6) 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.
7) Class accuracy AA only valid in the temperature range 0 ...150 °C (32 ... 302 °F)
8) The stated ingress protections only apply when plugged in using line connectors that have the appropriate ingress
protection.
9) Not tested at UL
