Advantages and Disadvantages of Integrated Temperature Transmitter

The integrated temperature transmitter has the following advantages:
(1) It saves the investment of the compensation wire or extension wire of the thermocouple system, and only needs two common wires to supply power and output signals, which has great economic benefits for process control with many side wet points:

(2) The strong 4-20 mA DC signal is transmitted from the central control room and the connecting wires in the field, which has stronger anti-interference ability than the compensation wire or connecting line that transmits weak thermoelectric potential;

(3) Small and compact, only a few tens of millimeters of short cylinder, sealed with silicone rubber or resin in the thermoelectric or thermal resistance casing terminal box. Adapt to the production site environment, dustproof, anti-corrosion, no additional space .

The disadvantage of the integrated temperature transmitter is that each type of transmitter is only suitable for a sensitive component of a certain type and specification, and it is also impossible to adjust the range of the range. The versatility is poor; once damaged, it can only be replaced as a whole.

The basic error of the integrated temperature transmitter is less than ±0.5% of the range, and the ambient temperature effect is about 0.05% per 1 °C. It can be installed in the environment of -25 to 80 °C.
