Isolating explosion type integrated temperature transmitter (hereinafter referred to as the temperature transmitter) is composed of a temperature sensor and a signal converter, a signal converter installed in the cold end connecting box of temperature sensor, the temperature sensor to detect the voltage, resistance signal is directly converted into a 4 ~ 20mA current output. Simple structure, installation, use, maintenance is convenient, is a new generation of temperature detection, control instruments, by the vast number of designers and users of welcome. Has been widely used in petroleum, chemical, metallurgy, power plants, light industry and other departments, with the regulator, recording instruments, computers and other ancillary use, the composition of a variety of measurement control system.
The temperature transmitter according to the temperature sensor, thermocouple and thermal resistance of two series. In each series, according to use the occasion of the different points for flameproof type and ordinary type, according to different output function, divided into field display and not with on-site display. The user can choose the appropriate specifications and models according to the requirements of the use occasions and the supporting instruments.
Explosion proof temperature transmitter is qualified by the national instrument and meter explosion proof safety supervision and inspection station, which can be used in explosive gas environment.
main features
1 wire transmission. The two wires which are supplied by the signal converter are simultaneously transmitted to the output signal.
2 output constant current signal (4 ~ 20mA). Strong anti-interference ability, good transmission performance.
3 signal converter with epoxy resin encapsulated module, with anti vibration, corrosion resistance, moisture and other advantages, can be used for poor conditions.
4. Thermocouple MV signal through the signal converter is directly converted into 4 ~ 20mA current output, with the common cable transmission signal, eliminating the need for expensive compensating lead wires.
5 temperature transmitter with the field shows that the output of 4 ~ 20mA of the current signal, but also in the temperature field to read the measured temperature, to bring great convenience to the operator.
