Design of Wireless Multi-Channel Measurement System

We are developing a wireless multi-channel measurement system in order to measure temperatures during thermal vacuum tests of spacecraft, accelerations during vibration tests, etc. As a developing measurement system, we introduce the prototype model of the wireless temperature measurement system. The temperature data are transmitted to the data logger by radio instead of thermocouple wires, thus it will be easier to prepare thermal vacuum tests, and the test system will become very simple. Details of the system configuration, its specification and performance are presented.
