12.8mmPT100 temperature+thermocouple transmitter

Signal isolator, modulated and transformed by semiconductor devices, then isolated and transformed by optical or magnetic sensing devices, and then demodulated and transformed back to the original signal before isolation, while isolating the power supply of the isolated signal. Ensure absolute independence between the transformed signal, power supply, and ground.In industryproduction processImplement monitoring andControl needsUsing various methodsAutomation InstrumentThe signal transmission between the control system and the actuator includes small signals ranging from weak to millivolts and microamperes, as well as large signals of tens of volts, even thousands of volts and hundreds of amperes; There are both low-frequency DC signals and high-frequency signalspulse signalWait, after forming the system, it is often found that signal transmission between instruments and equipment interferes with each other, causing system instability and even misoperation. Apart from the performance reasons of each instrument and equipment itself, such as electromagnetic resistance, this situation may occurInterference impactAnother very important factor is the signal between instruments and equipmentreference pointThere exists between themelectric potential differenceAs a result, a "grounding loop" is formed, causing a signaltransmission processMedium distortion. Therefore, to ensure stable and reliable operation of the system, the issue of "grounding loop" lies in the system signalprocessingThe problems that must be solved in the middle
