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
1) 1.7-fold overload safety with 1,000 psi, 1,500 psi, 4,000 psi and 6,000 psi
