Technical Facts To get 100 Ohms of
platinum wire inside TDI detectors means starting with a wire
length of 250mm (10") the diameter of the wire if finer than
that of a human hair.
The Alpha value of the wire has
a tolerance of just +/- 3 parts per million. For the detector
to reach DIN standard B the equivalent tolerance in length is
equal to just 0.25mm (0.01").
A staggering 70% of
TDI's detectors are to 1/5th of this tolerance, just 0.05mm
TDI leads the
world in being able to produce in quantity to these
TDI's production and checking
tables have measuring performance similar to that used in a
high quality secondary calibration laboratory.
TDI's are hand made from beginning to end.
Since the start in 1983 TDI has produced
more than 6 million detectors.
find their way into space, have been used on Concorde, Formula
One racing cars, nuclear submarines...
Applications are diverse from food testing, the brewing
industry, textile production, pharmaceutical applications in
fact every corner of science and industry.
When there is an application for high
accuracy, high stability temperature measurement TDI detectors
can be found.
TDI detectors are used in the worlds best Industrial Platinum Resistance Thermometers.
