Période

1990's

Canada

Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).

Fonction

An instrument that measures atmospheric pressure and indicates the results in a digital format, used in the calibration of pressure measuring instruments.

Technique

An example of a precision calibration instrument used in a laboratory to verify air pressure reading instruments. This instrument detects pressure and displays the results as inches of mercury or millibars, or the equivalent feet or meters of altitude. It is a single channel monitor designed to provide high-precision indication of input pressure over the range utilizes by altimeters, air speed indicators, air data computers or other pressure devices. . This instrument contains an absolute pressure quartz transducer, which is extremely insensitive to attitude and the type, density or humidity of the operating gas. It tolerates environmental extremes as well as shock and vibration. It contains a 8085AH microprocessor with 512 bytes of RAM provided by two Intel 8155H chips.According to its manufacturer, this instrument closely approximates accuracy capabilities of commonly available industrial secondary standards (Ref. 1). In 1936, Cliff Garrett founded a company which came to be known as Garrett AiResearch or simply AiResearch. Garrett AiResearch designed and produced a wide range of military and industrial products for aerospace and general industry (Ref. 2).
