CASE DIAMETER
100 or 150 mm
ACCURACY
Class 1
SCALE RANGES
From 0...0.6 bar to 0...1600 bar (or similar in other pressure units)
PRESSURE LIMITS DURING OPERATION
Continuously: steady pressure up to F.S. value, fluctuating pressure 90% of F.S. value
Temporarily: 1.3 x F.S. value for ranges up to 60 bar or 1.15 x F.S. for ranges from 100 bar to 1600 bar
TEMPERATURE LIMITS
Ambient: -40 to +60 °C (without liquid filling) and -20 to +60 °C (with liquid filling)
Process: maximal fluid T° is 200 °C (without liquid filling) and 100 °C (with liquid filling)
DRAFT DUE TO THE TEMPERATURE
When the measuring system T° is different from the reference T° (+20 °C) the draft is 0.4% / 10 K of true scale value, as a maximum.
