The FOS-Series fiber optic sensors are designed to be reliable and work for a wide range of applications. Fiber optic temperature measurement using the FOS-Series sensors provides accurate ±0.8°C readings combined with a fast response time up to 200 ms. The FOS-Series boasts a -200°C to 250°C temperature measurement range as well as 1.6 mm (1/16") probe diameter.

One of the greatest aspects of fiber optic temperature sensing is that the sensors do not require any recalibration. Fiber optic sensors have high repeatability, stability and no signal degradation due to probe length.

The FOS-Series paried with the FOM-Series fiber optic monitors, temperature measurements can be monitored and datalogged to an Micro SD external memory card and sent to third party datalogger/system through RS-485 output or 0-10 V / 4-20 mA analog outputs.

These devices are used for various applictions and environments. Common applications include transformer factories, chemical processing, medical equipment testing (MRI, PETSCAN, NMR), commercial grade microwave heating, food and beverage processing, electric vehicle and battery testing and wood drying.

Fiber optic sensors transfer information to the fiber optic monitor via light that travels through the fiber optic cable. This is quite different compared to traditional sensors that use resistance/voltage to communicate with monitors. Since fiber 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.

Is the FOS-LT-2 compatible with the Omega FOB-104 Meter which used the FOBS-2 probes.

Asked by: Jaime
Hi Jaime Thank you for the inquiry. Yes, the FOS series are compatible with the FOB-104. Best regards OMEGA

Hi, I was wondering if you are able to provide FOS that measure high temperatures like 700 C with multi sensing point in the same probe.

what is the max sensing distant from tip of sensor to object

Asked by: john foo
All sensor tips must be in contact with what is being measured to work correctly.
