DAS650

The aviation industry has an enormous need for more reliable and cost-effective tools for performing standard pitot-static system leak tests, FAR 91-411 and/or FAR 43 Appendix E certifications. These needs motivated Barfield to design and produce digital replacement instruments for the Barfield 1811 series and equivalent testers. The DALT55 Digital Altimeter and the DAS650 Digital Airspeed indicator were designed to be a direct replacement to the current analog instruments. Being of similar shape and size of existing analog instruments, the new digital version fits all Barfield 1811 series and most other manufacturers of analog pitot-static test sets. Standard analog instruments provided in a Barfield 1811 series or equivalent pitot-static tester are delicate mechanical devices easily damaged or destroyed by inexperienced or distracted technicians. The DALT55 and DAS650 use state-of- the-art transducer technology for pressure measurements making them virtually immune to the frequent and costly repairs generally associated with analog instruments.
