Transmitters with displays offer a larger number of programming and processing op-
tions. These options include alarm status, damping, signal inversion, tank lineariza-
tion and diagnostic messages.

2.2

Function

The mode of operation for signal conversion works in the same way for all versions.
The pressure transducer converts the existing pressure into an electrical signal. Mi-
croelectronics further process the input signal and produce a proportional 4-20 mA
standard signal.

The display-version allows programming (parameterization) and the display of ex-
tended functions such as inversion, damping, alarm status and linearization.

2.2.1

Functions of Transmitters without Displays

• Calibration of zero and span under pressure (see 5.3)

• Calibration of zero and span without pressure (dry adjustment) (see 5.4)

• Setting the dampening / integrating the output signal 0-40 s (see 5.5)

• Reset to manufacturer’s default values (see 5.6)

• Mounting correction of the sensor (beginning with software version 1.05)

(see section 5.4.3)

2.2.2

Functions of Transmitters with Displays

• Settable units of measurement (mbar, bar, psi, mA, %, m, mm WS) (see 6.5.1)

• Temperature and Min/Max values shown in display (see 6.5.1)

• Nominal pressure range of the sensor shown in display (see 6.5.1)

• Zero and span calibration (with/without pressure) (see 6.5.2)

• Setting of damping / integration of output signal 0-40 s (see 6.5.3)

• Inversion of the output current signal (see 6.5.3)

• Setting the output current value in case of alarm (3.6 mA or 21 mA) (see 6.5.3)

• Setting the limits of the output signal (see 6.5.3)

• Offset of the output signal (see 6.5.3)

• Mounting correction of the sensor

• Measuring circuit test function (see 6.5.4)

• Reset functions (see 6.5.4)

• Password activation (see 6.5.4)

• Selecting the language of the display (see 6.5.5)

• Entering of a table function for the linearization of the output signal (see 6.5.6)

• Entering the medium density (see 6.5.6)

Display units can be easily upgraded (see chapter 4.2).
