WZP PT100 thermal resistance, temperature sensor
Diameter 3.98mm-Long 29.85mm
Lead length 50Cm
WZP series of platinum thermal resistance components
Platinum thermal resistance is an accurate, sensitive and stable temperature sensor. Platinum thermal resistance element is made of micro-ceramic tube, the hole inside the system made of platinum thermal resistance wire twisted coil made of temperature sensing element, the temperature sensor can be done quite small (the smallest diameter can be Ф1.6 ~ Ф0. 3mm) so it can be made into a variety of miniature temperature sensor probes. Can be used in the range of -200 ~ + 420 ℃ temperature.
Note: ① A-level tolerance is not applicable in the range of t> 650 ℃ temperature range, and not suitable for use of two-wire system.
2. Self-heat impact
Platinum resistance allows the maximum measured current through 5mA, the resulting temperature rise is not greater than 0.3 ℃
3. Thermal resistance temperature sensing element at 0 ℃ when the resistance value (R0) and it at 100 ℃ Resistance (R100) Ratio (R100 / R0)
Indexing number Pt100: Class A R0 = 100 ± 0.06 Ω
Class B R0 = 100 ± 0.12 Ω
W100 = R (100 ° C) / R (0 ° C) = 1.3851
