The standard FOTEMP1-OEM-MNT controller features include a calibrated measurement range of -40°C to +300°C and built-in USB, RS232 and SPI interfaces. It operates in conjunction with all TS Series GaAs Fiber Optic Temperature Sensors to provide a discrete temperature monitoring solution that can operate accurately and reliably in challenging environments such as mines where electronics-based temperature sensors (thermocouples, RTDs) cannot function.
Micronor said the fibre optic sensor’s non-metallic, passive optical design provides immunity to electromagnetic interference (EMI), radio frequency interference (RFI), microwaves, high voltage, extreme magnetic fields, radiation, chemicals, and explosive atmospheres. In these environments, GaAs fiber optic temperature sensors enable new and unprecedented solutions impossible for electronic sensors.
Typical applications include monitoring temperature inside high voltage transformers and switchgears. The use of low-loss optical fibre allows interference-free, remote temperature monitoring up to 2,000m.
