DESCRIPTION
The Model 3052 is a piezore si st ive silicon ac celerometer with
integral temperature compensation. It is packaged on a ceramic
su bst ra te w ith an ep ox y se al ed ce ra mic c ove r a nd is des ig ne d fo r
adhesive mounting.
The acceleromete r consists of a micro machined silicon
mass suspended by multiple beams from a silicon frame.
Pie zor e s ist ors loc at ed in t he be am s c hang e t hei r r es is ta nce a s t he
mo tio n o f the su spend ed ma ss ch an ges th e st ra in in t he be ams.
Sili con caps on the top and bottom of the device are added to
provide ove r-rang e stops. This design provides for a very low
profile, high shock res istance, durability and built-in damping
over a wide usable bandwidth. E ach sensor is individually
serialized.
F or a n acce ler ometer with a mounting br acket wh ich can be
used to bolt the sensor to the mounting location s ee the Model
3058. For uncompensated accelerometers, please refer to the
Models 3022 and 3028.

PERFORMANCE SPECIFICATIONS
Supply Volta ge: 5.0 VDC
Ambient Temperature: 25°C (Unless otherwise specified)
Notes
1. Actual test data for this parameter is included on the calibration sheet
included with each sensor. A sample of this calibration sheet is shown as
Figure 1.
2. The useful frequency range is defined as the range of frequencies over
which the device sensitivity is within ±5% of the DC value.
3. Positive voltage change for positive acceleration; negative voltage
change for negative acceleration.
4. For sensors having resonant frequency greater than 5 kHz, the
calibration data sheet will indicate “>5 kHz”. In addition, the damping
ratio will indicate N/A.
5. Best Fit Straight Line. For full scale ranges of 10g or less, the maximum
non-linearity is ±2%.
6. Compensated temperature range: 0°C to +50°C in reference to 25°C.
7. Prevents increase of TC-Span and sensitivity decrease due to output
loading.
8. 400g for ±2g, ±5g and ±10g versions, 20X or 2000g, whichever is
lower, for other versions.
