Siemens Sitrans TR320 temperature transmitter 7NG03200BA000AA0-Z

SITRANS TR320 and TR420 rail transmitters combine perfect measurement and intelligence under all conditions. Reliability is guaranteed, for example, by the TR420's 2-fold sensor input including 4-wire sensor connection and hot backup: In the event of a sensor failure, the transmitter automatically switches to the second sensor, and the values ​​continue to be recorded seamlessly and without loss.
