 Model: WZPB-YT01 
 Product Note: Thermocouple order by agreement 
 Category: Integrated Thermocouple Thermocouple → 

 Integrated temperature transmitter generally temperature probe (thermocouple or RTD sensors) and two-wire solid state electronics unit. Solid block form using temperature probe installed directly in the terminal box, to form an integrated transmitter. Integrated temperature transmitter is generally divided into two kinds of thermal resistance and thermocouple types. 
 RTD temperature transmitter is a base unit, R / V conversion unit, a linear circuit, reverse polarity protection, current limiting protection, V / I conversion unit and other components. RTD temperature signal amplified by the linear circuit of the nonlinear relationship between temperature and resistance to compensate, the V / I conversion circuit outputs a linear relationship between the measured temperature of 4 ~ 20mA constant current the signal. 
 Thermocouple temperature transmitters generally by the reference source, the cold-junction compensation, amplification units, linearization, V / I conversion, burnout process, reverse polarity protection, current limiting protection circuit modules. It is the thermocouples produce thermoelectric power amplified by the cold-junction compensation, and then remove cap from the linear circuit and the temperature of the thermoelectric power nonlinearity, zoom into the last 4 ~ 20mA current output signal. To prevent the thermocouple due to broken wires leaving the temperature galvanic failure accident, the transmitter also has a power protection circuit. When the thermocouple broken wire or bad connection solution, the transmitter will output the maximum value (28mA) to make the instrument power off. 
 Normally and display instruments, recording instruments, such as supporting the use of computer output 4 ~ 20mA. Direct measurement of the production process of -200 ℃ ~ 1300 ℃ within the liquid, vapor, gas and solid surface temperature.
