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

These listing is for an MKS Type 722C general purpose capacitance manometers having a 9-pin D-subminiature signal connector, a 20,000 Torr full scale maximum vacuum pressure reading value, a VCR 4 female vacuum flange connection, and have MKS part number 722C24TCD2FA.

Compatible Controller and Cables:

• P102061 - MKS PDR 2000 Power Supply and Digital Readout Cable 9-Pin Cable CB2000S-2-M1
• P102062 - MKS PDR 2000 Digital Power Supply and Digital Readout Capacitance Manometer Controller
• P1010127 - Ideal Vacuum Dual Capacitance Manometer Controller (DCM), Power Supply and Digital Pressure Readout

Product Features:

• 0 to 10 VDC proportional analog output with 9-pin D-sub connector
• Direct measurement of chamber total pressure independent of gas type or composition
• High accuracy over a wide operating temperature range
• Overpressure limit of 45 psia or 2x Full Scale (whichever is greater) assures no degradation in zero repeatability or performance
• All wetted sensor surfaces are micro-finished to =10 Ra, eliminating inclusion sites for corrosion growth
• Smaller manometer size helps achieve overall system size reduction
• Corrosion resistant - all-metal, all-welded con­struction exposes only Inconel and stainless steel to the media
• Drop in replacement compatible with earlier 722 Baratron capacitance manometers
