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 Fluid : Max. 60 °C |
| Temperature effect | Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.6 % per 10 ℃ of full scale |
