pointer facilitate timely monitoring site. Site ambient temperature> 70 ℃, the transmitter and field display instrument can be separated (isolated) installation.
