MKS - Model AA07B12PBB2GT1 -Micro-Baratron High Pressure Single-ended Pressure Transducers
The AA07B12PBB2GT1 Micro-Baratron® High Pressure, Ultraclean, Single-end Pressure Transducer offers a Full Scale measurement range of 100 psia with a 0.25 inch OD tube fitting, 0-10 VDC analog output, and LDM-C (Red LED), 0-5 VDC and 0-10 VDC with high density D connector in a standard 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 AA07B 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. The optional local integrated display provides a digital readout of the line pressure at the transducer. The display, which is available on the 1000 Torr, 100 and 250 PSIA ranges with the 0-10VDC output signal, provides a highly visible red LED display of the pressure and the units of measurement. The display can also be switched to show any of four different units (PSIA, Torr, bar, and kPa) without requiring recalibration or re-ranging of the transducer itself. It takes its power from the incoming transducer voltage, so no additional cables are required.
