| *Output Signal | See ordering information. Pressure range can be limited by resetting the locknuts provided | |
| *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). High relief version available for applications requiring a rapid exhaust | |
| *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 Accuracy | % output change for 1bar/15psi supply 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 and Repeatability | Typically less than 0.05% setting at mid-range | |
| *Temperature Effect | Typically better than +/-1% change of full span between -20°C and +70°C | |
| *Connections | 1/4" NPT female standard (plus two integral 1/4" NPT gauge ports); others on request | |
| Model Types | ||
| *Handwheel | Basic manostat unit with pressure adjusting handwheel; mounting in any attitude, integral mounting nut supplied | |
| *Dial manostat | Manual pressure loading unit combining a manostat regulator with 4" diameter gauge | |
| *DIN manostat | As above but with a DIN standard pressure gauge | |
| *DMW | Weatherproof version of dial manostat with 100mm diameter gauge; pneumatic connections taken to lower face of casing; surface or post mounting (yoke supplied suitable for a 50mm/2" diameter post); casing is polycarbonate, grey finish to IP55 | |
| *Volume Boosting Air Relay (manual bias) | Remote control of regulated pressures is possible with minimal air usage; positive or negative bias between pilot signal and regulated pressure can be set up of up to 2bar/30psig | |
| Physical | ||
| *Operating Temperature | -20°C to +70°C | |
| *IP Rating | IP65 | |
| *Vibration | The unit is unaffected by moderate vibration | |
| *Material of Construction | Zinc diecasting passivated and epoxy painted. Berylium copper capsule; Nitrile diaphragms | |
| note: a small pressure (<2psig, 0.14bar) will show at the lower end of dial manostats gauge scale (due to regulator servo operation) | ||
