SENSORS
suitable for most IEPE accelerometers and
remote charge converters.
The 35C offers many benefits to
aerospace engineers whose end goal is
keeping people safe and the planet green.
Its technology requires little operator
attention, training or installation
expertise. High quality data is effortlessly
acquired over extended distances with
minimal noise and electrical interference.
You could even heat up your coffee to
125°C, pour it over the 35C and still get
good data without harming the device.\\

same cable that supplies the required
constant current power.
Typical resonance frequency of the
Model 35C is 40 kHz with maximum
amplitude response (±5%) of z and y axis of
2-8000 Hz and maximum amplitude
response (±5%) of x axis of 2-6000 Hz.
Highest nominal range is ±2800 g’s.
The 35C also offers an intrinsic self-test
feature. If the bias voltage is lower than
the specified range, users should suspect a
short-circuit or negative overload. Should
the bias voltage be higher than specified
range, then one is likely to find a positive
overload, broken cable or a cable not
connected problem.
Further, this accelerometer operates
directly with industry standard, easily
available data systems that have built-in
constant current input that result in low
per channel costs. Endevco also offers
optional Models 123 and 133 signal
conditioners for the 35C.
For those who wish to create a custom
current source for their system, a circuit
can easily be constructed. This circuit uses
a readily available LM317T IC and the
resistors and capacitor are available from
most electronic parts distributors. The
input voltage should be at least 30 volts and
should come from a clean, regulated power
supply. This circuit provides 4mA which is
