Transmitters with displa

s offer a lar

er number of pro

rammin

and processin

op-

tions. These options include alarm status, dampin

, si

nal inversion, tank lineariza-

tion and dia

nostic messa

es.

2.2 Function

The mode of operation for si

nal conversion works in the same wa

for all versions.

The pressure transducer converts the existin

pressure into an electrical si

nal. Mi-

croelectronics further process the input si

nal and produce a proportional 4-20 mA

standard si

nal.

The displa

-version allows pro

rammin

(parameterization) and the displa

of ex-

tended functions such as inversion, dampin

, 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 (dr

adjustment) (see 5.4)

• Settin

the dampenin

/ inte

ratin

the output si

nal 0-40 s (see 5.5)

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

• Mountin

correction of the sensor (be

innin

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 displa

(see 6.5.1)

• Nominal pressure ran

e of the sensor shown in displa

(see 6.5.1)

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

• Settin

of dampin

/ inte

ration of output si

nal 0-40 s (see 6.5.3)

• Inversion of the output current si

nal (see 6.5.3)

• Settin

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

• Settin

the limits of the output si

nal (see 6.5.3)

• Offset of the output si

nal (see 6.5.3)

• Mountin

correction of the sensor

• Measurin

circuit test function (see 6.5.4)

• Reset functions (see 6.5.4)

• Password activation (see 6.5.4)

• Selectin

the lan

e of the displa

(see 6.5.5)

• Enterin

of a table function for the linearization of the output si

nal (see 6.5.6)

• Enterin

the medium densit

(see 6.5.6)

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