The listed pressure ranges are also available in kg/cm2, kPa and MPa.
Special measuring ranges between 0 ... 10 and 0 ... 20,000 psi ( 0.4…1600 bar) are available on request.
Special pressure ranges may have reduced long-term stability and increased temperature errors.

Overpressure limit
The overpressure limit depends on the specific sensor element used for the selected pressure range. A reduction in the
overpressure safety rating may occur depending on the specific process connection and seal selected. A higher overpressure
limit may provide a greater temperature error.
