Product outline

High-performance ultra-small load cell converter. These are amplifiers for instrumentation that can stably amplify extremely-small voltage output from the load cell. 100 V AC or 12 V to 24 V 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.
