Series
634S pressure transmitters
sense a single positive pressure and convert it into a 4-20 mA output
signal. Ten field adjustable models cover any range from 0-10 to
0-6000 psi. Zero and span controls are easily accessible yet fully
protected within side housing. Cable gland accepts .10-.25" I.D.
round cable. Tough filled nylon case includes integral holes for
surface mounting. Positive pressure can be measured within an accuracy
of ±2% of span (634S2) and ±1% of span (634S1).
