Hello biagiodim; All HART-enabled transmitters allow the Primary Variable selected to be read out as a 4-20 mA signal if you choose to not use HART communications. "The transmitter emits the output current according to the device variables selected as primary variable (PV). The operating range of the current lies between 4 mA and 20 mA." - Sitrans P300 with HART communication: https://support.industry.siemens.com/cs/ww/en/view/22145531 You use the P300 keyboard to select which of the measured values is used as Primary Variable: "The following device variables are available: • Pressure • Sensor temperature • Electronics temperature • Pressure (untrimmed)" Hope this helps, Daniel Chartier |
