Jewell Instruments LSM Specifications

LSM Series Accelerometer

Making Sense Out of Motion…

LSM Series Accelerometers
have 100,000 hour MTBF
reliability and up to 20g full
scale sensing range

If space is a concern, the Jewell

LSM Series accelerometer

is the solution for you. The LSM
offers equivalent features to the LSA

Outline Drawing: Dimensional Drawing for the LSM Accelerometer (inch/mm)

in a smaller package - approximately

1" cub. Its wide input range and
bandwidth features meet the
demanding needs of a variety of
aerospace applications.

Notes: 1 - Full range is defined as "from negative full input acceleration to positive full input acceleration."

2 - Nonlinearity is specified as deviation of output referenced to a best fit straight line,

independent of misalignment.

3 - Output phase angle = -90°

4-Unit Power connections can be easily adapted for operations from single-ended, floating power

supplies of 24 to 36 Volts DC.
