Setra Systems Inc. has introduced the Model 730, a compact variable capacitance (capacitive) vacuum manometer, designed to support the pressure control requirements of semiconductor, food processing, petrochemical, pharmaceutical, process monitoring, and industrial vacuum applications.
Available in full-scale pressure ranges from 10 to 1,000 Torr, the Model 730 offers 0 to 5 VDC or 0 to 10 VDC output that is both linear with pressure and independent of gas composition. Its standard ±0.5% percent 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.
