PID temperature controller with multi channel can display temperature and humidity at the same time. PID temperature controller can support not only temperature sensors and humidity sensors, but also various sensors, such as pressure sensors, load cells, displacement sensors, liquid level sensors, gas sensors, and other non-standard sensors.Specification:

PID temperature controller wiring diagram (input: I1+I2 all signals)Tips: Difference between 4-20mA control signal and transmission signal?The instrument can also support 4-20mA (including 0-10mA, 0-10V, 1-5V) as control signal output and transmission signal output. The control signal is used to control the output percentage of the VFD voltage regulating module. While the transmission signal converts the temperature values displayed on the current instrument into linear signal 4-20mA and then passes to PLC, DCS and other devices. Because PLC does not identify Pt100, K/E/J/T these temperature sensors, PLC can recognize the measured value only when it is 'translated' to 4-20mA signal by transmitter.
