Abstract
A force measurement device for a fluid control valve is disclosed, in which a force measurement device is coupled between a driving axle of a driver device and a valve rod of a fluid control valve. The force measurement device includes a sensor seat, which is coupled between the driving axle of the driver device and the valve rod of the fluid control valve. A plurality of stress detection units are arranged and positioned on the sensor seat in an annular configuration and are spaced from each other by an angle. The plurality of stress detection units are operable to measure a magnitude of a force applied to the valve rod according to deformation of the sensor seat and generates a plurality of stress variation signals that are transmitted to a control device.

A force measurement device for a fluid control valve having a valve rod connected to a driver device, the driver device comprising a driving axle that drives the valve rod of the fluid control valve, the force measurement device being coupled between the driving axle of the driver device and the valve rod of the fluid control valve, comprising:
- a sensor seat coupled between the driving axle of the driver device and the valve rod of the fluid control valve;
- a plurality of stress detection units arranged and positioned on the sensor seat in an annular configuration and are spaced from each other by an angle, the plurality of stress detection units being operable to measure a magnitude of a force applied to the valve rod according to deformation of the sensor seat and generating a plurality of stress variation signals that are transmitted to a control device;
- and
- a coupling seat fastened between the fluid control valve and the driver device by a plurality of fastener elements, the coupling seat comprising:
- a first opening that is adjacent to and corresponding to the driver device to receive extension of the driving axle of the driver device therethrough,
- a second opening that is adjacent to and corresponding to the fluid control valve to receive extension of the valve rod of the fluid control valve therethrough, and
- a sensor seat accommodation space that receives and holds the sensor seat therein.
