1.3SMV 3000 Smart Multivariable Transmitters, Continued

SMV Operating Modes The SMV 3000 can transmit its output in either an analog 4 to 20 milliampere format or a Digitally Enhanced (DE) protocol format for direct digital communications with our TPS/TDC 3000 control system. In the analog format, only a selected variable is available as an output which can be any one of the following:

Differential Pressure PV1,

Static Pressure PV2,

Process Temperature PV3, or

Calculated Flow Rate PV4

Note that the secondary variable is only available as a read only parameter through the SCT or SFC. See Figure 2.
