概要（Overview）

The MKS Baratron® Type 622A, 626A, 627A, 628A, and 629A Absolute Pressure Transducers are part of the MKS family of general purpose pressure transducers designed to provide accurate, reliable, and repeatable pressure measurements in the range from 1K Torr to as low as 0.05 Torr F.S. (627 and 629). These instruments operate with ±15 VDC (±5%) input @ 35 mA, 250 mA, or 500 mA, depending upon the unit, and provide 0 to 10 VDC output linear with pressure. All instruments expose only Inconel to the process permitting use with corrosive or dirty gases and eliminating contamination of the process with transducer materials. Measurements are independent of gas composition and all of the units have a minimum measuring range of four decades.
