US 6,308,574 B1 · Measuring device to measure the pressure of an atmosphere

Abstract

A measuring device is proposed to measure the gas pressure of an atmosphere, whereby the measuring device is provided with a sensor to measure the pressure located in the interior of a housing which encloses the sensor. In addition a unit to control the measuring device and to evaluate the signals as well as a supply unit are installed in this housing. The housing itself is sealed off against the surrounding atmosphere and is provided with contacts on the housing for the exchange of data between the measuring device and a unit for the evaluation of measured values connected to it. The contacts are provided at the same time to ensure that the unit for the evaluation of the signal of the pressure sensor can be supplied with control signals from outside the housing.
