Pressure)
From 3.45 kPa abs. (0.5 psia)* to:
5 bar (70 psi) for range 0
80 bar (1200 psi) for range 1
160 bar (2300 psi) for ranges 2, 3 & 4
320 bar (4600 psi) for models H2 to H4
400 bar (5800 psi) for range 5
520 bar (7500 psi) for range 6
Flange Test Pressure: 60 MPa (8570 psi)
For ANSI/DIN Level flanges (LD303L models):
150lb: 6 psia to 230 psi (-0.6 to 16 bar) at 38 °C (100.8 ºF)
300lb: 6 psia to 600 psi (-0.6 to 41 bar) at 38 °C (100.8 ºF)
600lb: 6 psia to 1200 psi (-0.6 to 83 bar) at 38 °C (100.8 ºF)
PN10/16: - 60 kPa to 1.4 MPa at 120 °C (248 °F)
PN25/40: - 60 kPa to 4 MPa at 120 °C (248 °F)
The above pressures will not damage the transmitter, but a new calibration may be necessary.
