On-site example:
A certain automation equipment company in Shanghai used a 360-line thermocouple converter to monitor the temperature rise of windings in 72 inverter motors in the industrial field of a refrigeration industry in the United States. After mutual efforts, they have successfully put into operation and passed acceptance.
In the course of the project, we faced two thorny problems: electromagnetic interference and heavy load. Our researchers used a series of advanced technological means and worked hard to overcome the difficulties that they faced. This will be used in the electromagnetic environment in the future. A successful example is the comparative application of the first-line bus technology on the harsh field. In the process of solving technical problems, the technical staff of this institute had a deeper understanding of the devices of DALLAS Corporation in the United States, explored many valuable experiences in the application of first-line bus technologies, and received strong support from DALLAS.

High temperature experiment:
Put only one set of thermocouple converter 60 into the heating box, control the ambient temperature of the converter to 55°C, and maintain continuous operation for 8 hours, and compare the temperature parameter read by the DZM-64 first-line parameter inspection instrument with the mercury thermometer. The test results all meet the specifications of the nominal 50°C condition, that is, the thermocouple converter can relax the working condition by 5°C. September 15, 2003
On-site example:
A power plant in Heilongjiang Province installed a 353-channel thermocouple converter to measure the temperature of the boiler wall and the temperature of the pipeline. The environment was relatively poor. Because the application of the one-line bus technology greatly reduced the work of wiring check lines, the measuring point line in the system was very clear. To bring a lot of convenience to users, and the work is stable and reliable, after nearly a year of continuous operation, the effect is significantly better than the traditional test methods, is now ready to continue in another boiler temperature measurement project.
