722BGeneral Purpose Absolute 			Baratron® Capacitance ManometerToday’s process environments require small-sized pressure measurement instruments that provideaccurate, repeatable, and reliable measurements at a lower cost. MKS has applied its expertise incapacitance manometer design and manufacturing technology to the development of the compact,722B general purpose absolute Baratron® capacitance manometer. The flexible design of the 722Bmakes it an ideal solution for retrofit applications as well as new equipment designs.
Robust sensor construction provides high overpressure tolerances, reducing errors causedby occasional line pressure spikes. All sensor wetted surfaces are made from Inconel® toensure maximum compatibility with many process gases1. Sophisticated technology andstrict process controls ensure clean, smooth finishes (≤10 Ra) on all wetted surfaces. Signalconditioning circuitry is assembled using the latest techniques in surface mount technology.
All transducers are backed with a full two-year warranty.

Product Features• Signal output of 0-10 VDC or 0-5 VDC available• Full Scale range as low as 1 Torr• High accuracy over a wide operating temperature range• Overpressure limit of 45 psia or 2x Full Scale (whichever isgreater) assures no degradation in zero repeatability or 		performance• All wetted sensor surfaces are micro-finished to ≤10 Ra,eliminating inclusion sites for corrosion growthZEROZEROSPANSPAN1.50 DIA(38.1 mm)1.50 DIA(38.1 mm)0.40(13.7 mm) MAX.
