SBWR, SBWZ series thermocouple, RTD temperature transmitter is DDZ series of instruments in the field mounted temperature transmitter unit, and industrial thermocouple, RTD supporting the use, it uses two-wire transmission mode (two wires for power Public input and signal output transmission line). The output signal of industrial thermocouple, RTD signal into the input signal or temperature signal into a linear 4-20mA, 0-10mA's.
The temperature transmitter can be mounted directly on the thermocouple, thermal resistance of the junction box with the formation of integrated structure. It is a new generation of Thermometer can be widely used in metallurgy, petroleum, chemical, power, light industry, textile, food , defense and scientific research industries.
1, the input signal: Thermocouple: K, E, J, B, S, T, N. RTD: Pt100, Cu50.
Cu100 (three-wire, four-wire system).
2, the output signal: 4-20mA output within the range DC signal, and thermocouple or RTD input signal into a linear or linear with temperature isolation temperature transmitter: input and output are isolated, isolation voltage 500V, increased resistance to common mode interference ability, more suitable for use with computer networking;
3, the basic error: 0.5% FS, 0.2% FS;
4, wiring: two-wire, three-wire, four-wire system;
5, Display: four LCD display field temperature;
6, the working voltage: Common Model 12V-35V, rated working voltage of 24V
7, allowing the load resistance: 500Ω (24VDC power supply); limit load resistance R (max) = 50 (Vmin-12), for example, at the rated working voltage 24V, load resistance can choose to use within 0-600Ω range.
8, the working environment: temperature -25- + 80 ℃ (conventional type); -25- + 70 ℃ (digital display type).
