4、OMEGA

Whether used for communications or infrared temperature measurement, fiber optics offer some inherent advantages for measurements in industrial and/or harsh environments:
– Unaffected by electromagnetic interference (EMI) from large motors, transformers, welders and the like;
– Unaffected by radio frequency interference (RFI) from wireless communications and lightning activity;
– Can be positioned in hard-to-reach or view places;
– Can be focused to measure small or precise locations;
– Does not or will not carry electrical current (ideal for explosive hazard locations);
– Fiber cables can be run in existing conduit, cable trays or be strapped onto beams, pipes or conduit (easily installed for expansions or retrofits);
– Certain cables can handle ambient temperatures to over 300°C–higher with air or water purging.

9、VOLO

 

FISO’s Fiber Optic Temperature Sensors provide accurate, stable, and repeatable measurements. These measurements are based on variations of the reflected light — when compared to the emitted light — due to thermal expansion of the highly stable glass used within the sensor. The fiber optic lead cable can be up to several meters long without affecting the quality or the accuracy of the results.

10、OSENSA

Fiber optic temperature sensors are solutions consisting of one or more fiber optic probes attached to a temperature transmitter (also known as signal conditioner) electronic device. OSENSA developed multi-channel fiber optic temperature sensors that are targeted for applications such as electrical power transmission and distribution. Unlike previous generation fiber optic signal conditioners which were bulky and expensive lab devices, OSENSA’s fiber optic temperature transmitters are in similar form factor and are mounted like a thermocouple or RTD (Resistance Temperature Detector) transmitter. They are DIN rail mountable and include standard 4-20mA analog outputs as well as an industrial RS-485 serial bus for modbus communication to daisy-chained devices. OSENSA’s fiber optic probes also share a similar look and feel as standard thermocouples and RTD’s. Best of all, the cost of OSENSA’s fiber optic temperature sensors is close to commercial RTD and transmitter combinations.
