Basics of Strain Gauge Measurements

Last Updated on May 20, 2026 by Swagatam 2 Comments

wheatstone bridge circuit

The strain gauge is one of the most useful tools for precisely measuring expansion or contraction of a material as forces are applied. Strain gauges are also useful for measuring applied forces indirectly if they are aligned approximately linearly with the deformation of the material. What are Strain Gauges Strain gauges are sensors whose electrical […]

Low Battery and Overload Protection Circuit for Inverters

Last Updated on December 18, 2024 by Swagatam 254 Comments

overload protector circuit

A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions. […]
