The ARD154 is a DIN rail mountable amplifier, which
adapts to most strain gage-based load cells, pressuretransducers and accelerometers. The bridge supply voltage
can be set to 5V or 10V ±10V analogue output signals or 0/420mA current outputs. It covers sensitivity range from 0.1mV/V
to 30mV/V. It also allows connecting four 350  sensors inparallel with 5Vdc excitation.
Through its modular design, the ARD154 adapts tomany different applications. Basic settings with onboard
jumpers includes:
Bridge supply voltage
BandwidthSignal output for voltage or current
Zero and Gain adjusting is facilitated by trimmers on
the front panel.

APPLICATIONS

Monitoring devices
Weighing
Robotic and effectors
Laboratory and Research
