Produktübersicht: 5616 | Sekundäres Referenz-PRT
The 5616's temperature range is -200°C to 420°C. Its high-purity platinum element and ruggedness make it particularly suitable for calibration in the lab or in the field. When selecting a reference with a platinum element, two things are important to consider: short-term reproducibility and long-term drift. When PRTs thermally cycle through their temperature range, as they do during calibration, their resistance at the triple point of water can move up or down in an unexpected range. Fluke Calibration defines this range (called "short-term reproducibility") as the reproducibility at the triple point of water during thermal cycling. The 5616 PRTs are among the best performing in their class, with short-term reproducibility of better than ± 0.010°C (± 0.004°C is normal). In addition, the drift of the 5616 is ± 0.007 °C at the triple point of water and maximum temperature (420 °C) for 100 hours. These specifications are for k=2 and therefore have a 95% confidence level.
The 5616's sealed INCONEL® 600 shaft is 11.75" long and 1/4" diameter. The PTFE-sheathed cable is silver-plated copper terminated with four-wire leads to eliminate lead wire resistance from affecting measurements. Use the 5616 with the 1523/1524 1523 Portable Reference Thermometer , 1524 Portable Reference Thermometer , the 1560 Black Stack , the 1529 Chub-E4 , or the Tweener thermometers with digital displays.
Each sensor is supplied with a manufacturer's calibration report. The report includes expanded uncertainty (k=2) at seven calibration temperature points, ITS-90 calibration coefficients, and a temperature versus resistance table in 1°C increments. Compare the 5616 to other secondary reference PRTs. You'll love the price, but it's the performance that will really win you over.
