Kistler Model 8305A K-Beam® Capacitive Accelerometer Series
The 8305A K-Beam accelerometer series
utilizes a three layer silicon micro-machined variable capacitance sensing element designed for measurements of low level
acceleration in a steady state or low frequency environment. They are fully calibrated sensors with all excitation and signal
conditioning electronics integrated into a single package. K-Beam accelerometers provide a high level output signal with
excellent long-term stability. They are insensitive to thermal transients and transverse acceleration.
The 8305A(X)
standard configuration, provides the convenience of a single polarity power supply and a single-ended output. A 2.5 volt
offset is present at 0g. The 8305A(X)M4 and 8305A(X)M7 versions add a 4-point (pos. and neg. respectively)
connector to the cable end of the standard 8305A. The 8305A(X)M2 versions, operate from a single polarity supply
and provides a differential output. When connected to a different amplifier, the offset at 0g is nominally 0 volts.
Power can be furnished from a regulated DC power supply or from a 9-volt alkaline battery. The K-Beam accelerometers are
available either in a standard 0.5 meter length or in a user specified cable length. The 8305A series accelerometers are
housed in a sturdy, environmentally protected, anodized aluminum case with mounting flanges.
