PCB Piezotronics 303A Series Manual

MINIATURE 2GRAM
QUARTZ ACCELEROMETER
Series 303A
with built-in microelectronics & 10 mV/g sensitivity
Measure shock and vibration in applications requiring small size,
low mass or very high frequency response.
Series 303A Quartz Accelerometers function to transfer
shock and vibratory motion into high-level, low-impedance (100
ohm) voltage signals compatible with readout, recording or
analyzing instruments. These tiny sensitive (10 mV/g) sensors
operate reliably over wide amplitude and frequency ranges
under adverse environmental conditions.
They are structured with permanently polarized compres-
sion-mode quartz elements and a microelectronic amplifier
housed in a lightweight metal case. Three different case and
connector configurations give you a choice in mounting and
cabling. The built-in electronics operate over a coaxial or two-
conductor cable; one lead conducts both signal and power.
Solder terminal versions are normally supplied with a ribbon
wire cable (10ft. long; Model007B10) attached. Model 303A02
• quires Model 002G coaxial cable with a Micro 5-44connector
on one end.
Test results of the behavior of the Model 303Aare presented
below. Note especially the sharp clean signals free of cable noise
and the exceptionally high frequency response. Because of the
low mass. Series 303A sensors measure motion of many light
structures without appreciably changing the structure or behav-
ior of the test object during the measuring transaction.
