The principals of operation for this instrument are the latest in science
and technology. Custom-developed Peltier Cells are arranged on the back
and sides of the bath vessel. Newly designed high density air heat
sinks on the outer surfaces (hot side) of these Peltier Cells are cooled by
muffin fans running at half of their rated voltage. The bath liquid (2.5
liters) is constantly circulated by recycled bath vapors to ensure uniform
temperature distribution and stability. The temperature is controlled (both
heating and cooling) with a custom designed 16 bit digital pulse width
modulator running at a very high frequency.
The TE-3000 can be calibrated to any temperature reference standard for
any desired Celsius or Fahrenheit temperature. The controls for entering
the target (desired) temperature and the calibration at this temperature are
very simple and straight forward. The instrument remembers these
calibration corrections for every possible temperature as well as the latest
desired temperature so that upon power-up, the bath will
adjust to these last known and entered parameters.
The TE-3000 was designed for the future with built in capability for
remote control and networking with a new family of instruments. With
this remote interface capability, it is now possible to obtain quality
assurance data via a computer network. The TE-3000 was also designed
to ensure that its capabilities may be easily changed or updated with new
operating firmware via a remote download over this same network.
