DWYER Differential Pressure / Pressure / Vacuum
Differential Pressure Gauge/Indicator: It measures the pressure difference between two pressure measuring points, rather than the absolute/relative pressure at a single point. It can directly reflect the pressure loss, liquid level difference, and degree of filter blockage of the medium in pipelines and equipment.
Pressure Gauge: It measures the relative pressure (gauge pressure) at a single measuring point. Taking atmospheric pressure as the reference, it shows the actual pressure value of the medium. It is the most basic pressure monitoring instrument in industrial/medical scenarios.
Vacuum Gauge: It measures the pressure value in a vacuum state (pressure lower than atmospheric pressure), and units such as Pa, mbar, Torr, etc. are commonly used. It accurately reflects the degree of vacuum in a closed space.
