FPI-HR High Resolution Fiber Optic Signal Conditioner
General Temperature and Pressure Applications
This "signal conditioning" module is both the light source and receiver of the fiber optic measurement system. The FPI-HR or FPI-HS convert the optical signal to a pressure reading and requires no external amplification box. The researcher may plug the catheter’s optical connector directly into the module or may use an (optional) extension cable with accompanying connection box.
FPI-HR:
Single channel (250Hz)
Dual channel (125Hz)

1. Time required to reach 63% of a temperature step.
2. Includes reproducibility (sensor/module exchange), repeatability and hysteresis, non-linearity, scale error, offset error, conditioner temperature compensation error.
Temperature:
Accuracy of ±0.25°C can be achieved using the 25°C to 45°C calibration.
Accuracy of ±0.40°C can be achieved using the -10°C to 120°C calibration.
Pressure:
Accuracy at room temperature.
3. SCAI is an SCA connector with smart chip communicating calibration data to signal conditioner module.
