1. Today, however, these gauges have largely been replaced by electronic vacuum gauges . 2. This contains a concrete footing, switchboard, control panel switchboard, and a vacuum gauge . 3. In other words, most low vacuum gauges that read, for example 50.79 Torr. 4. One unique feature was a vacuum gauge on the instrument panel. 5. This can be seen on boost / vacuum gauges . 6. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. 7. This would require a vacuum gauge measuring the pressure drop or abbsolute pressure at the sensor. 8. The new center console housed a rally-type electric clock, and full instrumentation now included a vacuum gauge . 9. In 1874 he published a paper with a new and innovative vacuum gauge , this is known as the McLeod gauge. 10. By March 1904, the Syracuse Gauge Mfg . Company was producing gauges for ammonia, steam, brine, water pressure and vacuum gauges .
