A digital pressure gauge is an online measuring instrument designed with digital technology architecture and intelligent functions, used to measure and indicate pressure [1-2]. It is widely used in various fields such as mechanical engineering, municipal fire protection, petrochemicals, water conservancy engineering, automotive industry, medical equipment, and research laboratories [6-7] [11].
The digital pressure gauge adopts elastic sensitive components and piezoresistive or capacitive sensing technology, and signal processing is achieved through high-precision ADC and microprocessor. It has the characteristics of high precision, high stability, anti vibration, wide temperature range operation, and high protection level. Adopting digital LCD display, built-in battery power supply, supporting RS485, Modbus and other output interfaces, can be connected to industrial control systems, and has functions such as data recording and intelligent alarm
