Technical Data
Pneumatic
*Output Signal See product selector
*Air Supply Oil free, dry air, filtered to 5 microns; at least 0.7bar above maximum required output pressure range
*Flow Capacity Up to 300Nl/min (10scfm)
*Air Consumption < 4bar: 0.85 l/min (0.03scfm) typical
> 4bar: 1.75 l/min (0.06scfm) typical
*Response Time (dependent on input and output pressure) < 2bar/30psig: less than 0.5 seconds for 10-90% step change
> 2bar/30psig: 2 seconds for 10-90% step change
*Total Error +/-0.5% of span (typical, independent error includes the combined effect of non-linearity, hysteresis, deadzone and repeatability)
*Temperature Effect Typically better than 0.1% span/°C for span and zero over operating range
*Supply Sensistivity Better than 0.025% span output change per % supply pressure change
*Connections 1/4" NPT standard (others available on request)
Physical
*Operating Temperature -20°C to +70°C
*IP Rating IP65 in normal operation
*Electromagnetic Compatibility This is a passive electromagnetic instrument and is unaffected by interfering high frequency signals
*Material of Construction Zinc diecasting passivated and epoxy paint, nitrile diaphragms, stainless steel/nylon flapper nozzle and supply valve
*Mass 1500g
*Mounting Position Integral surface mounting bracket provided for preferred vertical mounting. 50mm pipe mounting kit available
Electrical
*Electrical Signal See product selector
*Failure Mode Signal falls to bleed pressure when electrical supply fails
*Connections 30mm square connector DIN 43650 provided, mountable in four directions (alternative connections available)


Certification

An intrinsically safe 100X model certified to CENELEC EN50 020 (BS 5501 part 7) EEx ia llC T4 is available (Installation with these models must comply with information given in BS 5345, parts 1 and 4)
All instruments are tested on the Watson Smith Automatic Testing System and an individual test certificate is provided at no extra charge. Each unit is tested for linearity, hysteresis, total error, settling error, over pressure, air consumption, response time, calibration, insulation, start-up current, supply sensitivity and voltage load.

Please note, this product is not yet RoHS compliant.
