Degree of protection • Standard: IP 67 (NEMA 4X) for transmitter and sensor

• Optional: IP 68 (NEMA 6P) for sensor in remote version

Shock and vibration resistance Acceleration up to 2 g by analogy with IEC 60068-2-6.

Electromagnetic compatibility

(EMC)

To EN 61326/A1 and NAMUR recommendation NE 21.

Process conditions

Medium temperature range The permissible medium temperature depends on the measuring-tube lining:

• 0...+80 °C for hard rubber (DN 65...2000)

• −20...+50 °C for polyurethane (DN 25...1000)

Conductivity Minimum conductivity:

≥ 5 µS/cm for liquids generally

≥ 20 µS/cm for demineralised water

Note that in the case of the remote version, the minimum conductivity is also influenced by the length of the

connecting cable → see “Length of connecting cable”
