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 at any time using software.
The pressure sensor uses the
effect. The transducer is based
on silicon between metal foils that changes its resistance according to
pressure. One side of it is at complete vacuum that enables to measure the
absolute pressure on its other side.
This transducer is built as a strain gauge with Wheatstone bridge circuit so
its output is a voltage depends on it absolute pressure.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid
Do not allow liquid into the NeuLog plastic body.
After using the probe, wipe off all excess material, liquid or residue
from the sensor.
Store in a box at room temperature out of direct sunlight.
