FAQ
Q Absolute, gauge or differential?
A
Absolute (abs): referenced to vacuum (atmospheric storage tank level). Gauge: referenced to atmosphere (compressed air, hydraulics). Differential (dp): between two points (flow, filter clogging, level). dp is most complex — dual diaphragm + impulse lines.
Q HART or IO-Link?
A
HART: analog 4-20 mA + digital overlay — 30-year process tradition. IO-Link: pure digital — discrete automation. Process → HART; machine automation → IO-Link.
Q Why is E+H Cerabar reliable?
A
Wide ceramic and metal diaphragm options; DAT module plug-and-play + adaptive zero-drift compensation; full ATEX/IECEx coverage; HistoROM backup; typical 10+ year life.
