process-calibrator

A 4-20mA process control calibrator is a special type of calibration device, and its principles and applications are mainly related to the 4-20mA current signal. Here are the basic principles and main applications: Principles: Current Signal: The 4-20mA process control calibrator uses a current signal ranging from 4 to 20 milliamperes (mA) to represent the measured range. This design has advantages such as insensitivity to cable impedance, ease of long-distance transmission, and strong resistance to interference. Calibration: The 4-20mA process control calibrator can automatically adjust and c
