S.12. Potentiometer (MTP10)
S.13. Differential Pressure Transmitter (PDT75)
S.14. Differential Manometer
Systemair potentiometers which are supplied as an option vary voltage output by altering the resistance in the electrical circuit.
When a change is made in the potentiometer, the frequency inverter is initialized to bring the static pressure above or below the
staticpressuremeasuredinthepressuredifferentialtransmitter,changingthefanspeed.Inthisway,youcansetanyowrateyou
wish, provided that it does not exceed the capacity range of the fan or of the fan motor.
The differential pressure transmitter measures the difference in static pressure between the intake and discharge of the fan
section, and transmits this information to the frequency driver.
The differential manometer which is supplied with automation measures the difference in static pressure between the intakes and
dischargesofsectionswhereinltersarehoused.Whenthisdifferencereachesthepresetvaluesayelloworredlampcomesonon
thepanel,indicatingthatyouneedtoreplacelters.
