Model A Configurations

A _ _ _ _ - _ _

Series A1		The Series A1 is a low cost digital differential pressure gauge with numeric indication and optional 4-20 mA output.
Series A2		The Series A2 is similar to the A1, but includes a "process arch" of LED's across the top of the gauge to mimic the movement of an indicating needle.

Series A3		The Series A3 includes a programming menu that allows pressure, velocity, and flow readings along with configuration of setpoints and other parameters. The A3 is available with (2) SPDT relays, and a 4-20 mA output.
Series A4		The Series A4 is similar to the A3, but uses a much brighter easier to read OLED programming display in place of the LCD used on the A3. The A4 is also rated to lower temperatures than the Series A3.
Series A6		The A6 is similar to the A4, but has a 316L SS face and does not have a “process arch”.
