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 (for
o
o
example:
C,
F, Lux, %, ppm).
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 ultrasonic transducer is a device which converts a
pulse train to transmitted ultrasonic pulses that can be
sensed and converted back to an electronic pulse train
by another similar ultrasonic transducer or by itself.
The ultrasonic transducer is based on ceramic crystal,
which is cut in a certain way and is placed between two
metal plates.
The crystal is characterized by the piezoelectric effect.
Electrical field changes between the plates create
mechanical vibrations in the crystal.
The crystal has a resonance frequency. The mechanical
vibrations and electrical reactions depend on this
resonance frequency.
