Holder for a magnet, regulation valve position detector, and regulating valve

A regulating valve position detector for a regulating valve of a process plant, comprising:

• a housing;
• a shaft being rotatably movably supported in the housing, the shaft defining a turning axis;
• and a holder that includes:
• a receptacle configured to hold a magnet within the receptacle, the magnet being over-dimensioned with respect to the receptacle such that a press fit between magnet and receptacle is employed, wherein the receptacle includes first and second sections that are configured to respectively engage first and second opposite ends of the magnet, the first and second sections being completely disjoined and spaced from each other in a mirrored relationship, and a middle portion of the magnet between the first and second ends of the magnet being separated and spaced from both the first and second sections of the receptacle;
• a fixing section connected to the receptacle and configured to turnably fix the holder at the shaft;
• and a support connected to the receptacle and the fixing section, the support configured to latchingly support a rotational spring to generate a rotational spring force on a shaft rotation movement, wherein the rotational spring is oriented parallel to the turning axis and is latchingly self-supported at the housing and the holder.

A holder for a magnet of a magnet sensitive regulating valve position detection device of a regulating valve, the regulating valve position detection device having a shaft turnably movable supported in a housing of the regulating valve position detection device, the shaft defining a turning axis oriented parallel to a rotational spring supporting itself at the housing, and having a lever arm being turnably fixed with the shaft, the lever arm being coupled to the regulating valve in such a way that a regulating valve stroke movement by the lever arm is transferable into a shaft rotation movement, the holder comprising:

• a receptacle configured to hold the magnet within the receptacle, the magnet being over-dimensioned with respect to the receptacle such that a press fit between magnet and receptacle is employed, wherein the receptacle includes first and second sections that are configured to respectively engage first and second opposite ends of the magnet, the first and second sections being completely disjoined and spaced from each other in a mirrored relationship, and a middle portion of the magnet between the first and second ends of the magnet being separated and spaced from both the first and second sections of the receptacle;
• a fixing section connected to the receptacle and configured to turnably fix the holder at the shaft, wherein the fixing section includes a fastener, the holder being connected to the shaft by the fastener;
• and a support connected to the receptacle and the fixing section, the support configured to latchingly support the rotational spring to generate a rotational spring force on the shaft rotation movement.
