SUS Pressure Gauge 100mm Dial ABS Lens 100mm Vacuum Manometer
100mm Vacuum Manometer Brass Connection Electric Contact Pressure Gauge
Description
When the atmospheric pressure within an enclosure is below ~14.7 PSI, that enclosure is said to be a vacuum. It is impossible to artificially achieve a pressure of zero, and there are no examples of absolute vacuums in nature or in space. An enclosure can, however, be partially evacuated of its contents. Vacuum gauges are used to measure the extent to which enclosures have been evacuated; they measure low pressure, not negative pressure. Vacuum gauges are made from metal such as stainless steel or aluminum.
Applications
Control and regulation of industrial processes
Monitoring of plants and switching of circuits
For gaseous and liquid media that are not highly viscous or crystallising and will not attack copper alloy parts
Special features
High reliability and long service life
Up to 4 switch contacts per instrument
Instruments with electronic contacts for PLC applications
Contact gauges comply with DIN 16085
