Know Something About Integrated Temperature Transmitter

First, integrated temperature transmitter can realize functions of managing the range of remote information management, configuration, variable monitoring, calibration and maintenance through HART communication device.

Second, integrated temperature transmitter can be adjusted according to the user's actual needs according to direction of the transducer, and display the measured medium temperature transmitter, the sensor values change, the output current and percentage rate.

Third, integrated temperature transmitter uses silicone rubber and epoxy resin sealing structure, so it has the advantages of resistance to shock , moisture resistance, and is suitable for installation at the scene of the harsh environment.

Forth, installed in the terminal box use of thermocouple, heat resistance, it can directly output 4-20 ma, 0 to 10 ma of the signal, which can not only save the expensive cost of compensation conductor, but also improve the anti-interference ability in the process of signal transmission over a long distance.

Fifth, thermocouple transmitter has cold end temperature automatic compensation function;

Sixth,  integrated temperature transmitter has the advantages such as the high precision, low power consumption, the use of wide temperature range, stability and reliability on working and so on.

Seventh, wide applicable scope. Integrated temperature transmitter can form integrated installation structure with thermocouple, heat resistance, and can also be used as a functional modules installed on the testing equipment and instrument panel.

Four Things About The Integrated Temperature Transmitter

Integrated temperature transmitter has the advantages of smaller volume, but widely use. And here are some things you should pay attention when using it.


First, for the wiring, the safety spark circuit (the input signal line), must be with an insulating sleeve wire or a shield, and non safety spark circuit wiring should be isolated from the safety spark circuit to avoid mixed contact.


Second, wire different types of integrated temperature transmitter according to the specification. And there should be nothing wrong with explosion-proof instrument which has the safety spark circuit. You should carefully check whether there is a short circuit or any other wrong wiring.


Three, in the use of the integrated temperature transmitter, special attention should be paid to the distinction of common type and intrinsic safe type. Ordinary type cannot be installed in hazardous area, while the intrinsic safe type can be done that.

Four, RTD transmitter input is in the three-wire system. Resistance of each connecting wire line should be equal and in the same environment temperature range.
