Strain Gauge Signal
Conditioners AC 401, AI 401A, AI 401B |
datasheet |
|
These general purpose
signal conditioners serve to interface strain gauge based
transducers such as load cell, pressure transducer, torque
transducer etc. with recorders, Data Loggers, PC add-on ADC
cards, PLCs etc..
They incorporate stable excitation source and low-noise high
gain amplifiers to provide high level output proportional to the
parameter being measured by the transducers.
AC 401 is in open PCB format and is suitable for OEMs of
instrumentation systems.
AI 401A is the signal conditioner card enclosed in a panel
mounting type of box. It requires a +/-15 V dual DC power
supply. Zero and Span controls are located on its front panel
and the input/ output terminals on its rear panel.
AI 401B is the signal conditioner enclosed in a panel mounting
type of box, which also has mains operated power supply to make
it a stand alone instrument. Zero and Span controls are located
on its front panel and the input/ output terminals on its rear
panel. |
