The limiting factors of electromechanical switches

摘要

From pharmaceutical to oil and petrochemical industries and many more, process control greatly depends on two physical variables: temperature and pressure. While a wide range of sensors are available for temperature and pressure control in process automation applications, the simplest solution is often an electromechanical switch.rnThese passive components detect changes in temperature or pressure and open or close a contact when a specified level is reached. The switches directly activate power without requiring an interconnected controller or electronic circuit, delivering an easy-to-use, cost-effective solution for a broad range of applications.
