The lock (6) has an oil content (9) up to a level where it is maintained sealed. The oil level can be checked via a transparent level pipe (10), which can also be used for replenishing oil. - The oil lock (6) is connected in a gas-tight manner via a seal (11) with a gas-tight box (13) containing the scales (12). The vibrator (1) is completely encapsulated with a non-magnetic box which is maintained sealed. The box can be of aluminium, stainless steel or brass. Vibrations to the straight bar (2) are transmitted via force fields. |
