Front View, Features and Specifications
Microcontroller based analogue load cell transmitter FAA-26 has very high accuracy
and long-term stability with its state-of-the-art design.
This high accurate instrument gives the system designers a lot of advantages to
increase the system reliability and to reduce the installation and service times. All
instrument
s’ analogue outputs are matched in the production to perform calibration at
PLC and for changing the instrument without recalibration in service if the adjustment
is done in a PLC.
There are 2 rotary switches and annunciator LEDs in front of the instrument.
The upper rotary switch adjusts
unloaded scale’s analogue output level (zero
adjustment) and the lower rotary switch adjusts the gain of the instrument. The front
view and pin descriptions of FAA-26 are shown below.
