Highest sensitivity multiple shear plate vibration transducers intended for
micro g level measurement – virtual immunity to strain input side effects
provides guarantee of low frequency, measurement integrity. System nose level
of 10-2pC is equivalent to 1mg. With bandwidth restricted to 1 kHz, noise floor
should be significantly below this. Bear in mind that charge amplifier noise
increases as a function of input capacitance – noise assessment should be made
with the charge amplifier input correctly terminated. The transducer adds mass
at its point of attachment to a structure, thus imposes a transparency
constraint above which data corruption will be excessive. The single degree of
where MT represents the transducer mass, reduces by 3% for a
transducer adding 10% to the structure mass. Application area of the A/800 is
thus limited in scope to low level vibration surveys in the civil engineering
and heavy engineering domain
This Accelerometer is also available as an IEPE version -A/1800.
All DJB Accelerometers are calibrated on site prior to despatch, and are accompanied by a calibration chart with temperature and frequency responses listed.
Periodic calibration can be carried out with our VC-01 Handheld Calibrator whilst we also offer a full calibration service including cross axis checks to aid accuracy of data.
We are able to provide this service for all makes of accelerometer with a full report given for each device. Please contact us with an enquiry
