FAA-24 ANALOGUE AMPLIFIER

FAA-24 IS A HIGH-PRECISION INDUSTRIAL TRANSMITTER FOR LOAD CELLS.

IT HAS BEEN DESIGNED TO OPERATE PERFECTLY IN ANY AMBIENT CONDITIONS
(FROM –10° TO +50°C). IT IS SUITABLE FOR THE REALISATION OF WEIGHING
SYSTEMS WHERE THE READER IS LOCATED AT SOME DISTANCE FROM THE
MEASURING PLATFORM, OR WHERE THE LOAD CELL SIGNAL SIMPLY NEEDS TO BE
CONVERTED INTO AN OUTPUT INTERFACEABLE WITH ANY ANALOG SIGNAL READER.
THE 24VDC POWER SUPPLY AND THE VERSATILITY PROVIDED WITH THE ZERO AND
SPAN ADJUSTMENT TRIMMERS, AS WELL AS SELECTION OF PRE-TARE AND PRE­SPAN JUMPERS, MAKES IT A FLEXIBLE COMPONENT SUITABLE POR ALL
CONDITIONS AND AT REASONABLE COST. THE TAINLESS STEEL HOUSING OFFERS
THE IDEAL SOLUTION FOR INDUSTRIAL APPLICATIONS WITH IP65 PROTECTION.

Calibration Instruction

1. CARD PREPARATION

TO CALIBRATE THE CARD, THE FOLLOWING IS REQUIRED:

• DIGITAL MULTIMETER WITH MA READING WITH A RESOLUTION OF AT
LEAST 0.01 MA.

• SAMPLE WEIGHT CORRESPONDING TO AT LEAST 50% OF THE CELL CAPACITY
OR THE TOTAL WEIGHT MEASURED BY TEE MEASURING SYSTEM (i.e. IF A
500 KG CELL IS USED TO CARRY OUT A GOOD CALIBRATION, A WEIGHT OF
ABOUT 250 KG MUST BE AVAILABLE.IF, HOWEVER, THE SYSTEM IS MADE
UP OF 4 CELLS OF 500 KG IN PARALLEL, A SAMPLE WEIGHT OF ABOUT
1000 KG MUST BE AVAILABLE),SINCE THE CARD IS EXTREMELY LINEAR,
IT NEEDS TO BE CLARIFIED WHETHER SMALLER KNOWN WEIGHTS MAY ALSO
BE USED WITHOUT PARTICULARLY COMPROMISING THE READING ACCURACY.

2. CONNECTION

• THE POWER SUPPLY TO THE TERMINALS 3-4 (SHIELD TO 5)

• THE MULTIMETER (*) TO THE TERMINALS 1-2

• THE CELL TO THE TERMINALS 11-45

(*) THE MULTIMETER MUST BE SET WITH AN END-SCALE READING OF AT LEAST
25 MA AND MUST BE CONNECTED IN PARALLEL TO THE OUTPUT (OR IF THE CAPD
IS CONNECTED TO A DISPLAY, IT MUST BE CONNECTED IN SERIES TO ANY ONE
OF THE TWO WIRES LEADING TO THE DISPLAY).
