Technical Specifications

1. Input signal: Thermocouples: 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 a handheld device and a PC;

2. Output signal: Output a 4-20mA DC signal within the range of measurement, which is linear with the input signal of the thermocouple or thermistor or linear with temperature. The intelligent temperature transmitter outputs a 4-20mA DC signal and superimposes it with communication in accordance with the HART standard protocol; Isolated temperature transmitter: The input and output are isolated, with an isolation voltage of 500V, which increases the resistance to common mode and is more suitable for networking with computers;

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

4. Wiring methods: 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 through a PC or handheld device to display any of the parameters including on-site temperature, sensor value, output current, and percentage;

6. Working voltage: Ordinary model 12V-35VDC, intelligent model 12V-45VDC, rated working voltage is 24VDC;
