‘Torque transducers and torque sensors explained’
As this article from Applied Measurements explains, torque is a twisting or turning force about an axis that can be applied in a clockwise or counterclockwise direction. A good example of this is a vehicle steering mechanism; to turn a corner, the driver applies a force to the steering wheel that applies a torque directly to the steering column. This torque is generated by a combination of the force from the driver’s hands and the distance the hands are from the centre of the wheel.

As this article from Applied Measurements explains, a linear variable differential transformer (LVDT) is an electromechanical transducer that converts the linear motion of the object to which it is coupled mechanically in a corresponding electrical signal. The basic design consists of a cylindrical array with a primary winding centred between two identically wound secondary windings. The coils are wound on a hollow glass-reinforced polymer (GRP) former, which is surrounded by a high-permeability
This technical article from Applied Measurements focuses on pressure sensors. Typically, a pressure sensor is used to measure the pressure of fluids (gases or liquids). Pressure is an expression of the force required to stop a fluid from expanding and is usually stated in terms of force per unit area. A pressure sensor generates an electrical signal relating to the pressure imposed. Such a signal is normally digital or analogue, although optical, visual and auditory signals are also ...
This technical article from Applied Measurements focuses on the loadcell — a transducer that converts the load acting on it into a measurable (analogue or digital) output. The output is proportional to the force or load applied.
