The Model 805 is a miniature adhesive
mount IEPE accelerometer built on a 3-pin TO-5
header. It is available in ±50g and ±500g
dynamic ranges and offers a flat frequency
response to 15kHz. The accelerometer features
a hermetic construction in a TO-5 header
configuration. The model 805 incorporates a
stable piezo-ceramic crystal and an integrated
charge converter amplifier in a 100% shielded
housing suitable for many embedded OEM
applications.
The accelerometer is offered in two
configurations; one for adhesive mounting and
one for stud mounting.
