SMC Pressure Gauge
A pneumatic gauge is a gauge for measuring the pressure of gas. Pneumatic gauges vary according to pressure span, system class and size. Select according to the operating environment. Usually, the 0 point of a pneumatic gauge is the atmospheric pressure. A gauge that displays values above 0 MPa is called a pressure gauge, a gauge that displays negative pressure is called a vacuum gauge, and a gauge that can display both is called a compound gauge. Select a pressure gauge according to the fluctuation of the target pressure. Selecting an incorrect gauge may damage not only the gauge, but also the target device. For this reason, some pneumatic gauges come with safety marks to prevent damage to the target device. When used for food processing applications, an easily removable pneumatic gauge must be selected because boiling water is sometimes used for hygiene management.
