Therefore we need to eliminate the junction thermoelectric to measure to correct Seebeck Voltage and this is called Cold Junction Compensation For most thermocouples the Seebeck Voltage is OV while in 0 C The simple way to cancel the junction voltage is to put the junction into 0 C environment and the junction voltage is OV In general this is not a good method for most application Typical method is to measure the junction temperature by thermistor and measure the junction voltage from the junction temperature that we may get the Seebeck Voltage from measured thermocouple voltage and junction voltage and we may calculate the temperature from the Seebeck Voltage Specifications EX 9018 EX 9018BL EX 9019 EX 90018 M EX 90018BL M_ EX 9019 M Interface RS 485 2 wires Speed bps 1200 2400 4800 9600 19200 38400 57600 115200 Analog Input type Differential input Input Channels 8 Resolution 16 bits Individual channel configuration Not support Support Voltage Input 15mV 15mV 50mV 50mV 100mV 100mV 500mV 500mV 1V 1V 2 5V 2 5V Current Input 20mA 20mA with 125ohms resistor Sensor Input J K T E R S B N Sampling Rate 10 sample second Bandwidth 15 7Hz Accuracy 0 1 Zero Drift 0 5uV C Span Drift 25ppm C CMR 50 60Hz 150dB NMR 50 60Hz 100dB Input Impedance 20M ohms Power supply 10V 30V Modbus RTU EX9018 M
