5.1 Potentiometer transmitter characteristics
A potentiometer, a device comprising a printed circuit board on which a reed /resistance chain is
welded, is placed inside the oat’s vertical guide tube.
The total resistance of a known value is measured at the ends of this potentiometer.
The oat, following the liquid level trend, activates the potentiometer’s reed contact chain through
its own magnetic eld, locally closing the signal.
The total value of the resistance, is measured 100% at its maximum level and 0% at its minimum level.
The end poles of the potentiometer are connected to a converter that transforms the input value
into Ohm and the output into mA.
Reading resolution available: 5, 10, 20 mm
Resistance input 1 k ÷ 100 k Ohm. The Ohm-mA signal converters are inside the
housing. Three types of converter are available:
1 Converter for safe zone
2 Converter for inbuilt safety zone, ATEX certied.
3Converter suitable for HART®protocol, suitable
for intrisically safe, ATEX certied
Resistance input 1 k ÷ 100 k Ohm
Current output 4 ÷ 20 mA
Type 1and 2 converters can be eld set using two
trimmers [for the Z (zero) gauging and G (Gain)
gauging], without resorting to interconnecting
systems.
The type 3converter must be regulated with an
interconnection cable.
