Content | WWW.MKSINST.COM Pressure Measurement & Control Types R740C, R750C BARATRON GENERAL PURPOSE CAPACITANCE MANOMETERS WITH TRIP RELAYS Today’s industrial manufacturing processes require stability, repeatability, and accuracy in measuring pressure and vacuum. MKS has applied its expertise in capacitance sensor design in the new Types R740C and R750C compact Baratron® capacitance manometers that are designed for use in industrial, analytical, and electronic measurement applications. The products’ flexible design allow it to be used either for new processing systems, or for retrofits into existing processing systems. The Types R740C and R750C Baratrons are rugged, industrial-grade pressure and vacuum transducers that are RoHS (Restriction of Hazardous Substances)-compliant and use MKS’ proprietary sensor and electronics designs for superior accuracy, repeatability, and long- term signal stability. All exposed sensor surfaces are made from Inconel® or Incoloy® nickel alloys for exceptional resistance to corrosion from a wide variety of agressive chemicals. The sensor is also fully welded, guaranteeing safety to equipment operators from accidental exposure to dangerous chemicals. This advanced sensor and its electronics are mounted in a rugged stainless steel enclosure that can withstand harsh environments, the two (2) independently-adjusted electromechanical trip relays allow the product to be used to directly control external components such as pumps, valves, and other equipment. All products meet applicable CE and RoHS Directives, and the trip relays are UL-listed for safety. The Type R740C product is referenced to atmospheric pressure, and thus offers full-scale measurements ranges from 20 to 3000 PSIG (1.4 to 204 bar). The Type R750C is an absolute transducer (referenced to high vacuum), and thus offers full-scale measurement ranges from 10 Torr (13 mbar) to 3000 PSIA (204 bar). The products have a standard linear 0-10VDC analog output signal in addition to the trip relays. Features & Benefits • Self-contained sensor and signal conditioner in a compact and rugged enclosure • All-welded Inconel® sensor construction allows for use with most corrosive media • Proven MKS capacitance technology yields a measurement resolution of 1 part in 10,000 • Linear 0-10VDC analog output plus two (2) independently-adjusted trip relays • Overpressure limit of two times Full Scale or 45 psia (whichever is greater) with no degradation in performance • Available with absolute (referenced to vacuum) or gage (referenced to atmo- sphere) calibrations • CE and RoHS (Restriction of Hazardous Substances) compliant |
