Abstract

The invention relates to the technical field of pressure gauges, in particular to a micro-power-consumption digital display pressure gauge which comprises a single-chip microcomputer connected with a power source through a circuit. The pressure sensor is a diffused silicon oil filled body sensor, and the pressure sensor is electrically connected with the single chip microcomputer through an A/D converter; and the display is electrically connected with the single chip microcomputer through a circuit. The total power consumption of the pressure sensor, the display, the A/D converter and the single chip microcomputer of the micro-power-consumption digital display pressure gauge is low, longer power supply can be achieved through the two batteries with the capacity of 8500 mAH, and the theoretical service life exceeds 10 years.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a digital display pressure gauge with low power consumption. Background technique [0002] Pressure gauges are widely used in petroleum, chemical, electric power and other fields. Pressure gauges can be divided into mechanical pressure gauges and electronic pressure gauges. The traditional mechanical pressure gauge shows the pressure through the elastic deformation of the sensitive element in the watch, and then the conversion mechanism of the watch movement transmits the pressure deformation to the pointer to cause the pointer to rotate. [0003] The digital pressure gauge is an online measuring instrument controlled by a single-chip microcomputer. It uses long-term battery power supply mode, no external power supply, easy to install and use. The digital pressure gauge fundamentally overcomes many shortcomings of the pointer pressure gauge, such as low precision, poor...
