UNIPULSE – Plug-in Type Loadcell Converter LC1111
Brand: Unipulse
Model: LC1111
 
Products Description:
High-performance ultra-small loadcell converter. These are amplifiers for instrumentation that can stably amplify extremely-small voltage output from the loadcell. 100V AC or 12V to 24V DC can be specified when ordering. Equipped are the bridge excitation power supply, a zero gain adjustment circuit, calibration function, voltage/current output function and a low-pass filter.

Technical specification:

Excitation voltage	5V±5% DC, Output current: within 60mA (Up to 4 loadcells at 350Ω are parallel-connectable.)
Zero adjustment range	±0.4mV/V (bridge resistance: 350Ω) 20 turn trimmer potentiometer Expandable by external resistance connection if the above range is exceeded.
Gain adjustment range	0.6mV/V to 1.4mV/V (HI range) 1.3mV/V to 3.2mV/V (LO range) Switching is performed by internal jumper.
