| 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). 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 |
| (With panel mounting plate,
3mm thick, black painted finish with corner fixing straps) |
| *SP |
Manostat regulator plus 63mm diameter
pressure gauge (phospher bronze Bourdon tube to BS1780); horizontal/vertical
mounting |
| *SP2 |
As SP model but with a rotary 2 position,
3-way auto/manual valve; horizonta/vertical mounting; pressure gauge indicates
manual set pressure only |
| *SP2G2 |
As SP2 model but with a second pressure
gauge to measure auto signal pressure before switching; horizontal/vertical
mounting |
| *SP2G2W |
Weatherproof SP2G2; surface/post
mounting (yoke supplied suitable for a 50mm/2" diameter post) |
| 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)
