TECHNICAL DATA

Pneumatic

•Output Signal See ordering information. Minimum outlet pressure 0.1-0.14bar (1.5-2psig)

•Air Supply Oil free, dry air or other dry gases, filtered to better than 25 microns; at least 0.2bar

(3psig) above output pressure to a maximum of 10bar (150psig, 1000kPa)

•Flow Capacity Up to 300Nl/min (10scfm).

•Air Consumption 0.2 l/min (0.006scfm) at 1bar (15psig);

0.3 l/min (0.01scfm) at 1.7bar (25psig);

0.6 l/min (0.02scfm) at 4bar (60psig);

1.2 l/min (0.04scfm) at 8bar (120psig) (typical values at maximum supply pressure)

•Response Time less than 0.2 seconds for 50% load change

•Regulation % output change for 1bar/15psi supply Accuracy pressure change at mid-range output:

0.1% (0.14bar/2-25psi), 0.05% (0.14-4bar/2- 60psi), 0.02% (0.14-8bar/2-120psi)

•Sensitivity Better than 0.3mbar (0.005psi)

•Hysteresis Typically less than 0.05% setting at mid-Repeatability range

•Temperature Typically better then 1% change of full span between 20C and +70C

Effect

•Connections 1/4” NPT female standard (plus two integral 1/4” NPT gauge ports);

others available on request

Physical

•Operating Temperature -20C to +70C

•I.P. Rating IP65

•Vibration The unit is unaffected by moderate vibration

•Material of Zinc diecasting passivated and epoxy painted, Beryllium copper capsule;

Construction Nitrile diagraphms

Note: A small positive pressure (<2psig, 0.14bar) will always be shown at the lower end of the gauge

scale (due to regulator servo operation)

Model Types
