| Model 3052 * Vibration/Shock Monitoring PC Board Mountable Accelerometer Millivolt Output Integral Temperature Compensation * Modal Analysis * Motion Control * Crash Testing * Aerospace DESCRIPTION The Model 3052 is a piezoresistive silicon accelerometer with integral temperature compensation. It is packaged on a ceramic substrate with an epoxy sealed ceramic cover and is designed for adhesive mounting. 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 individually serialized. For an accelerometer with a mounting bracket which can be used to bolt the sensor to the mounting location see the Model 3058. For uncompensated accelerometers, please refer to the Models 3022 and 3028.

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: 0C to +50C in reference to 25C. 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.
