IWTxT Series Wireless Transmitter IWTxT-00
Industrial IoT Hardware
The IWTxT is designed to convert any standard 4-20 mA transmitter into a wireless unit. It works by switching on a supply to the 4-20 mA transmitter, waiting for a suitable settling time and then sending the data to one of Sensata’s standard wireless receiver units.
The IWTxT is specially designed to maximise battery life and in a typical application the battery life will exceed 12 months.
The data update rate is user selectable to suit the requirement of each measured variable and so maximize battery life.
