Abstract: Various automated cleaning systems for internal cavities of pressure instruments are disclosed. The systems comprise a computer controlled fluid flow system that enables the use of various cleaning fluids for cleaning internal cavities of pressure instruments to high cleanliness levels. Various pressure instruments, including complex shapes such as Bourdon tube gauges, are accommodated. The system can include a computerized cleaning cycle selection and a multi-fluid combination of cleaners for efficient and low cost cleaning solution. A servo controlled agitation system can allow for filling, evacuation, and drying of aqueous solutions as well as high performance solvents for Oxygen Clean service.

Abstract: Various dry well temperature calibration systems, as well as other temperature control systems, are disclosed. The system can include a well configured to receive a unit under test, a heater configured to heat the well, and a temperature sensor configured to detect a temperature of the well. The system can include a helical airflow groove around the well. A venturi pump unit can be in fluid communication with the airflow groove. The venturi pump unit can be configured to draw a flow of air through the airflow groove, thereby cooling the well.
