The smallest input signal that will cause a readable change in the
output signal.
Time constant
The time it takes for the output change to reach 63% of its final
value.
Toughness
A measure of the amount of energy absorbed by a material as it
fractures, indicated by the total area under the material's
tensile stress-strain curve.
Transduction (self-generating or modulating)
The conversion of the signal to be measured into another, more
easily accessible form. Source of energy for transmission of the
sensor signal.
Transduction mode (direct or indirect)
How the sensor acquires the desired information from the
material. In general, this parameter is an indication of the
ability of the sensor signal to provide information regarding a
material property or state of interest.
Transformer
Device using magnetically linked inductors to change AC voltage
level.
Transient response
The response of the sensor to a step change in the measurand.
Transistor
Semiconductor device used for amplification and switching.
Transmission
Refers to system for carrying electric power at voltages above
100,000 volts.
Transmission electron microscope (TEM)
A microscope that produces an image by using electron beams to
transmit (pass through) the specimen, making examination of
internal features at high magnifications possible.
