When buying an RTD, performance isn’t the only criterion you need to look at. The issue really is price-to-accuracy and price-to-durability ratios. The Model 5627 probes have a temperature range up to 420°C and an accuracy as good as ±0.05°C. They come in three different lengths. Each instrument is shipped with its ITS-90 coefficients and a calibration table in 1°C increments. One of the best features of this sensor is that it conforms to the standard 385 curve, letting you use your DIN/IEC RTD meters fully. Why use a probe that’s less accurate than your meter? The Model 5627s are manufactured using a coil suspension element design for increased shock and vibration resistance. It has a mineral-insulated sheath with a minimum bend radius of 3/4-inch for flexibility and durability. (Bend, if any, should be specified at time of order.) Six-inch 5627s are calibrated at –196°C, –38°C, 0°C, 200°C, and 300°C. For 9-inch and 12-inch versions, an additional point is added at 420°C. Each probe is individually calibrated and includes a report of calibration from the manufacturer. Contact Hart for calibration in Hart's NVLAP accredited lab. This probe is an excellent value. It has the price-to-accuracy and price-to-durability ratios you should demand in every RTD you buy!
