In the classification of level transmitters, there is a transmitter for deep well level or groundwater level measurement, which has a measuring range of up to 400 meters. The deep-well type level transmitter also has the characteristics of strong anti-interference ability, small temperature drift and high stability. The working environment of the deep-well liquid level transmitter often occurs in the field, the working conditions are relatively harsh, and the cable to be applied in the deep well measurement is much longer than the conventional use, so the length of a single cable will be insufficient, and multiple cables need to be connected for use, but if the cable is directly docked, the electrical performance of the cable docking is poor, and it is easy to form a safety hazard. Under such working conditions, the waterproof junction box is mostly used to transfer the cable connected to the transmitter body and the cable connected to the sensor. In the wiring structure of the deep-well type liquid level transmitter, the power terminal post and the transmitter terminal post are divided on the circuit board of the junction box, so as to separate the connection of the power core wire and the data core wire, the junction box has waterproof and breathable performance, and the lightning protection circuit can be set to prevent lightning strikes, thereby improving the electrical performance of the cable connection and ensuring the safe use of the deep well type level transmitter. This wiring structure greatly protects the safety and practicality of the transmitter in the field. The research and development of this wiring method is based on the specific situation of field use, and solves a big problem for field use. The wiring structure of the deep-well type level transmitter, as a patented achievement of the star instrument, greatly solves the difficult problems of the staff.
