Dual thermocouple structure？Are there two pairs of thermocouple wires in a protective tube? Still like multiple thermocouples with multiple protection tubes. Do it like multiple thermocouples having multiple signal outputs? 1.The dual thermocouple is a device in which two pairs of electrodes are installed in a protective tube to measure the temperature at the same measurement point, and then the measurement data is transmitted to the temperature control system and display and recording equipment.When the computer was not developed before, Meet the requirements of multiple devices enjoying the same data. 2.Multiple thermocouples are generally used in chemical synthesis towers or oil refining equipment.It measures the temperature of various regions between a measurement point that extends longitudinally by several tens of meters.Using a common negative electrode, a maximum of 6 positive electrodes can be used. Weld a positive electrode on the negative electrode every interval. In some high-pressure pipelines, the process requires as few openings as possible. We used a double-branch thermocouple. There are two measuring elements in a bushing, and then two independent signals are sent to the DCS and ESD systems. However, this situation is quite special. In general, we still use two single branches to send signals to the two systems respectively. Multi-branches also come in contact, such as the catalyst layer temperature detection in the synthesis tower. The synthesis tower supplier will provide two cylindrical thermocouple beams with the tower. Each beam has multiple detection elements. The transmitter sends the temperature signal of each point to the DCS.
