The AD-4541-V and AD-4541-I analog signal conditioners can convert the signal received
from a bridge type sensor such as a load cell, pressure sensor, strain gauge, etc. to avoltage output (AD-4541-V / -2V to +2V) or a current output (AD-4541-I / 4-20mA).

■ Ultra-slim, lightweight and easy-to-install■ Calibration can be performed with the ZERO / SPAN volume controls or the CAL switch■ Provides a wide-range zero adjustment (±0.5mV/ V) / span adjustment (0.4~3.2mV/V)
for use with various bridge type sensors■ No crimping terminal is necessary because a spring clamp terminal block is used foreasy wiring.
