Overpressure limit

The overpressure limit is based on the sensor element used. Depending on the selected process connection and

sealing, restrictions in overpressure safety can result. A higher overpressure limit will result in a higher temperature

error.

Measuring range < 10 bar/150 psi ≥ 10 bar/150 psi
