Supply
Pressure
Factory-configured.
20 psi (approximately 140 kPa, 1.4 bar) nominal.
35 psi (approximately 241 kPa, 2.41 bar) nominal. 35 psi required for 3-27 psig output units.
Filtered, regulated, instrument-quality air only. 20 psi units accommodate up to 30 psi without
damage. 35 psi units accommodate up to 40 psi without damage.
Controls
Span: Multiturn pot electronically adjusts full-scale output to 100% of rated span.
Zero: Multiturn adjustment screw mechanically provides offsets of ±3% of span.
Performance
Accuracy:
Error less than 0.5% of span, including the combined effects of linearity,
hysteresis, and repeatability. For 3-27 psig output units or 10-50 mA input units, error not to
exceed 1% of span. Linearity defined per SAMA standard PMC 20.1-1973.
Ambient Temperature Effect:
±0.1% of span per °C change within the rated ambient
temperature operating range (less than ±0.055% of span per °F change).
Supply Pressure Deviation Effect:
Maximum of 0.3% per 1.4 psig change
(0.3% per 0.1 bar).
Mounting Position Effect:
Negligible. Unit should be calibrated in final orientation.
RFI/EMI Effect:
±0.1% of span in field strengths of 10 V/m at frequencies of 20-500 MHz.
Step Response:
0.3 seconds into 100 ml (6 cu in) at 90% of span.
Pneumatic
Load
Air Capacity:
1.4 scfm (approximately 2.7 kg/hr)
Air Consumption:
0.1 scfm (approximately 0.2 kg/hr) dead-ended.
Environmental
Ratings
Recommended Ambient Temperature Operating Range:
–20 to 60 °C (–4 to 140 °F).
Weight
Approximately 800 g (1 lb, 12 oz)
