An overview of Electrical Isolation Sensor / Transmitter The charge against engineering inspection (monitoring), to improve the system's overall anti-jamming capability, and developed a small volume, high-power test components (products). Power isolation Sensor / Transmitter site can be high current, high voltage, power, frequency, phase angle, degree of electrical parameters of electrical isolation of measurement and conversion, also on a variety of weak signals (such as various bridge signals) isolation amplifier and the transformation of their conditioning, the transformation into line with international standard of voltage, current, frequency, signal, or converted into digital simulation, switch status, and signal output. The output signal can be a traditional pointer instrument phase, but also with modern digital controlled devices, a variety of A / D converter and calculator system directly connected with, and thus can form a highly reliable, industrial inspection (monitoring) or control system. As the power isolation sensor applications, users do not need to do secondary development of high voltage or high current signals can directly access products (through Terminal , And input pin input or perforation), we can get the corresponding output signal. So as a power isolation sensor signal conditioning, isolation and transformation function of the module of the industrial control and data acquisition system ideal transmitter products. With the needle valve continuous development of science and technology, industrial control or detection (monitoring) system to isolate the sensor power requirements are also increasing, especially in product stability, detection accuracy and functionality. As digital products, regardless of their performance and features, such as non-linear correction and small-signal processing, simulation products is unparalleled. Therefore, the power of digital isolation sensor is an inevitable trend. Here on the working principle of power separation sensor and its digital technology to make a brief issues for reference.
