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.
|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.
Non-linearity: within 0.02% FS
Zero drift: within 1μV/°C RTI
Gain drift: within 0.01%/°C
Noise: within 1μVp-p RTI (2Hz)
|Output signal||Voltage output: 0 to ±10V, Load resistance: 2kΩ or more
Current output: 4 to 20mA, Load resistance: 500Ω or less
|Low-pass filter||Low-pass filter (-6dB/oct.) 2Hz/-3dB|
|Power supply voltage||100V AC ±10%, 50/60Hz
12 to 24V DC ±15% (LC1111[DC])
With regard to AC or DC specifications, please specify when ordering.
