Abstract: A "pressure" gauge which measures density of a gas in a vacuum system is temperature-compensated to give more accurate pressure readings by taking into account the actual gas temperature in the gauge as well as the temperature of the gas during calibration of the gauge. The calibration is for gauge output current versus measured gas pressures; during calibration, the gas temperature is also measured. During pressure measurement gas temperature is measured in the gauge and a microcomputer is used for computations and for lookup of calibration pressure values which nominally corespond to gauge output current values. The output current is first compensated for temperature correction by multiplying it by the actual absolute gas temperature and dividing the product by the absolute calibration gas temperature. This new temperature-compensated output current is used by the microprocessor to access the stored calibration data and to provide a temperature-compensated pressure value.

Abstract: A conversion circuit is provided which includes a negative temperature coefficient resistance between a rectifier and a storage capacitor to limit inrush current when power is applied to the circuit after a power interruption of a relatively long duration. When power is resumed after a short term power interruption and the resistance of the negative temperature coefficient resistance is still low, inrush current is limited by disconnecting a load from the conversion circuit immediately upon the occurrence of the power interruption to maintain the charge on the storage capacitor for the duration of the interruption. A boost regulator unit is provied between the negative temperature coefficient resistance and the storage capacitor to provide a regulated direct current potential across the capacitor which is not responsive to input power variations.
