The AA07A12PCB4GF4 Micro-Baratron® High Pressure, Ultraclean, Single-end Pressure Transducer offers a Full Scale measurement range of 100 psia with a 4 VCR male fitting, 4-20 mA analog output, and 6 ft. flying leads in a NEMA4 enclosure. It is ideally suited for use in delivery systems that feed ultrapure gases to critical process systems. Their wetted surfaces exposed to the gas stream have a finish of better than 5 µin Ra. These transducers exhibit superior dry-down characteristics, and contribute no particles above background. After manufacture and assembly, they are purged with ultraclean nitrogen prior to double bagging in a class 100 environment. The all-Incoloy® construction of the sensors in the AA07A allows for high overpressure tolerances that reduce errors due to line pressure spikes. High burst pressure ratings contribute to overall system safety. On existing gas cabinets and process systems, field replacement of common dial gauges or lower performance transducers is made easy due to the small size, industry standard end to-end lengths, and electrical interface choices of these transducers.
