observe the application limitation for flange system WS
Application restrictions, flange system WS:
(1)
If the operator cannot rule out the risk of electrostatic charging of the antennas,
the antennas may only be used in conjunction with Gas Group II B.
(2)
To reduce the maximum allowable tank pressure, where flange and product
temperatures are > 100°C, see the following formula and table.
(3)
If the operator cannot rule out the risk of electrostatic charging of the antennas,
the antennas may only be used in Zone 1/Gas Group II B.
(4)
Limitation to atmospheric conditions in accordance with EN 60079-26
(5)
By using the standard microwave window of stainless steel (Type SS) the
allowed flange / product temperature is minimum -30 °C.
