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”
