CMC Series
1 / 4ページ

DATA SHEET Vacuum Measurement Compact, Unheated, Capacitance Manometers Used as the vacuum capacitance manometer of choice for thin-film processes, the Brooks® CMC Series capacitance manometers provide accurate total pressure measurement independent of gas composition. The CMC Series delivers exceptional performance over a wide range of operating temperatures, making it an alternative choice to larger premium performance unheated gauges. The CMC is 40% smaller in size than traditional unheated capacitance manometers. Ideal for Aggressive Applications The all-welded design and Inconel® wetted surfaces ensures reliable operation in even the most aggressive processes. The combination of precision components and a wide temperature compensated operating range allows the CMC to deliver best-in-class zero and span temperature coefficients for optimum measurement stability. Available for Typical Process Ranges The CMC Series is available in full scale ranges from 1000 Torr to 10 Torr and is an ideal upgrade for small form-factor capacitance manometers and an economical alternative to full-sized unheated capacitance manometers. 40% smaller than traditional unheated capacitance manometers The CMC Series delivers similar performance in a space saving, economic package. Robust all-welded construction Ensures optimum measurement repeatability compared to other designs that are prone to error inducing internal stresses that cause unpredictable variations in pressure measurement independent of gas composition. Optional high-accuracy calibration Delivers the accuracy of more costly premium unheated manometers. View CMC Series Product Page
