1. Range marked on Bourdon tube may be in kPa (1 bar = 100 kPa).
2. Bourdon tube may be pressured to limit shown without permanent zero shift.
3. With travel stop set at 110% of the range.
4. Bourdon tubes are also available in NACE compliant material. Contact your Emerson Process Management sales office for additional information.

1. Bellows may be pressured to limit shown without permanent zero shift.
2. C1B transmitter only.
3. Except C1B transmitter.
4. The overrange limit for these sensing elements is a differential pressure equal to the maximum allowable static pressure limit.
