75mm -0.1 MPa Flange Panel Mounting SS Case Brass Connection Vacuum Pressure Gauge
Description
The normal ambient temperature range for WESEN pressure gauges is -40oF to +140oF (-40oC to +60oC) for dry or silicone-filled gauges and -4oF to +140oF (-20oC to +60oC) for glycerine-filled gauges. The error caused by temperature changes is +0.3% or -0.3% per 18oF rise or fall, respectively. The reference temperature is 70oF (20oC). The correction is for the temperature of the gauge, not the temperature of the measured medium. Remote gauge mounting using a diaphragm seal and capillary line is one alternative for applications involving extreme ambient temperature.
Moisture and weather effects must also be considered. Liquid-filled gauges prevent condensation build up.
For outdoor use, stainless steel, brass or plastic cased gauges are recommended.
Applications
Practically all industries make use of vacuum, from pick and place in the automotive industry, food & beverage, manufacturing, pharmaceutical, chemical, nautical, etc. The vacuum gauges are important devices to ensure optimal performance and safety of the system. They may be used for pick-and-place applications, keeping the workplace clean from pollutants, transport materials, etc.
