Wireless 4-20 mA transmitter with Tx supply

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. Typical update rates include 1 second, 10 seconds, 60 seconds or 1 hour.

The system also features a signal strength reading and time since last transmission which can be remotely monitored. The IWTxT is designed to operate with the IWR range of receivers. The IWR-1 can output a 4-20 mA or 1-5V signal whilst the IWR-PORT can store up to 128 variables for transmission to an industrial Ethernet connection or an RS-232/485 communications link.
