17 Inputs
17.1 Binary Inputs
The transmitter can be equipped with 1 or 2 binary inputs. Using the binary outputs, it is possible to remotely trigger some
functions of the transmitter (see section 11.10).
17.2 Analog Inputs
External sensors can be connected to the inputs (optional) to measure the following physical quantities:
• temperature
• density
• pressure
• kinematic viscosity
• dynamic viscosity
The values of the current, voltage, and temperature inputs can be used by all measuring channels.
An input has to be assigned to a measuring channel (see section 17.2.1 and 17.2.3) and activated (see section 17.2.4) be-
fore it can be used for the measurement and for the storing of measured values.
Depending on the configuration of the transmitter, one or several of the following list items will be displayed:
17.2.1 Assignment of the Temperature Inputs to the Measuring Channels
For the assignment of the temperature inputs during the heat flow measurement see chapter 16.
Enter the list items
T(3)
and
T(4)
if additional temperature values besides the medium temperature are to be measured
and stored. These additional temperature values will not be used for the calculation of the selected physical quantity.
Repeat the steps for the other activated channels accordingly.

• Select the temperature input to be assigned to measuring channel A as the medium tem-
perature. The temperature value will be used for the calculation of the selected physical
quantity.
• Select the list item

fore the measurement.
• Select the list item

if no temperature is to be assigned to measuring
channel A.
Press ENTER.
Note! The configuration of a measuring channel will be stored when the next channel is selected. The con-
figuration dialog for a channel has to be completed in order to store the changes.
