Limit value controllers

Limit switches are used to maintain the safety of systems by defining and monitoring critical levels of process parameters, such as temperature, pressure or flow. When a parameter exceeds the defined limit value, the controller is activated to trigger alarms or interrupt the process to prevent damage to equipment or danger to people. These controllers are often used in processes where it is necessary to protect plant and equipment from potentially harmful conditions, for example in the chemical or oil and gas industries. They ensure that the system does not exceed defined operating limits, reducing the risk of downtime and improving safety.
