    Abstract: A dynamic torque sensing device of a thread-on freewheel structure includes a thread-on freewheel sensing body (1), a stationary housing (2) and a sensor (12). The thread-on freewheel sensing body and the stationary housing are rotatable relative to each other, and the sensor is configured to sense a torque of the thread-on freewheel sensing body. The thread-on freewheel sensing body includes a thread-on freewheel sensing body relatively stationary portion (101), a thread-on freewheel sensing body relatively rotating portion (102) and a thread-on freewheel sensing body intermediary portion (103). The thread-on freewheel sensing body relatively stationary portion, the thread-on freewheel sensing body intermediary portion and the thread-on freewheel sensing body relatively rotating portion are sequentially arranged along an axial direction of the thread-on freewheel sensing body. The thread-on freewheel sensing body intermediary portion is configured to connect the thread-on freewheel sensing body relatively stationary portion to the thread-on freewheel sensing body relatively rotating portion.

    Abstract: A hoist main shaft torque monitoring device based on angle measurement, constituted primarily by a first base, a second base, a light generating unit, a shutter, and a light sensing element; the light source, a first lens, and a first optical aperture arranged in the light generating unit, as well as a second optical aperture, second lens, and light sensing element on the shutter, forming a light source generation, propagation, and reception pathway; when the elevator main shaft is subjected to a certain torque, a corresponding displacement is produced between the first optical aperture and the second optical aperture, thus measuring the change in amount of light ultimately reaching the second optical aperture so as to measure the twist angle of the rotary shaft and finally calculate the magnitude of the shaft torque. Without damaging the original equipment and foundation, the device measures the torque of the shaft at different rotational speeds. The device can measure stationary torque and torque at different rotational speeds of the shaft, without the electromagnetic field interfering with wireless transmission; the device is easy to use, maintenance costs are low, and it is of interest for widespread popularization.

    Abstract: A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate.
