Special features
Measuring ranges from 0 ... 0.1 to 0 ... 6,000 bar [0 ... 3 to 0 ... 15,000 psi]
Approved for use in hazardous areas, e.g. ATEX, IECEx, FM and CSA
Overload safety
The overload safety is based on the sensor element used. Depending on the selected process connection and sealing,
restrictions in overload safety can result.
A higher overload safety will result in a higher temperature error.
Measuring ranges ≤ 25 bar [≤ 400 psi]: 3-fold
Measuring ranges 40 ... 600 bar [500 ... 8,000 psi]: 2-fold 1)
Measuring ranges ≥ 1,000 bar [≥ 10,000 psi]: 1.15-fold
