Siemens SITRANS TR320/420 rail-mounted transmitters seamlessly integrate precise measurement and intelligence in all environmental conditions. Reliability is a given, as demonstrated by the TR420’s dual sensor input, featuring a 4-wire sensor connection and a hot backup function. If one sensor fails, the transmitter automatically switches to the second sensor, ensuring uninterrupted and loss-free data recording.
