1 Introduction
The Rosemount 326T Temperature Transmitter detects media temperature and converts
it into an analog output signal (4 - 20 mA).
1.1 Functions and features
The temperature transmitter converts the measured signal into a temperatureproportional analog signal. Depending on the parameter setting, the output signal is:
• 4-20 mA with setting OU = I
• 20-4 mA with setting OU = Ineg
The temperature transmitter can scale the analog signal to accommodate the application.
For more technical data, see the Rosemount™ 326T Temperature Transmitter Product
Data Sheet or Emerson.com/Rosemount.
Maximum measuring range when OU = I
• MAW = initial value of the measuring range
• MEW = final value of the measuring range
Note
The minimum difference between ASP and AEP is 9 °F (5 °C).
If the temperature is within the measuring range, the output signal is between 4-20 mA. If
the temperature is outside the measuring range, the output signal is between these
ranges:
Measuring range scaled when OU = I
• ASP = analog start point
• AEP = analog end point
Temperature condition
Temperature > AEP 20-20.6 mA 4-3.7 mA
Temperature > MEW 20.6 mA 3.7 mA
Temperature < ASP 4-3.7 mA 20-20.6 mA
