Home Moldova Technologies Device for Measuring Pressure of Various Gases

Device for Measuring Pressure of Various Gases


The device is designed for measuring the air pressure in a range of 1·10–5 to 800 mm Hg. Pressure is measured using thermocouple pressure gauges TTC-1 (with a pressure conversion range of 1·10–5 to 1·10–1 mm Hg) and TTC-2 (with a pressure conversion range of 1·10–4 to 20 mm Hg) and using the strain pressure gauge TTR-1 (with a pressure conversion range of 10 to 800 mm Hg) employing one measuring channel.

Innovative Aspect and Main Advantages

The studies showed the possibility to use the device for measuring pressure of various gases or their mixtures, which significantly expands the application range of the device.

To study the calibration characteristics of the gauges comprising the device, we developed a gauge unit that employs Bayard-Alpert gauges, which can be used for preparing vacuum gauge systems for measuring pressures up to 1·10-8 mm Hg.

The wide range of pressure measurement, high accuracy combined with low cost in comparison with foreign counterparts, makes the pressure gauge attractive for import substitution.

Areas of Application

Domain of implementation: the electronics industry, chemical industry, food industry, metallurgy industry, scientific research, and deposition of coatings.

Stage of Development

Engineering documentation has been developed; a prototype sample has been prepared; and acceptance tests have been performed.

The tests were performed under production conditions in the factories "Vibropribor" and "Topaz."

Certificate of registration of industrial design no. 1353 of June 11, 2009 was obtained for the device.
