using a proprietary alignment method that
incorporates continual on-line spectral monitoring.
The structure is further processed to
greatly enhance the spectral characteristics of the
sensor before encapsulation within the material of
interest or as a stand-alone optical sensor.
Temperature sensors can be manufacturing using this
sensing element with the addition of pressure screening.
When designed as a temperature sensor
these devices have extremely small thermal mass and can
response to small transient changes in temperature
otherwise unseen by standard thermocouple, thermistor or
NTC probes. Tests results detailed in the graph below
show the temperature response of a pressure isolated
sensor embedded in a silicone capsule. The thermal
response id due to material heat and cooling when
subjected to compression and expansion loads
