Process conditions
Medium temperature range
The permissible medium temperature depends on the measuring tube liner:
•
Polyurethane, -5° to +125°F (-20° to +50°C) for 1” to 78” sensors
•
Hard rubber, 32° to +180°F (0° to +80°C) for 3” to 78” sensors
Conductivity
Minimum conductivity:
≥
5
µ
S/cm
→
for fluids generally
≥
20
µ
S/cm
→
for demineralized water
Note that in the case of the remote version, the minimum conductivity is also influ-
enced by the length of the connecting cable. Refer to “Length of connecting cable”.
ANSI B 16.5:
Class 150, 1” to 24”
