Seameterics Blind Analog Transmitter Controller-AO55 Series

for smoothing of the output signal. The degree of averaging can be selected in the feld, from 2 to 16 seconds.
For maximum environmental protection, the electronic components are encased in a special semi-fexible urethanepotting material. The housing is cast from aluminum and fuse-coated. The clamshell housing is connected directly to the fow sensor or, in the wall mount version, provided with mounting feet.
The AO55 will operate on a relatively wide range of current loop voltages, 24 to 36 Vdc. Lower voltages limit the load 
that can be applied to the loop without distortion of the signal. (See Load/Supply chart if there is a question regarding voltage vs. load.) A built-in power regulator supplies the appropriate power to the fow sensor. 
Typical applications for this transmitter are telemetry (or SCADA), distributed control systems, programmable controllers, data logging, and chart recording.
