Let me briefly introduce the integrated temperature transmitter
具有结构简，节省引线，输出信号大，抗干扰能力强，线性好，显示仪表简单、固体模块抗震防潮，有反接保护和限流保护，工作可靠等特点：为了防止热电偶测量中由于电偶断 1.The integrated temperature transmitter has the advantages of simple structure, saving leads, large output signal, strong anti-interference ability, good linearity, simple display instrumentation, solid module shock and moisture resistance, reverse connection protection and current limit protection, reliable operation : To prevent the thermocouple from being disconnected during thermocouple measurement
The failure of temperature control caused an accident. The transmitter also has a power-off protection circuit. When the thermocouple breaks the wire or the connection is poor, the transmitter will output the maximum value (28mA) to make the meter cut off the power.
一般由测温探头（热电偶 2. The thermocouple temperature transmitter "capacitive level transmitter" is generally composed of circuits such as reference source, cold junction compensation, amplification unit, linearization processing, V / I conversion, disconnection processing, reverse connection protection, current limit protection, etc. Unit composition; integrated temperature transmitter generally consists of temperature measuring probe (thermocouple
Or thermal resistance sensor) and two-wire solid electronic unit;
3. It can be matched with microcomputer system or other conventional instruments for use;
It can also be made into explosion-proof or fire-proof measuring instruments by users' requirements! 的输出为统一的4～20mA信号 The output of the integrated temperature transmitter is a uniform 4 ～ 20mA signal
