Electrical resistance and conductance sensors measure the resistance or conductance of an electrical component or system. Electrical resistance and conductance sensors are used in a wide variety of industries, across a very broad spectrum of applications. Companies that manufacture resistors, inductors, and chokes often use electrical resistance and conductance sensors to verify that their products meet resistance specifications. Likewise, makers of switches, relays, connectors employ electrical resistance and conductance sensors to make sure that the resistance of contacts does not exceed the specified limits in order to pass quality control. Cable manufacturers frequently use electrical resistance sensors to measure the resistance of the copper conductors in their cables to make sure that their products are capable of carrying the specified current and also to make sure that the appropriate size of conductor is being used in their cables.

Other applications of electrical resistance and conductance sensors include measuring the resistance of welding cables in the automotive industry to make sure that the weld quality remains consistent. In addition, electrical resistance and conductance sensors are often used to test battery leads, the resistance of wiring harnesses and the resistance of crimp-on connectors. Electrical resistance and conductance sensors can be used to detect changes in the earth, water, and materials into which other materials or gases may migrate. As the condition of materials changes, very often so does the electrical conductivity of the material. Personnel who are involved in the installation of electric equipment, cables, switchgear and so forth frequently have a need to use resistive sensors to test the conductivity of cable joints and switch contacts. It is common for preventative maintenance to include routine checks of resistance and conductivity using electrical resistance and conductance sensors.
