*self heating T[mK] measured for Pt100 at 1mA measurement current at 0C
L: Chip length (sensor length without connections)
T: Chip thickness (sensor thickness without connections)
W: Sensor width
H: Sensor height (incl. connections and strain relief)
Notification: The values in the table are of informative nature only. Due to different measurement conditions you
might assess deviant self heating and response time values of your application.
Tolerances of dimensions
Sensor width (W) ± 0.2 mm
Wire length ± 1.0 mm
Sensor length (L) ± 0.2 mm
Tube length ± 0.2 mm
Sensor height (H) ± 0.3 mm
Tube diameter ± 0.1 mm
Sensor thickness (T) ± 0.1 mm
