Setra’s Model 730 is a high-accuracy absolute capacitance manometer (also referred to as Capacitance Diaphragm Gauge (CDG)), for measuring low vacuum pressure ranges that are critical to the control of processes in photovoltaic, semiconductor, and industrial markets. The 730 utilizes welded, all Inconel® wetted components which provide capability with the most aggressive process media. Its high-frequency electronics design is fully RoHS compliant and yields extremely low noise while maintaining the fast response time required for today’s critical control applications. External noise rejection, fast warm-up, resistance to environmental effects, and long-term stability are unmatched by competing models.


Key Benefits

  • High Performance For Demanding Applications
    The Model 730 capacitance manometer uses a rigid single-electrode variable capacitance sensing element resulting in high over-pressure capability and superior long-term stability. Its percent of reading accuracy, low hysteresis, and high resolution provides a wide dynamic range, making the 730 an ideal fit for measuring and controlling critical manufacturing processes.
  • Process-compatible Inconel® Sensor
    The 730 is designed using Inconel® for all its wetted parts. Inconel® is highly resistive to the corrosive media used in semiconductor and industrial vacuum processes. Their material, along with the all-welded construction, ensures long life in the most demanding applications.
  • Direct Pressure Measurement
    Unlike some vacuum measuring technologies, the Model 730 capacitance manometer measures direct pressure; force/unit area. Its 0-5 or 0-10 VDC analog output signal is proportional to the applied pressure and independent of the process gas composition.
