Determine the type of pressure gauge by its name
High Precision Digital Pressure Gauge "is a high-precision digital pressure gauge. This means that it is not a traditional mechanical pointer pressure gauge, but an instrument that uses digital technology to display pressure readings.
working principle
It usually contains pressure sensors inside, such as piezoresistive sensors, capacitive sensors, etc. When pressure is applied to the sensor, the sensor will generate corresponding electrical signals based on the magnitude of the pressure. These electrical signals undergo a series of processing steps such as amplification and analog-to-digital conversion (A/D conversion). For example, a piezoresistive sensor will change its resistance value according to pressure, thereby changing the current or voltage passing through it, and then convert this analog signal into a digital signal through an internal circuit, and finally display the pressure value in digital form on the screen.
Application scenario characteristics
In the field of industrial automation, high-precision digital pressure gauges can accurately measure the gas or liquid pressure inside pipelines on automated production lines. For example, in chemical production, precise control of the pressure inside the reaction vessel is crucial. This type of pressure gauge can provide real-time and accurate pressure data to ensure that chemical reactions proceed under appropriate pressure conditions.
Automobile manufacturing and maintenance: plays a role in the braking system, tire pressure monitoring, and other aspects of automobiles. Compared with traditional pressure gauges, it can more accurately measure the hydraulic pressure in the car's brake pipeline, helping engineers to precisely adjust the brake system pressure and ensure the reliability of the car's braking performance.
Aerospace field: The hydraulic and pneumatic systems of aircraft require high-precision pressure measurement equipment. This pressure gauge can accurately measure the air pressure in the aviation fuel system, hydraulic control system, and aircraft cabin, providing reliable data support for flight safety.
Laboratory environment: In physics, chemistry, and other laboratory experiments, high-precision measurement of gas or liquid pressure inside experimental equipment is carried out. For example, in physics experiments, when studying the equation of state of gases, it is necessary to accurately measure the pressure changes of the gas inside a closed container. This digital pressure gauge can meet the accuracy requirements of the experiment.
