15.4.2 Thermal shock
≤ 120 K/s
15.4.3 Process pressure range
L
WARNING
The maximum pressure for the device depends on the lowest-rated element, with
regard to pressure, of the selected component. This means that it is necessary to pay
attention to the process connection as well as the sensor.
‣
For pressure specifications, see the "Mechanical construction" section.
‣
Only operate the device within the specified limits!
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the device.
The following data apply over the entire temperature range. Pay attention to exceptions
for flange process connections!
• ECTFE, PFA: –1 to 40 bar (–14.5 to 580 psi)
• Enamel: max. –1 to 25 bar (–14.5 to 363 psi)
Refer to the following standards for the permitted pressure values of the flanges at higher
temperatures:
• pR EN 1092-1: With regard to its stability-temperature property, the material 1.4435 is
identical to 1.4404, which is classed as 13E0 in EN 1092-1 Tab. 18. The chemical
composition of the two materials can be identical.
• ASME B 16.5
• JIS B 2220
In each case, the lowest value from the derating curves of the device and the selected
flange applies.
Canadian CRN approval: more details about the maximum pressure values are available in
the download area of the product page under " www.endress.com" .
15.4.4 Test pressure
Test pressure = 1.5 · PN
• ECTFE, PFA: PN = 40 bar (580 psi)
Enamel: PN = 25 bar (362.5 psi)
• Membrane burst pressure at 200 bar (2 900 psi)
The device function is limited during the pressure test.
The mechanical integrity is guaranteed at pressures up to 1.5 times the process nominal
pressure PN.

Setting > 0.7 g/cm 3 (as-delivered state)
Liquids with density 0.5 to 0.8 g/cm 3
Setting > 0.5 g/cm 3 (can be ordered as preset value or user-configurable)
Liquids with density > 0.4 g/cm 3 (not for devices with SIL approval)
Setting > 0.4 g/cm 3 (can be ordered as preset value or user-configurable)
