Welch Digital Vacuum Gauge

Besides the traditional vacuum gauges with mechanical sensors e g bourdon capsule gauge diaphragm manometers with electronical diaphragm sensors are well established piezo and capacitance gauges.

Welch digital vacuum gauge.

The pressure to be measured is separated by a diaphragm from a reference vacuum and compared to the latter. Atmospheric to 1 mbar besides the traditional vacuum gauges with mechanical sensors e g bourdon capsule gauge diaphragm manometers with electronical diaphragm sensors are well established piezo and capacitance gauges. The total range of scientifically useful vacuums extends from approx. It is a highly accurate full range digital millitorr gauge using field proven thermocouple vacuum sensor technology.

Welch model 1526 diagnostic vacuum gauge is a rugged portable vacuum measurement instrument designed specifically for the demands of field use. Printed from sargent welch website user. The diagnostic vacuum gauge 1515 is a portable vacuum measurement instrument designed specifically for the demands of field use. A physical measurement of the whole vacuum pressure range is not necessary.

1000 mbar atmospheric pressure down to 10 12 mbar the ultra high vacuum range. Particular sensors and gauges must be used for parts of the whole range rough high and ultra high vacuum.
