Variable Capacitance Vacuum Manometer

Setra Systems Inc., a leading global designer and manufacturer of pressure measurement instrumentation for industrial, test and measurement, HVAC/R, semiconductor, energy, environmental, medical, pharmaceutical, and meteorological requirements, has introduced Model 730, a compact, low-cost Variable Capacitance (Capacitive) Vacuum Manometer, designed to support the critical pressure control requirements of semiconductor, food processing, petrochemical, pharmaceutical, process monitoring and industrial vacuum applications. Available in full-scale pressure ranges from 10 torr to 1000 Torr, Model 730 offers 0 to 5 V DC or 0 to 10 V DC output that is both linear with pressure and independent of gas composition. Its standard ±0.5% per cent of reading accuracy, with option for optimization to ±0.25%, ensures a wide dynamic range, along with negligible temperature coefficients across its 0 to +50°C compensated range, making units relatively insensitive to thermal transients and environmental changes. Temperature coefficients of ±0.25% of reading/+50°C on zero; and ±1.35% of reading/+50°C on span are standard. Units operate from a standard 12 to 30 VDC power source and can be configured with a 9- or 15-pin D-sub or 5-pin terminal strip electrical connection, all with “plug-and-play” industry standard pin-outs. A variety of vacuum fittings and interconnecting cables are also available. Occupying the same footprint as other industry manometers, the Model 730 may also be used as a seamless drop-in replacement in legacy applications where optimized performance is desired.
