H igh output, industrial grade accelerometer
with integral hardline cable, and available
in two temperature ratings. Hermetic
construction is proof against degradation under
severe operating conditions including high
pressure fluid immersion. /F version is suitable
for milli g monitoring with appropriate
instrumentation.
High temperature vibration measurement may
be subject to increased noise level caused by
insulation resistance drop and high level of pyroelectric
charge generation, necessitating
bandwidth limitation. Low level measurement
threshold is determinated by wide band noise,
series and common mode electrical interference.
These can be minimised by choice of
instrumentation and transducer cabling.
Construction comprises electrically isolated
KONIC sensing element and all welded case and
case/cable seal for maximum measurement
integrity and reliability. Proof pressure testing
and elevated temperature burn in is
recommended where appropriate.
