Service intended
P440 series are designed to measure low, vacuum or compound pressure. These models have beryllium copper element and nickel plated steel case.
| Nominal diameter |
63, 75 and 100 mm |
| Accuracy |
±1.5 % of full scale |
| Scale range (kPa, mbar) |
-50 ~ 0 to -5 ~ 0 kPa
-15 ~ 15 to -2.5 ~ 2.5 kPa
0 ~ 5 to 0 ~ 50 kPa |
| Working pressure |
Steady : 75 % of full scale
Over range protection : 130% of full scale |
| Working temperature |
Ambient : -20 ~ 60 °C
