Product description:
I. overview
Flameproof integrated temperature transmitter (hereinafter referred to as the temperature transmitter) is composed of a temperature sensor and a signal converter signal converter is installed in the terminal box cold end temperature sensor, voltage, resistance temperature sensor signal detected directly into 4 ~ 20mA current output. The utility model has the advantages of simple structure, convenient installation, use and maintenance, and is a new generation of temperature detection and control instrument, which is welcomed by the designers and users. At present, it has been widely used in petroleum, chemical, metallurgy, power plant, light industry and other departments, with the regulator, recording instruments, computers and other supporting the use of a variety of measurement and control system.
The temperature transmitter according to temperature sensor, thermocouple and thermal resistance are divided into two series, each series, according to different occasions for flameproof type and common type, output according to different functions, divided into field display and without field display. The user can select the appropriate specifications and models according to the requirements of the use of the situation and supporting instruments.
The flameproof temperature transmitter is tested by the national explosion-proof safety supervision and inspection station, and can be used in explosive gas environment.
Two, the main features
1 two-wire transmission. The two wires supplied by the signal converter also transmit the output signal.
2 output constant current signal (4 ~ 20mA). Strong anti-interference ability, good transmission performance.
The 3 signal converter is encapsulated with epoxy resin, which has the advantages of shock resistance, corrosion resistance, moisture resistance, etc..
4 thermocouple MV signal through the signal converter is directly converted into 4 ~ 20mA current output, with ordinary cable can transmit signals, eliminating the need for expensive compensation wire.
5 with the temperature sensor shown on the scene is not only output 4 ~ 20mA of the current signal, but also in the temperature field to read the measured temperature, to bring great convenience to the operator.
