Silicon MEMS Accelerometer
Signal Conditioned Output
Temperature Calibrated
Low Cost, Lightweight
dimensions
The Model 4000A & 4001A
are
economical signal conditioned
accelerometers with integral temperature
compensation. The accelerometers
incorporate a 3rd generation silicon MEMS
sensor providing outstanding performance.
The accelerometers are packaged in a
rugged aluminum housing ideal for
transportation and instrumentation testing.
The signal conditioned output incorporates
a 2.5V reference that offers the user a
differential or single-ended output.
