Endress+Hauser 31
Operating conditions: Process
Process temperature range
The maximum permitted temperature at the process connection is determined by the O-ring version ordered:
Device O-ring material Process temperature
FMP56 FKM (Viton GLT) –30 to +120 °C (–22 to +248 °F)
EPDM –40 to +120 °C (–40 to +248 °F)
FMP57 FKM (Viton GLT) –30 to +150 °C (–22 to +302 °F)
EPDM –40 to +120 °C (–40 to +248 °F)
The medium temperature can be higher.
However, when using rope probes the stability of the probe rope is reduced by structural changes at
temperatures over 350 °C (662 °F).
Process pressure limits
Device
Process pressure
FMP56, FMP57 –1 to 16 bar (–14.5 to 232 psi)
This range may be reduced by the selected process connection. The pressure rating (PN) specified on the
flanges refers to a reference temperature of 20 °C, for ASME flanges 100 °F. BPay attention to pressure-
temperature dependencies.
Please refer to the following standards for the pressure values permitted for higher temperatures:
• EN 1092-1: 2001 Tab. 18
With regard to their temperature stability properties, the materials 1.4435 and 1.4404 are grouped
under 13E0 in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.
• ASME B 16.5a - 1998 Tab. 2-2.2 F316
• ASME B 16.5a - 1998 Tab. 2.3.8 N10276
• JIS B 2220
Materials in contact with
process
• Endress+Hauser supplies DIN/EN flanges and threaded process connections made of stainless steel
according to AISI 316L (DIN/EN material number 1.4404 or 1.4435). With regard to their temperature
stability properties, the materials 1.4404 and 1.4435 are grouped under 13E0 in EN 1092-1 Tab. 18.
The chemical composition of the two materials can be identical.
