Optical pressure sensors offer an alternative method to collect high-quality pressure measurements within harsh environments that are not suitable for electrical equivalents. The Fibos UHT-PT series can collect dynamic and static pressure measurements with a ±0.25% FSO measurement uncertainty if environmental temperature is static. The UHT-PT body temperature can operate up to 400°C, with inlet gas temperatures at the diaphragm reaching up to 1,000°C. Temperature compensation is performed by means of a thermocouple or a second optical sensor within the transducer. Mounting method, material substitutions, custom dimensions, and alternative cable lengths can be provided upon request.

Fibos optical pressure transducers meet PiMS™ (Pi-FBG Measurement Standard). To achieve the performance specifications presented, a signal conditioner that utilizes the PiMS™ technique is required.
