1. If the process can trip to a pressure outside of the operating range of the sensing element, a commercially available device, such as an overpressure protector, may be used to
protect against pressure surges and pulsations.
2. Range marked on Bourdon tube may be in kPa (1 bar = 100 kPa)
3. Bourdon tube may be pressurized to limit shown without permanent zero shift.
4. With travel stop set at 110% of the range.
5. Bourdon tubes are also available in NACE compliant material. Contact your Emerson Process Management sales office for additional information.

1. If the process can trip to a pressure outside of the operating range of the sensing element, a commercially available device, such as an overpressure protector, may be used to protect against
pressure surges and pulsations.
2. Bellows may be pressured to limit shown without permanent zero shift.
3. Transmitter only.
4. Except transmitter.
5. The overrange limit for these sensing elements is a differential pressure equal to the maximum allowable static pressure limit.
