Temperature Class and surface temperature

Fieldhousing ME21: The maximum temperature of the fieldhousing by an ambient temperature of -40…+60°C is less than +80°C, so the Temperature Class of the fieldhousing is T6. The surface temperature is T115°C.

Primary MC2_compact and ME2_remote_: The maximum temperature of the primaries by an ambient temperature of -40 …+60°C for Zone1 / DIV1 and Zone2 / DIV2 are shown in following table.

. The surface temperature for Zone1 / DIV1 is depending on the fluid temperature.

T surface = T 115°C.... T(fluid) Model MC2_ T surface = T 115°C Model ME2_ (limited by temperature fuse on power supply board)

This is also valid for insulated tubes or tubes with external heatings even if the heating temperature is ≤ fluid temperature.

The thermal insulation of the tube and the flowmeter can be made if necessary by the customer. The insulation may take place up to the 100mm around the primary housing. The technical data are not changed thereby.

Primary MS2_: The maximum temperature of the primaries by an ambient temperature of -20 …+50°C for Zone1 / DIV1 and Zone2 / DIV2 is shown in following tables. Zone 1/ DIV1: The over-temperature of PT-1000 on meter single-tube is ≤ 70°C. That has an influence on the temperature classes. Acc. IEC60079-11 it is possible to increase the maximum surface temperature for small components. With this possibility the correlation between ambient-, fluid temperature and temperature class against the existing UL-approval is given to: T6: = left, because: the over-temperature is higher than the existing UL-Approval T5: = unchanged 80°C, because:

at T5 for small components <10cm² the maximum surface temperature could be 150°C. So 150°C maximum – 70°C over-temperature PT1000= 80°C fluid.

T4: = 125°C, because:

at T4 for small components <10cm² the maximum surface temperature could be 200°C. Because of T4 maximum temperature is 135°C we decided 125°C (10°C buffer) for the fluid. This is with less influence of small components.

T3: = 180°C, because:

There is no logical reason why it should be possible to install the flowmeter in T4 areas but not in T3, even if IEC60079-11 does not note something about small components for T3. So we use the same maximum as in the existing UL-Approval.
