Load Cell Amplifier Module with 4-20mA 0-5V 0-10V Output

DescriptionBRT RW-ST01A Load cell amplifier amplifies and converts the output signal from full-bridge type load cell or weight sensor into standard dc current or voltage signal. Inside the signal amplifier, there are operation amplification circuit, long-distance compensation circuit, current voltage regulation circuit, linear conversion circuits to process the signal input. Its dc current voltage output can be directly connected to PLC, meters, instruments or other automatic devices for signal data acquisition and controlling. It has good EMC anti-interference capacity, low temperature drift, high sensitivity. This amplifier is widely used in strain gauge or load cell signal amplification and measurement in industrial site.Main Features  • Waterproof design, good sealing of enclosure and cable joint. • High accuracy conversion and amplification circuits embedded. • 4-20mA current and 0-5V or 0-10V voltage signal output is switchable. • Zero and span are easy to be adjusted through potentiometer terminals. • Compatible with all kinds of full-bridge strain gauge bridge-type load cell, such as weighing, tension, compression torque, etc.Technical SpecificationsParameters TYP ValueAccuracy:Better than 0.3% F.S.Loading Capacity:Parallel connection max. 4 x load cells of 350ΩSensitivity:2.0mV/V, ±10%Input Signal :mV Signal, full-bridge load cell sensor signalOutput Signal:Default 4-20mA and 0-5(0-10)V (switchable)Voltage output impedance:>5kΩCurrent output impedance:＜500ΩVoltage Zero adjustment:Fine: 10% F.S.
