We covered how to calibrate the load cell and connect it to the load display in our previous blog. In the process of using the sensor, sometimes we need the standard analog signal of the sensor, so we need a transmitter to convert the mV signal of the load cell into standard industrial signals, such as 0-20mA, 4-20mA, 0-10V, etc. ATO load cell transmitter is the protagonist of our introduction, its output signal is 4~20mA.
