vacuum gauge

On board the plane, he was watching the vacuum gauge with a tense frown.

One unique feature was a vacuum gauge on the instrument panel.

In other words, most low vacuum gauges that read, for example 50.79 Torr.

A thermocouple can be used as a vacuum gauge over the range of approximately 0.001 to 1 torr.

The thermocouple was first used as a vacuum gauge by Voege in 1906.

Today, however, these gauges have largely been replaced by electronic vacuum gauges.

The new center console housed a rally-type electric clock, and full instrumentation now included a vacuum gauge.

Instruments used to measure pressure are called pressure gauges or vacuum gauges.

He also invented a type of cold cathode vacuum gauge known as Penning gauge.

In 1874 he published a paper with a new and innovative vacuum gauge, this is known as the McLeod gauge.

Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties.

This would require a vacuum gauge measuring the pressure drop or abbsolute pressure at the sensor.

Also attached to this box were the vacuum gauge and a third pipe which led to what appeared to be a servo for the brake (?!).

Pressure gauge or vacuum gauge (see pressure measurement)

Buyers could now choose an Econominder instrument package that included a vacuum gauge to point out when optimum fuel economy was being attained.

The most common secondary transducers in modern vacuum gauges measure a change in capacitance due to the mechanical deflection.

Other MPT successful products include a vacuum gauge, microwave amplifier modulators and test equipment.

Now instrument-needles were moving all over the panel: oil pressure, vacuum gauge, ammeter, voltmeter, heading indicator, artificial horizon, navigation indicators.

In the following illustrations the transparent cover face of the pictured combination pressure and vacuum gauge has been removed and the mechanism removed from the case.

Chemistry World Sept 2011 McLeod's Vacuum Gauge.

To distinguish a negative pressure, the value may be appended with the word "vacuum" or the gauge may be labeled a "vacuum gauge."

In 1906, he made his most important invention with the development of a new type of vacuum gauge that today bears his name, the Pirani gauge.

A vacuum gauge is used to measure the pressure in a vacuum-which is further divided into two subcategories, high and low vacuum (and sometimes ultra-high vacuum).

By March 1904, the Syracuse Gauge Mfg. Company was producing gauges for ammonia, steam, brine, water pressure and vacuum gauges.

Dehmelt got inspiration from the vacuum gauge built by F. M. Penning where a current through a discharge tube in a magnetic field is proportional to the pressure.
