The Smar TT302 FOUNDATION Fieldbus or the TT303 PROFIBUS PA Temperature Transmitter are also called universal because they can read use inputs that provides millivolts or resistance that can be interpreted as a physical measurement. Herein, we show how to connect one or more sensors to the terminal block of these temperature transmitters. The terminal…

The Smar TT301 HART® Temperature Transmitter is also called universal because it can read inputs that provides millivolts or resistance that can be interpreted as a physical measurement. Herein, we show how to connect one or more sensors to the terminal block. The terminal block has 4 terminals dedicated to the sensor(s) connections. (see details…

Initial Note:   DT300 refers for the SMAR family of Density Transmitters that can be found with 3 available communication protocols. The DT301 is the HART model that also provides the 4-20 mA output, the DT302 for FOUNDATION Fieldbus, and the DT303 for Profibus PA.   Introduction Many industrial processes need continuous density measurement to…
