DESCRIPTION
The Model 3022 is a piezoresistive silicon accelerometer. The
package is a ceramic substrate with a sealed ceramic cover.
The ceramic provides an excellent bonding surface for the
customers application specific adhesive. Each accelerometer
includes a detailed calibration sheet, which provides test data
and resistor compensation values for each sensor.
The accelerometer consists of a micro machined silicon
mass suspended by multiple beams from a silicon frame.
Piezoresistors located in the beams change their resistance as
the motion of the suspended mass changes the strain in the
beams. Silicon caps on the top and bottom of the device are
added to provide over-range stops. This design provides for a
very low profile, high shock resistance, durability and built-in
damping over a wide usable bandwidth. Each sensor is indi-
vidually serialized.
For an accelerometer with a mounting bracket designed to
bolt the sensor to a mounting location, see the Model 3028.
Please refer to the Models 3052 and 3058 for accelerometers
with integral temperature compensation.

Accelerometer Selection Guide–Unamplified
• Rstc sets the excitation voltage ramp to compensate the sensitivity
error due to temperature.
• Rset sets the excitation voltage to 5V at 25°C.
• Rzb1, Rzb2 and Rztc1 and Rztc2 calibrate the zero offset and
compensate the offset error due to temperature.
• Rs calibrates the output span.
• Vcc must be >8 VDC.
