-80 to 300°C Fiber Optic Monitors

The FOM-Series fiber optic monitors are designed to be compact and reliable. Fiber optic temperature measurement using the FOM-Series monitors provides accurate readings combined with a user friendly interface. The FOM-Series boasts a -80°C to +300°C temperature measurement range as well as ±1.0°C (+/- 0.2°C in relative temperature) accuracy.

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/lead length. The temperature measurement data can be 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 applications 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.
