The 20 301 is an excellent solution for applications involving temperature measurement. With the HART protocol the 20 301 is easily configurable via desktop PC or hand held field configurator. The 20 301 uses a rugged aluminum housing for industrial installations as well as harsh environments. High precision electronics with an advanced thermal compensation process provide optimum performance with RTD and thermocouple sensors. In addition, the 20 301 can also operate transducers with volt signals with outputs ranging from 1mv to 1v, or outputs in Ohms, which by means of a software-controlled current source can read resistance values.
