| Fiberoptic temperature sensors of different manufacturers use opitcal fiber ends usually treated with special high complexity. These fiber ends provide for example miniature Fabry-Perrot-Cavities, GaAs chips or Bragg gratings inside the fiber.
All these variants have a very complex expenditure in manufacturing and they are mechanical sensitive in use. There’s an end of it!
Fiberoptic temperature sensors of getSens.com are now available as nano-powder-version. Nano-scaled GaAs powder adhered to glue substitudes the previous GaAs chip. Due to light scattering of the particles the optical response is similar to the one of the crystal.
SEM figure: tip of the Nano-probe
Advantage:
- better rugged sensors
- no fall off for GaAs-Chip
- repair of probe by customer possible
- diameter of sensor tip 0,5mm
All one channel and multi-channel cascaded measuring instruments of the getTemp series are available by now with our Nano probes TS-Nano.
Further properties:
- probe length max. 2m
- response time compared with standard probes (TK2) a little bit longer, approx. 2s
- temperature range up to 200°C
