FOS-series fibre optic sensors are designed to be reliable and work for a wide range of applications. Fibre optic temperature measurement using the FOS-series sensors provides accurate ±0.8°C readings combined with a fast response time up to 200ms. The FOS-Series boasts a -200°C to 250°C temperature measurement range as well as 1.6mm (1/16") probe diameter. One of the greatest aspects of fibre optic temperature sensing is that the sensors do not require any recalibration. Fibre optic sensors have high repeatability, stability and no signal degradation due to cable length. Fibre optic sensors transfer information to the fibre optic monitor via light that travels through the fibre optic cable. This is quite different compared to traditional sensors that use resistance/voltage to communicate with monitors. Since fibre optic sensors use light the signal is very fast, reliable and is not influenced by outside forces such as EMI, RFI, NMR or microwave radiation.
