Bending Radius	Sheath may be ordered with a bend on a minimum radius of 19 mm (3/4 in) except for 50 mm (2 in) area of sheath near tip. (Hart lab requires 20 cm [8 in] of unbent sheath to re-calibrate.)
Calibration	Includes manufacturer’s NVLAP-accredited (lab code 200706-0) calibration and table with R vs. T values in 1 °C increments from –196 °C to 500 °C (to 300 °C for 5627A-6 and 5627A-9). ITS-90 coefficients included.
Immersion	At least 100 mm (4 in) recommended
Calibrated Accuracy† (k=2)	± 0.026 °C at –196 °C ± 0.046 °C at 0 °C ± 0.077 °C at 200 °C ± 0.124 °C at 420 °C
Size	5627A-12: 305 mm x 6.35 mm (12 in x 1/4 in) 5627A-9: 229 mm x 4.7 mm (9 in x 3/16 in) 5627A-6: 152 mm x 4.7 mm (6 in x 3/16 in)
†Includes calibration uncertainty and 100 hr drift.

When buying a PRT, performance isn’t the only criterion you need to look at. The real issues are price-to-accuracy and price-to-durability ratios. 

5627A probes have a temperature range up to 420 °C and an accuracy as good as ± 0.025 °C. They come in three different lengths. (Both six- and nine-inch models cover –200 °C to 300 °C.) 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 5627A is 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 19 mm (3/4-inch) for flexibility and durability. (Bend, if any, should be specified at time of order.) 

Six- and nine-inch 5627As are calibrated at –196 °C, –38 °C, 0 °C, 200 °C, and 300 °C. For 12-inch versions the point at 300 °C is replaced by a calibration point at 420 °C. 

Each probe is individually calibrated and includes a NVLAP-accredited report of calibration from the manufacturer, lab code 200706-0. 

This probe is an excellent value. It has the price-to-accuracy and price-to-durability ratios you should demand in every  PRT you buy!
