Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o C, o F, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.
The acceleration sensor houses three small thin silicon accelerometers, each
accelerometer is oriented along a different axis (X, Y, or Z). When an accelerometer
experiences an acceleration along it
’s axis the silicon will flex to a very specific angle
proportional to the acceleration it is experiencing. Each accelerometer is connected to
a capacitor and as the silicon flexes the capacitance changes which in turn changes
voltage flowing through the system. Acceleration and voltage have a linear
relationship which allows the acceleration to be calculated easily using the voltage
reading.
Maintenance and storage:
 Never submerge the NeuLog plastic body in any liquid.
 Do not allow liquid into the acceleration sensor’s body.
 After use, gently wipe away any foreign material from the acceleration
sensor.
 Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship for a
period of 3 years from the date of purchase. Our warranty does not cover damage of
the product caused by improper use, abuse, or incorrect storage. Sensors with a shelf
life such as ion selective proves have a warranty of 1 year. Should you need to act
upon the warranty please contact your distributor. Your sensor will be repaired or
replaced.
