FAA-27

Microcontroller based analog load cell transmitter FT-27 has very high accuracy and long term stability with its high tech design. Its high performance electronic calibration via RS232C serial port without any test weight and fast calibration without measuring output signal give big advantage to the users for calibration scales.

This high tech instrument gives the system designers a lot of advantages to increase the system reliability and to reduce the installation and service times. Besides the traditional analog output adjustment with any test weight, the electronic calibration eCal and fast calibration with 20% max. test load reduces the calibration time. All analog outputs of instruments are matched in the production to perform calibration at PLC and for changing the instrument without recalibration in service.

There are 8 positioned rotary switches and annunciator LEDs in front of the instrument. The front view and pin descriptions of FT-27 is shown below.

Features

 Minimized zero and span drifts due to its microcontroller technology and high

accuracy, very low temperature drift, 24 bits ADC and 16 bits DAC converters.

 Long time stability and low temperature drifts eliminate the frequent

readjustment period.

 Very easy and user friendly digital adjustment via rotary switches located on

the front of the instrument.

 Programmable digital adaptive anti-vibration filters to minimize environmental

vibrations.

 eCal- electronic calibration without weights and digital filter adjustment via

RS232C port and xFace PC software.

 Fast calibration feature to reduce the adjustment time and to minimize

adjustment error.

 Calibration at PLC does not require readjustment after changing instrument

because of matching in the production.

 2 pcs free relay contact output for alarm or controlling valves, gate etc.
