The signal line and the power line must be separated. When using the analog signal for remote control of the inverter, in order to reduce the interference of the analog quantity from the inverter and other equipment, please control the signal line and the strong circuit of the inverter (main circuit). And the sequence loop) separate the lines. The distance should be more than 30cm. Even in the control cabinet, it is necessary to maintain such wiring specifications. The control loop between this signal and the frequency converter must not exceed 50m. The signal line and the power line must be placed inside different metal pipes or metal hoses separately: if the signal line connecting the plc and the inverter is not placed in the metal pipe, it is highly susceptible to interference from the inverter and external equipment; There is no built-in reactor, so the input and output stage power lines of the inverter will have strong interference to the outside. Therefore, the metal tube or metal hose for placing the signal line should be extended to the control terminal of the inverter to ensure the signal line. Completely separated from the power line.
Compact Temperature Sensor We have many products in marine temperature sensors, and our small marine temperature sensors have been traveling in various oceans. Our sensors are not only used in ship mechanical equipment, but also used in freight yards. Our small marine temperature sensor can be used to monitor the marine mechanical equipment and the temperature and humidity in the warehouse. Moreover, our sensor has been used in the oil separator module for a long time, and its performance is very stable.
