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)
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 6.5.6)
• Reset functions (see 6.5.6)
• Password activation (see 6.5.6)
• Selecting the language of the display (see 6.5.5)
• Entering of a table function for the linearization of the output signal (see 6.5.4)
• Entering the medium density (see 6.5.4)
