‘’RS.M/S’’ series
Stepping motor driven super precision regulator.
High sensitivity air pressure control of 0.1% F. S. sensitivity is possible！

■Features-High precision air regulating by sensibility 0.1%F.S., hysteresis ±0.1%F.S.]-Excellent especially in relief characteristics, pressure characteristics, flow
characteristics
Minimum relief pressure (relief sensibility) is 0.03kPa,0.004psi(theoreticalvalue).
-No readjustment of regulated pressure required even after long "down-time".
-RS.M/S keeps the setup pressure for a long term accurately after a setup.
Almost no pressure drop after setup.
-Five-phase stepping motor drive enables users slightly change the setup
pressure by 1 step driving. Further, micro-step driving achieves high pressure
resolution by 0.1kPa,0.01psi or less.
-It keeps setup regulated pressure even in case of sudden electricity outage.
