Introduction: rail temperature transmitter adopts two-line transfer mode ( two wires as a power input, output signal with the common transmission line ). The thermocouple, thermal resistance signal into the input signal or the measured temperature or linear4 ～20mA output signal, the transmitter can be installed on the thermocouple, thermal resistance of the wiring box to form an integrated structure with the. It is a new generation of measuring instrument can be widely used in metallurgical, petrochemical, power, light industry, textile, food, national defense and scientific research and other industrial sectors.

Characteristics of temperature transmitter

1, using epoxy resin sealing structure, so the seismic, heat resistance, suitable in harsh field environment in the installation.

In2, field installation of thermal resistance, thermocouple junction box, direct output from 4 to 20mA, this will not only eliminate expensive wire compensation costs, but also improves the signal long distance transmission of anti jamming capability.

In 3, high precision, low power consumption, using a wide range of ambient temperature, stable and reliable work.

4, adjustable working range, and has a positive linear functional, thermocouple temperature transmitter has a cold end automatic compensation function. A wide range of applications, both with a thermocouple, thermal resistance formed integration site installation structure, but also can be used as a function module is installed into the testing device.

Output:2, in the range of4 ～20mA DC signal output with the thermal resistance thermometer output resistance signal into a linear, with the thermal resistance thermometer input temperature signal into a linear; with the thermocouple input the millivolt signal into a linear, also with a thermocouple thermometer input temperature signal into a linear.

3, the basic error:± 0.2%,± 0.5%

4, transfer mode: two-wire system

5, transmitter power supply voltage12V minimum, maximum 35V, rated voltage24V.

6: limit, load two negative load resistance calculated by the following equation
