    Abstract: A method and apparatus for measuring gas pressure by combining an ionization gauge with at least one other vacuum sensor. Nonvolatile memory coupled to the vacuum gauge contains calibration parameters unique to each individual sensor based on factory calibration. The nonvolatile memory may contain calibration parameters for a heat-sensitive vacuum sensor to compensate for the temperature gradients generated by the ionization gauge. The calibration parameters are a function of calibration data determined when the ionization gauge is both on and off. The nonvolatile memory may store a window of measurement data of the vacuum gauge that is updated at predetermined time intervals and in response to an event, such as an error event, to aid in investigating the cause of vacuum gauge malfunction or failure.

The inventive device comprises an assembly, which is integrated between the insulating core and the covering film of the thermal insulating board and which has a body that acts as a heat sink (3) (Al, Co, Fe, ceramic), and the body's thermal conductivity and thermal capacity relative to volume are greater than those of the insulating core. Said assembly also comprises a test layer (4) (0.3 mm nonwoven fabric made of plastic and glass fibers), which is arranged between the heat sink and the covering film and has a defined thermal conductivity that changes according to the gas pressure inside the evacuated thermal insulating board. From the exterior, a sensor device is applied to or pressed against the test device, which is placed inside the evacuated thermal insulating board and which is covered by the covering film. Said sensor device comprises a body (5) (coppered steel 78 DEG C, thermoelement (6)) having a distinctly different temperature than that of the test device (heat sink) whereby creating a heat flux, which is influenced by the thermal conductivity of the test layer, said thermal conductivity varying according to the gas pressure inside the thermal insulating board, and the magnitude of this heat flux is metrologically determined. The heat sink (3) can be provided in the form of a bottom part of a container for a getter material.

    Abstract: A miniaturized silicon based thermally controlled vacuum sensor (10) uses thin film resistors (not shown) on a membrane (20) in a minute measuring chamber (14) to accurately detect vacuum pressures in the range of 760 Torr to 1 x 10 Torr. The configurations of the measuring chamber (14) and gas diffusion port (19) of the sensor structure insure that heat transfer from the membrane (20) is predominantly conductive over the pressure detection range to provide linear output up to 0.1 Torr. A microprocessor (not shown) is used to control and measure power required to maintain a predetermined temperature differential between a sensing resistive element (not shown) on the membrane and an ambient temperature sensing element (not shown) of the sensor base (12) from analog voltage and current values. Pressure detection errors introduced by ambient temperature variations are minimized by measuring power dissipated into the gas. Analog and digital converters for both current and voltage signals use a SIGMA - DELTA conversion method to reject electrical noise by an averaging technique to produce stable signal detection of pressure down to 1 x 10 Torr. The sensor is thermally stable over an ambient temperature range of 0-50 DEG C at pressures between 10 to 760 Torr.
