This is a telemetry system for dynamic strain measurement using a wireless module of 2.4GHz advanced low-power data communication system. It consists of the transmitter DT-121T and the receiver DT-181R. It is suitable for application where there is some distance between the transmitter and the receiver such as a large testing object or a moving […]
