1) Only available with throttle element
2) With marine approval DNV-GL
3) Only available for versions with 250, 315, 400 and 630 bar
4) Highly dynamic effects in like pressure peaks or cavitation in hydraulic systems may damage the measuring cell. For these applications, devices with integrated throttle element [version "-N"] in the process interface have to be used.
