7) Through their small design, face-sensitive measuring resistors serve to reduce the heat dissipation with short insertion
lengths. Available for the temperature range up to 150 °C (302 °F).
For thermowell insertion lengths of less than 50 mm, face-sensitive measuring resistors are recommended.
For thermowell insertion lengths of less than 11 mm, face-sensitive measuring resistors are generally used.
8) Class accuracy AA (1/3 DIN) only valid in the temperature range 0 ...150 °C (32 ... 302 °F)
Class accuracy A only valid in the temperature range -30 ...+150 °C (-22 ... +302 °F) or -30 ...+250 °C (-22 ... +482 °F),
otherwise class B
9) The stated ingress protection only applies when plugged in using mating connectors that have the appropriate ingress
protection.
