Model CMF400 with core processor

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: T5:T 95°C, T4:T 130°C, T3:T 195°C, T2 to T1:T 234°C.

Ambient temperature range Ta –40 °C to +60 °C

High-temperature models CMF200A, CMF200B, CMF300A, CMF300B, CMF400A, or CMF400B with

core processor or Model 1700/2700 transmitter

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: T5:T 95 °C, T4:T 130 °C, T3:T 195 °C, T2: T 290 °C, T1:T 363 °C. The minimum ambient and

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

Since the electronics are mounted approx. 1 meter away from the sensor by means of a flexible stainless steel hose, 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.
