‘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.

Applied Measurements has introduced the CCG series of annular loadcells. These annular or doughnut loadcells have been designed for the measurement of compressive forces, both continually and periodically, and are often used in critical bolted installations to monitor bolt tension.
Applied Measurements has designed a bespoke bridge monitoring system for Turkey’s Marmaray Tunnel project. Using AML/SGD strain-gauge displacement transducers, the tunnel provides a direct link between Halkali on the European side of Istanbul and Gebze on the Asian side.
Applied Measurements has revealed how its compact and submersible DSCC loadcells have been used on the Mantis hydraulic all-terrain hexapod robot.
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 ...
