Advantage:
Ultra thin: the local temperature increase across
the sensor thermal resistance is minimized, and the
period of time needed to reach the steady state of heat
flow inside the sensor is minimized.
No dependent temperature: the greatest advantage of
the Captec sensor is to have a sensitivity which no
dependent temperature between the range extending from
- 200°C to +200°C.
Flexibility: Size and shape on request, custom
made for all type of special application, option thermocouple,
water proof available.
Measurement: Short response time, high sensitivity
(can be customized), low electrical resistance. |
Applications:
|
- measure the difference of radiant flux in the two
sides of a product in an environment.
- process control, test of environment.
