  • Thermal insulation system for a capacitance diaphragm gauge
    Patent number: 12313488
    Abstract: A capacitance diaphragm gauge (CDG) assembly includes a CDG sensor positioned within a vacuum enclosure, which is maintained at a vacuum. The CDG sensor generates sensor signals responsive to a pressure of an applied gas. The vacuum enclosure provides thermal insulation around the CDG sensor. The CDG sensor is maintained at a selected operating temperature using an internal heater positioned on the CDG sensor. The internal heater is responsive to external heater control signals. The temperature of the CDG sensor is monitored using an internal temperature sensor mounted on the CDG sensor. The temperature sensor generates a temperature signal. The vacuum enclosure includes an end cap that seals the vacuum enclosure. Connectors positioned through the end cap communicate the sensor signals, the heater control signals and the temperature signals through the end cap. The connectors are hermetically sealed to the end cap to maintain the vacuum within the vacuum enclosure.
