How to select model code of temperature transmitter ?
Firstly : The temperature transmitter must first select the output signal. The temperature transmitter output signal usually
has two kinds of current and voltage. The current signal is 4-20mA, and the voltage signal has 0-2.5V, 0-5V, 0-10V, etc.
It should be selected according to the requirements of the superior instrument. After the signal is selected, the range is determined. Because the range of the temperature transmitter corresponds to the output signal, it should be selected as appropriate.
Secondly :Temperature transmitters also have a variety of accuracy, ≤ ± 0.2% for general use, 0.1 ° C & ± 0.05% or higher
for high precision, and the accuracy can be selected to meet the requirements.
Thirdly :The temperature transmitter can also select the on-site display function, and can also output signals at the same time. Special environment can also choose intelligent temperature transmitter with HARRT protocol, debugging is convenient
Fourthly :The temperature transmitter has integrated temperature transmitter and split temperature transmitter, which can be selected according to the installation environment. The integrated temperature transmitter has in-line type, rail type and other installation methods, and the in-line type can be installed in the pipeline. For any space, it is fixed by thread and flange. The rail type is suitable for installation in the cabinet cabinet and fixed by rails. The split type means that the temperature sensor and the transmission module are separated, and the temperature of the installation site is too high or the installation space is limited. Generally, the split type temperature transmitter is selected.
Lastly :The temperature transmitter is also available in a variety of materials, such as stainless steel, which can be selected according to the installation environment. Dimensions and sizes vary widely, and the temperature probes for sludge composting may be more than ten meters high, while the high-precision miniature temperature transmitters are only as large as M10 threads.
