Alarm systems utilize a combination of sensors, controllers, and communication technologies to continuously monitor the reaction parameters. Here is a simplified overview of how they work:
Sensors: These devices measure specific parameters such as temperature, pressure, and concentration. Common sensors include thermocouples, pressure transducers, and spectrometers. Controllers: These devices receive data from the sensors and compare it to predefined setpoints. If a deviation is detected, the controller triggers an alarm or corrective action. Communication Systems: These systems transmit data from the sensors and controllers to a central monitoring station or control room, where operators can take appropriate actions. Actuators: In some systems, actuators are used to automatically adjust reaction conditions (e.g., opening/closing valves, adjusting flow rates) in response to alarms.
