In summary, the conversation discusses a paper about the use of V-2 rockets for high-altitude research at White Sands, New Mexico. The paper mentions different gauges for measuring atmospheric pressure and the challenges of covering a pressure range of 108 mmHg. One of the gauges mentioned is the Philips Gauge, which is believed to be a cold cathode gauge similar to a Penning gauge. The conversation also suggests doing a Google search for more information on the Philips Gauge.

Hello,

I have read an interesting paper from the Proceedings of the American Philosophical Society about the use of the V-2 rocket at White Sands, New Mexico for high-altitude research. In it the different gauges for atmospheric pressure measurement were mentioned, as well as the difficulty to cover a pressure range of 108 mmHg.

The article then went on by explaining that the pressure is first measured by a bellows gauge, then by a Pirani gauge. For the lowest pressures either ionization or "Philips" Gauges would be used. I would like to know what a Philips Gauge is, because I did not find information on that on the Internet.

Thank you!

Related to What is a Philips Gauge and How Does it Work for Measuring Pressure?

1. What is a Philips Gauge?

A Philips Gauge is a type of pressure gauge used to measure the pressure of a gas or liquid. It was invented by Dutch physicist, Johannes Philips, in the late 19th century.

2. How does a Philips Gauge work?

A Philips Gauge works by measuring the deflection of a thin, corrugated metal diaphragm when pressure is applied to it. This deflection is then converted into a pressure reading using a calibrated scale.

3. What are the different types of Philips Gauges?

There are two main types of Philips Gauges: the Bourdon Tube Gauge and the Diaphragm Gauge. The Bourdon Tube Gauge uses a curved tube to measure pressure, while the Diaphragm Gauge uses a flexible diaphragm.

4. What are the common applications of Philips Gauges?

Philips Gauges are commonly used in industrial and laboratory settings to measure the pressure of gases and liquids in various systems such as pipelines, tanks, and machinery. They are also used in scientific research and experiments.

5. How accurate are Philips Gauges?

The accuracy of a Philips Gauge depends on various factors such as the type of gauge, the quality of its construction, and the calibration process. Generally, Philips Gauges have a high level of accuracy and can measure pressure within a few percentage points of the actual value.
