A Data Logger is an instrument that continuously records and stores measurements from sensors, such as temperature, pressure, humidity, or voltage, over time for analysis and monitoring. The main types include standalone data loggers (portable, battery-operated for field use), wired or networked loggers (connected to PLC/DCS systems), and wireless or IoT-enabled loggers (for remote monitoring and cloud-based data access). Data loggers are widely used in industries such as pharmaceuticals, food & beverage, chemical processing, and energy for process monitoring, quality control, regulatory compliance, and predictive maintenance.
