Other conditions Other conditions Other conditions Other conditions
Dielectric constant (ε
r
) ≥1.5
Vibration resistance IEC 60068-2-6 and EN 50178 (10...57 Hz: 0.075 mm / 57...150 Hz:1g)
Ingress protection IP 66/67 equivalent to NEMA type 4X (housing) and type 6P (antenna)
Installation conditions
Process connection size The nominal diameter (DN) should be equal to or larger than the antenna diameter.
If the nominal diameter (DN) is smaller than the antenna, either:
– provide the means to adapt the device to a larger process connection on the tank
(for example, a plate with a slot), or
– use the same process connection, but remove the antenna from the device before
installation and fit it from inside the tank.
Process connection position Make sure that there are not any obstructions directly below the process
connection for the device.
