Standard Platinum Resistance Thermometer(BB 660/25.5)
BB 660/25.5 is the Standard Platinum Resistance Thermometer jointly developed with National Institute of Advanced Industrial Science and Technology (AIST/NMIJ) as an interpolation device for measurements from -190℃ to approximately +660℃. Employing a sensing element with a single helix coil structure (Japan Pat. No.3380523) provides superior stability at high temperature and high resistance to vibration. It can also provide smaller self-heating temperature rise and high response.
Standard SpecificationsCharacteristics
Sensing Element:Single helix coil wound in a quarts sensing frame at noninductive winding (L ≦ 40mm)
Sensing Element:Platinum (4-wires connection)
Quartz Sheath:φ7mm x approx.570mm length
Sensing Handle:φ19mm x approx.100mm, Aluminum outer casing
Lead Wires:4 Teflon insulated copper wires jacketed with cross-linked polyethylene x 2.5m
Temperature Range:from -189.3442℃(Ar TP) to +660.323℃(Al FP)
Resistance Value:approx. 25.5Ω R0
Resistance Ratio:WGA (29.7646℃)≧1.11807
Reproducibility:within 1mK
