Product Description:

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

Technical parameters:

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 intelligent temperature transmitter can be set by hand and PC.

2, output signal: output 4 - 20mA DC signal in the range, linear with the thermocouple or thermal resistance input signal, or linearly with temperature. The intelligent temperature transmitter outputs 4 20 mA DC signals and superimposes HART standard protocol communication at the same time. The isolated temperature transmitter is isolated from input and output, Isolating voltage 500V, increasing the ability of resisting common mode interference, and is more suitable for networking with computers.

3, basic error: 0.5%FS, 0.2%FS, intelligent 0.2%FS;

4, wiring mode: two-wire system, three wire system, four wire system;

5, display mode: four bit LCD display site temperature, intelligent four bit LCD can be set through PC or handset to display any parameters of site temperature, sensor value, output current and percentage percentage.

6, working voltage: general model 12V-35V, intelligent 12V-45V, rated working voltage is 24V

7, allowing load resistance: 500 ohms (24VDC power supply); limit load resistance R (max) =50 (Vmin-12), for example, when rated operating voltage 24V, load resistance can be selected in 0-600 ohms.

8, working environment:

A: ambient temperature -25-+80 C (conventional type)

-25-+70 C (digital display)

-25-+75 C (intelligent)

B: relative humidity: 5%-95%

C: mechanical vibration f is less than 50Hz, amplitude is less than 0.15mm

D: no corrosive gas or similar environment;

9, the environmental impact coefficient: Delta is less than 0.05%/ degrees.
