Abstract
The invention concerns a fluid rotary machine (1) with a housing (2), a shaft (3) projecting from the housing (2), and being rotatable around an axis (4) and forming part of a movement chain, and a sensor arrangement (10) comprising a transmitter (12) and a receiver (15). It is endeavoured to find a simple solution for detecting the rotation of the shaft with a relatively high accuracy. For this purpose, a channel (21) is provided in the movement chain, and the transmitter (12) is connected to a transfer element (19) transferring a torque that is led through said channel (21) to a section of the movement chain that is farther away from the transmitter (12) than a transmitter-side end of the movement chain.
