Advantages

01Filling fluid Halocarbon oil /100% O2 compatible

02All media wetted parts are cleaned oil grease free

03Improved EMC resistance and reduced installation sensitivity

04Linearized and temperature -compensated output signal

05Calibration of zero /Span and Turn -down

06It can be used in areas where there is a risk that the device will be exposed to high levels of pure Oxygen
