How to Use the 34203A
➤
Connect a +8 to +30V DC power source to pins 8 and
9.
➤ Connect a differential or floating input A/D converter
to each signal and signal common pins (pins 1 and 2
for Accelerometer 1,pins 3 and 2 for Accelerometer 2,
pins 5 and 2 for Accelerometer 3, and pins 5 and 2 for
Temperature). For best results use a converter with an
input impedance greater than 1MΩ and common
mode rejection ratio greater than 60dB.Single-ended
converters are not recommended but if used, leave
pin 2 unconnected to eliminate ground loops. A
positive acceleration (labeled on the accelerometer
cover) causes a positive change on the
corresponding output.
➤ Keep cable lengths between the accelerometer and
A/D converter as short as practical. Use shielded
twisted pair wiring, especially near electric motors or
other noise sources.
➤ As a rule of thumb, sample frequency should be at
least 10 times the signal bandwidth when linear
interpolation is used for signal reconstruction.Built-in or
external low-pass filtering can be used to lower the
n o i s e fl o o r a n d e l i m i n a t e s p u r i o u s p e a k
measurements from short-duration shock impulses
with insignificant energy content.
* Scale linearly with range option Rnnn.
➤
Use two 3,0 x 0,5 mm thread machine screws to attach
to one of the three 34203A mounting faces. DO NOT
thread a screw more than 2.5 mm (0.100 inch or 5
turns) into any 34203A mounting face as this can
damage the accelerometer and will VOID the
warranty.
➤ A light film of oil or silicone grease can be used to
enhance contact between the mount and the
34203A.
