Indicating Ringbalance
measuring draft, pressure and differential pressure of gaseous mediums.
Measuring Principle
Ringbalance system, factory-filled ringbody, supported by ball bearings
Measuring Ranges
from 0-50 Pa (0.2" W.C.) to 0-1.8 kPa (7" W.C.)
also plus/minus ranges, such as -25/0/+25 Pa
Scale units
Pa, daPa, kPa, mbar, mmWS, mmW.C.; in.W.C.
Accuracy
max. error +/-1.5% of span, below 100 Pa: +/-1.5 Pa
Pressure Connections
2 fittings for flexible tubes, 8mm outside diameter
Housing
for wall mounting or panel mounting, made out of glass reinforced black polycarbonate, protection class IP40 (optional IP55)
Weight: 2.8 kg
Temperature
operating temperature 0...50°C (32...122 °F)
