|| The small and light sensor with its durable reinforced polyamide plastic body is attached to the 5.5-7 mm power cord. Without interfering with the performance of work, it measures real-time consumption data and trigger time; it then transfers them to SensorLink Gateway. The sensor is equipped with silver oxide primary cell batteries with a lifetime of up to 2 years. Its small and light design ensures there is no interference with the performance of work. It is built to record real-time trigger time and stock distribution information for theft prevention.
