What Is a Digital Differential Pressure Gauge?
A digital differential pressure gauge is a device that measures and digitally displays the difference in pressure between two points. It is also known as a Manometer.
The major features are the simplicity of measuring differential pressure by simply connecting the two points to be measured and the digital differential pressure gauge with a measuring tube, as well as its small size and light weight.
There are many products that can measure both gases and liquids.
It has a wide range of measurable range and resolution, from relatively large differential pressure such as air pressure in air conditioning equipment to very small differential pressure in clean rooms , and is used for a wide variety of purposes.
Uses of Digital Differential Pressure Gauges
Due to their wide measurement resolution, digital differential pressure gauges can be used in a wide range of applications.
- Performance check of air conditioning equipment (ducts, fans, filters, etc.)
- Environmental measurement by checking minute differential pressure and dust collection effect in clean rooms
- Level measurement of large sealed tanks
- Other evaluation and testing applications such as airtightness tests
The battery-powered type, which requires no wiring, is used to monitor and record equipment, while the type with an alarm device is used for maintenance purposes such as filter replacement.
Principle of Digital Differential Pressure Gauges
Embedded inside digital differential pressure gauges are an element called a piezoelectric element (piezoelectric element).
When pressure is applied to the element, the deflection of the element is measured as displacement, and the displacement is converted to pressure using the relationship between the change in resistance due to the current flowing through the element and the displacement of the element. A digital differential pressure gauge displays the difference in pressure between two points measured in this way as a digital value. A digital differential pressure gauge displays the difference in pressure between two points measured in this way as a digital value.
Since the digital differential pressure gauges have two measuring points, it measures the magnitude and direction of deflection (displacement) caused by pressure applied from the two measuring points in two directions. By also measuring the direction, it can be determined which side is the high pressure side and which is the low pressure side, and the difference in displacement is read as an electrical signal and displayed as a pressure difference.
The piezoelectric element, which plays a key role in the measurement, consists of a piezoelectric material with a piezoelectric effect sandwiched between two electrodes.
Because of its simple structure, it is durable, resistant to deterioration, and easy to reduce weight.
There are many materials that have a piezoelectric effect, and materials for pressure-sensitive elements are being developed, so products capable of more precise measurement are also being developed.
