Load cell amplifier is also known as load cell transmitter. Because the strain gauge load cell can only output mV signal, and this signal is very small and can not be received by common system. So people have designed a dedicated amplifier for the strain gauge load cell, it is the load cell amplifier. The load cell amplifier is suitable for all strain gauge load cells, and can transmit mV signal to standard electrical signal, such as 0-5V/0-10V/4-20mA/0-20mA. Then the signal can be output to PLC, DCS and other systems.
