Abstract
A field device for sensing at least one process parameter, the field device comprising a sensing arrangement configured to provide a sensing signal indicative of the at least one process parameter; a housing at least partly enclosing the sensing arrangement; and a vibration damping arrangement including an elastomeric member and a counter vibration weight coupled to the housing via the elastomeric member, the counter vibration weight comprising: a first part attached to the elastomeric member; and a second part movable in relation to the first part to allow tuning of the vibration damping arrangement.

A field device for sensing at least one process parameter, the field device comprising:
- a sensing arrangement configured to provide a sensing signal indicative of the at least one process parameter;
- a housing at least partly enclosing the sensing arrangement;
- and
- a vibration damping arrangement including an elastomeric member and a counter vibration weight coupled to the housing via the elastomeric member, the counter vibration weight comprising:
- a first part attached to the elastomeric member;
- and
- a second part movable in relation to the first part to allow tuning of the vibration damping arrangement.
A method of configuring a field device having a housing, comprising:
- providing the field device;
- providing a vibration damping arrangement comprising:
- an interface member configured to be attached to the housing of the field device;
- an elastomeric member attached to the interface member;
- a first part of a counter vibration weight attached to the elastomeric member, in such a way that the first part of the counter vibration weight is coupled to the interface member via the elastomeric member;
- and
- a second part of the counter vibration weight movably attached to the first part of the counter vibration weight;
- tuning the vibration damping arrangement;
- and
- fixing the vibration damping arrangement to the field device by attaching the interface member of the vibration damping arrangement to the housing of the field device.
