• Fully welded 316 stainless construction
• 4:1 Downranging
• 4 to 20 mA output

Operating Pressure Ranges
Any zero based FS from 0.625 mH₂O to 700 mH₂O gauge
Standard Pressure Ranges

• The standard Upper Range Limit (URL) can be configured by the customer to any intermediate range determined by the Range Adjustment Limits.
• mH₂O: 2.5, 5, 10, 15, 20, 35, 50, 100, 150, 200, 350, 700

• Sensors can be provided with a pressure calibration at a down ranged FS, (e.g., 17 mH2O) at an additional cost (refer to Option C). Other units are software selectable e.g. mmH2O, ftH2O,inH2O, mbar, psi, bar.

Range Adjustment Limits

• Downranging (4:1) — full 4 to 20 mA output change for any user zero based span setting up to the Upper Range Limit (URL) from 25 to 100% (URL).
• Reverse (20 to 4 mA) — output can be inverted to give reducing current with increasing level, e.g. 0 to 10 mH₂O (0 to 15 psi) range provides a 20 to 4 mA output as a power saving feature.
• Elevation — the 4 mA output can be elevated within 0 to 75% of the Upper Range Limit (URL), e.g. 0 to 10 mH₂O (0 to 15 psi) range can be elevated up to 7.5 to 10 mH₂O (10 to 15 psi), with corresponding 4 to 20 mA output, e.g for water tower applications.

Overpressure
Standard Pressure Ranges (URL) can be exceeded by the following multiples with negligible effect on performance:

• 6 x for ranges to 2.5 mH₂O (4 psi)
• 4 x for ranges above 2.5 mH₂O (4 psi) (1400 mH₂O (2000 psi) max)

Pressure Containment

• 10 x for ranges to 2.5 mH2O (4 psi)
• 6 x for ranges above 2.5 mH2O (4 psi) (1400 mH2O (2000 psi) max)

• 3.8 to 20.5 mA proportional to the Loop Cal input in Remote Configuration Software (RCS) operation
