PPT80 Low Pressure High Temperature The PPT80 is a pressure transducer (.875" diameter) manufactured for a high operating temperature range for challenging applications. Constructed from components selected to operate reliably at elevated temperatures, the HI2200 has a stainless steel and titanium housing. A novel temperature-independent gas pressure sensor based on a reflective fiber Lyot filter is presented in this paper. The pressure sensitivity of the FP gas pressure sensor is 4.28 nm/MPa with a high linear pressure response over the range of 0.1-0.7 MPa, and the temperature sensitivity is 14.8 pm/°C under the range of 20-800 °C. At each temperature test point, the corresponding interference spectrum was recorded. Yet, even in these difficult high temperatures, they provide outstanding accuracy, long-term calibration stability and reliability. Moreover, benefitting from the ultra-low thermal expansion coefficient of HB-PCF, the HB-PCF-based reflective Lyot filter overcomes the temperature cross-sensitivity faced by conventional birefringence fibers-based fiber sensors.
