Use the above graph to determine the temperature class for a given fluid and ambient temperature. The maximum surface

temperature for dust is as follows: T6:T 80 °C, T5:T 95 °C, T4:T 130 °C, T3:T 195 °C, T2 to T1:T 254 °C. The minimum ambient and

process fluid temperature allowed for dust is –40 °C.

The use of the sensor at an ambient temperature higher than +55 °C is possible, provided that the ambient temperature does not

exceed the maximum temperature of the medium taking into account the temperature classification and the maximum operating

temperature of the sensor.

Ambient temperature range Ta –240 °C to +55 °C

The use of the sensor at an ambient temperature higher than +55 °C is possible, provided that the ambient temperature does not

exceed the maximum temperature of the medium taking into account the temperature classification and the maximum operating

temperature of the sensor.
