FMPI — 300 – 2000°C
Expert system multi-wavelength pyrometer with on-line tolerance and signal strength display, spectral and total emissivity correction, and absorption/emission compensation. Measurement is either continuous or on operator demand. Results are displayed on screen and logged in non-volatile memory. Thermal spectrum is displayed on screen, and can be saved to non-volatile memory for later analysis. Instrument consists of optical input (sensor), fiberoptic interconnection cable, and console. Console includes Intel/Windows PC. Data analysis during first 30 days of operation is included.
| Temperature range: | 300 – 2000°C or 573 – 3632°F |
| Accuracy: | ± 0.15% on grey targets (measured between 500 and 2000°C) ± 0.25 – 0.75% on non-grey targets (typical) |
| Tolerance: | On-line tolerance in °C or °F; tolerance reported is the real-time accuracy of the individual measurement displayed |
| Signal strength: | Relates the measured intensity at a mid-range wavelength to the expected intensity for an ideal target at the same temperature. Signal strength is the emissivity at that wavelength if field of view is filled, no atmospheric absorption is present, and optics are clean. |
| Interference: | Automatic compensation for atmospheric absorptions or emissions from combustion products or process offgas |
| Reproducibility: | ± 1°C |
| Resolution: | 0.1°C or °F |
| Wavelength range: | 900 – 1700 nanometers |
| Wavelength resolution: | 2 nanometers |
| Number of wavelengths: | 250 |
| Data acquisition time: | 10 microseconds minimum |
| Analog output (optional): | 0 – 20, 4 – 20 mA, 0 – 10 VDC |
