Q1: What is the FUJIKURA RS・M/S Series?
A: The RS・M/S Series is a five-phase stepping motor-driven super precision regulator for high-resolution air pressure control.
Q2: What pressure ranges are available?
A: RS・M/S-4-2 has a set pressure range of 0.014 to 0.42MPa, while RS・M/S-8-2 covers 0.014 to 0.84MPa.
Q3: What pressure control accuracy does it provide?
A: Sensitivity is 0.1% F.S., and hysteresis is ±0.1% F.S.
Q4: What pressure resolution is available?
A: Resolution is 1kPa or less with full-step operation and 0.1kPa or less with micro-step operation.
Q5: Is pressure readjustment required after extended downtime?
A: No. The regulated pressure does not require readjustment after extended downtime.
Q6: Is the set pressure maintained during a power failure?
A: Yes. The preset regulated pressure is maintained during a sudden electricity outage.
Q7: What is the minimum relief pressure?
A: The theoretical minimum relief pressure is 0.03kPa.
Q8: What working fluid is used?
A: The regulator uses clean compressed air.
Q9: What are the pipe and gauge port sizes?
A: Both the pipe port and gauge port are Rc1/4.
Q10: What applications is the RS・M/S Series suitable for?
A: It is suitable for applications requiring pressure resolution of 0.1kPa or less, including buffer, balancer, press, rolling, and tension control.
