Process temperature range
for devices with ceramic
process isolating diaphragm
FMD71
• Thread and flanges: –25 to +125 °C (–13 to +257 °F)
• Hygienic connections:–25 to +130 °C (–13 to +266 °F) , 150 °C (302 °F) for max. 60 minutes
• High-temperature version: –15 to +150 °C (+5 to +302 °F); see ordering information, order code
610, option "NB".
• For saturated steam applications, use a device with a metal process isolating diaphragm, or
provide a siphon for temperature isolation when installing.
• Pay attention to the process temperature range of the seal. See also the following table.

The process temperature ranges indicated here refer to the permanent operation of the FMD71. For devices with hygienic process connections, a
higher temperature (max. 150 °C (302 °F)) may be applied for a short period (max. 60 min.) for cleaning purposes. 60 min.) eine höhere Temperatur

4) These seals are used for devices with 3A-approved process connections.
Applications with changes in temperature
Frequent extreme changes in temperatures can temporarily cause measuring errors. Temperature
compensation takes place after a few minutes. Internal temperature compensation is faster the
smaller the change in temperature and the longer the time interval.
