Product information Check Stock Global information GO Home lem_current_page : Automation Industrial automation Electrical signals are the power source for all manufacturing processes, machines and systems. In addition, they enable the fast and reliable supervision of equipment and facilities. LEM integrated transducers take this a step further by providing your complete process with increased control and reactivity. They combine advanced sensing technologies and signal conditioning of electronic circuits (True RMS, industry standard outputs e.g. 0-5/10 V or 4-20 mA...).

Product List Contact Sales Application Main applications for Automation Increased process automation efficiencyTraditional process control still implies monitoring and regulation of parameters such as temperature, pressure, torque, position, etc. But measuring these directly can be both inefficient and inaccurate. Measuring the input current of a load provides much more information than just the current value and has a number of advantages like speed, ease of use, reliability, and savings. An increasing number of process automation and condition monitoring applications are following this trend.

Installing electrical transducers in control panels or on electric motor drives allows:

monitoring of the status of various kinds of electro-mechanical installationsregulation of miscellaneous parametersfailure warningback-up system launchTypical applications for AutomationMachine and panel buildersSystem integrators / engineeringSafety operations and personnel protection (Process control: supervision and automation (, smelting furnace, electrolysis process, Electro-mechanical installations monitoring…)Maintenance operations: condition monitoring (Facilities & infrastructures management (, cathodic protection current, drives used to convey materials…)Energy production and consumption ( Site energy sub-metering) Overview Products for automation
