The next generation of MEMS-based low-range differential pressure sensors for HVAC applications is available. The sensors can be used to monitor clean, dry gas/air pressures and are available in pressure ranges of 0 to 1 inch, ±0.5 inch w.g., and 0 to 5 inches, ±1 inch w.g. The sensors operate on a 5-VDC power supply and provide a linear, amplified output of 0.25 to 4.0 VDC. The operating temperature range is 14° to 140°F (-10° to 60°C). These sensors utilize a variable-capacitance-on-silicon sensing technology and do not exhibit position sensitivity. They are intended to be PCB-mounted as part of a microprocessor-based control system or in a combination damper actuator/control system. Both models P992 and P993 have identical internal components.
