S-Beam Load Cell Explained: Working, Types, Applications & Selection Guide

Image
An S-beam load cell , also known as an S-type load cell , is one of the most widely used force sensors in industrial weighing and process automation systems. It is designed to measure both tension (pull) and compression (push) forces with high accuracy. What Is an S-Beam Load Cell? S-beam load cell designed for accurate tension and compression force measurement in industrial applications The S-beam load cell gets its name from its distinctive “S” shaped body. When a load is applied, the internal strain gauges deform proportionally, producing an electrical signal corresponding to the applied force. Because of this design, S-type load cells are ideal for inline force measurement where compact size and dual-direction loading are required. How Does an S-Beam Load Cell Work? An S-beam load cell works on the principle of strain gauge technology. When force is applied in tension or compression, the strain gauges bonded to the metal element experience deformation. This deformation cha...

What Is Loop Impedance Testing? Importance, Standards & ELCB-Safe Measurement

Image
What Is Loop Impedance Testing and Why Is It Critical for Electrical Safety? Electrical safety in modern installations depends not only on good wiring practices but also on proper testing of protective systems. One of the most important yet often misunderstood tests is loop impedance testing . Loop impedance testing ensures that protective devices such as MCBs, MCCBs, and RCCBs operate fast enough during an earth fault, thereby preventing electric shock and fire hazards. What Is Loop Impedance? Loop impedance is the total resistance of the earth fault current path, starting from the phase conductor, passing through the protective device, and returning via the earth conductor. If loop impedance is too high, insufficient fault current flows and the protective device may not disconnect the circuit in time. Why Loop Impedance Testing Is Mandatory Electrical installation standards require earth fault loop impedance to be low enough to allow protective devices to trip wit...
