Introduction
DT-01-ATX was originally designed for prototyping
of LICHTZEN AE / AITNIX heat flux sensors. The design is made to be sensitive and easy to
handle.
DT-01-ATX can be used both to construct heat flux
sensors as well as differential temperature sensors. The materials used in the
DT-01-ATX thermopile are copper and copper-nickel (CuNi) alloy. The copper part
however is actually consisting of copper plated CuNi. Because the copper
conductivity dominates, the copper plated CuNi practically behaves like copper.
The total sensor is extremely stable.
Typical applications of DT-01-ATX are prototyping
of calorimeters and thermal conductivity measurement equipment. The ribbon can
either be spread out across a surface or be rolled up to create a small
sensitive area. A typical way of installing is by laying DT-01-ATX into a groove, and
using a plastic casting material to fill up the space to create a solid
sensor.
For readout one only needs an accurate
voltmeter that works in the millivolt range. To convert the measured voltage to
a heat flux or differential temperature, the voltage must be divided by the
calibration constant. This constant can only be determined once the sensor is
built-in. Please consult LICHTZEN AE / AITNIX for further engineering
considerations.
Suggested use
Prototyping of heat flux sensors,
calorimeters, flow meters, radiation sensors, thermal conductivity sensors,
laser power meters, flow sensors etc.
