Model 730 Capacitance Manometer (CDG)

Brand: Setra Systems, Inc

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 provides 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.
Features
  • Tensioned diaphragm provides superior performance
  • Wide compensated operating temperature
  • Fast response time with low circuit noise
  • Insensitive to environmental changes
  • Exceptional overpressure capability
  • CE and RoHS compliant
