1 The permitted ambient temperature at the separate housing is the same as indicated for the compact housing.
Influence of process temperature
Error in case of fully insulated probes typically 0.13 %/K related to the full-scale value.
12.6.2 Process pressure limits
Probe ⌀10 mm (0.39 in) including insulation
–1 to 25 bar (–14.5 to 362.5 psi)
Probe ⌀16 mm (0.63 in) including insulation
• –1 to 100 bar (–14.5 to 1 450 psi)
• in regards to an inactive length, the maximum permitted process pressure is
63 bar (913.5 psi)
• for CRN approval and inactive length: the maximum permitted process pressure is
32 bar (464 psi)
Probe ⌀22 mm (0.87 in) including insulation
–1 to 50 bar (–14.5 to 725 psi)
Refer to the following standards for the pressure values permitted at higher temperatures:
• EN 1092-1: 2005 Table, Appendix G2
With regard to its resistance and temperature property, the material 1.4435 is identical
to 1.4404 (AISI 316L) which is 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
The lowest value from the derating curves of the device and the selected flange applies.
