product manual:

       The integrated digital display temperature transmitter is used in conjunction with industrial thermocouples and thermal resistors, and uses a two-wire transmission method (two wires are used as a common transmission line for power input and signal output). The integrated temperature transmitter converts industrial thermocouple and thermal resistance signals into 4-20mA and 0-10mA output signals that are linear with the input signal or with the temperature signal. It can be directly installed in the junction box of thermocouple and thermal resistance to form an integrated structure.

       technical parameter:

       1. Input signal: thermocouple: K, E, J, B, S, T, N. Thermal resistance: Pt100, Cu50, Cu100 (three-wire system, four-wire system). The input signal of the intelligent temperature transmitter can be set arbitrarily through the handheld device and the PC;

       2. Output signal: output 4-20mA DC signal within the measuring range, linear with the input signal of thermocouple or thermal resistance or linear with temperature. The intelligent temperature transmitter outputs a 4-20mA DC signal while superimposing communication in accordance with the HART standard protocol; isolated temperature transmitter: the input and output are isolated, and the isolation voltage is 500V, which increases the ability to resist common mode interference and is more suitable for connection with a computer. Net use

       3. Basic error: 0.5%FS, 0.2%FS, intelligent 0.2%FS;

       4. Wiring method: two-wire system, three-wire system, four-wire system;

       5. Display mode: Four-digit LCD displays the on-site temperature. The intelligent four-digit LCD can be set by PC or handheld device to display any one of the parameters of the on-site temperature, sensor value, output current and percentage;

       6. Working voltage: ordinary model 12V-35V, intelligent 12V-45V, rated working voltage 24V

       7. Allowable load resistance: 500Ω (24VDC power supply); the limit load resistance R (max) = 50 (Vmin-12), for example, when the rated working voltage is 24V, the load resistance can be used within the range of 0-600Ω.

       8. Working environment:

       a: Ambient temperature -25-+80℃ (conventional type)

       -25-+70℃ (digital display type)

       -25-+75℃ (intelligent type)

       b: Relative humidity: 5%-95%

       c: Mechanical vibration f≤50Hz, amplitude≤0.15mm

       d: No corrosive gas or similar environment;

       9. Environmental impact coefficient: δ≤0.05%/℃.
