The system is composed of the NS-PT10 series pressure transmitter and the NS-YB04 single-screen digital display control instrument. It compares the pressure inside the pipeline with atmospheric pressure, with the instrument displaying real-time values and outputting a 0–10 V analog signal. Meanwhile, two configurable relay signals are provided for alarm control. The sensor body is equipped with a potentiometer for zero adjustment, and the instrument panel is furnished with a one-button zero-clear function.
