Installation and Operation
Manual
The Sensocon A3 and A4 series of differential pressure controllers provide control
of low differential pressure applications for air and other compatible non
combustible gasses. These instruments have a large LED display for pressure
indication, a LCD or OLED display for programming and additional LED’s to
indicate % of output, setpoints and alarm status. The instruments are fully
programmable from the key pad face or by utilizing the Opti-Link™
communication port for no touch programming. Options for the instruments
include a 4-20 mA output, and improved accuracies. There is also a low cost
weatherproof cover available for outdoor applications.
