Ensuring Safe Operation of Equipment In industrial production, pressure sensors monitor the pressure changes within equipment in real-time. When the pressure exceeds the safety threshold, they quickly transmit signals to the control system, triggering alarms or automatic shutdown mechanisms to prevent equipment damage due to overpressure, effectively avoiding safety accidents. Foundation of Automation Control Electric … Read more
