According to the working principle of WB series electrical isolation transducer/transmitter, it can be divided into photoelectric isolation type, Hall effect type, frequency conversion type and electromagnetic isolation type. Users can freely choose according to the requirements of system design.
1.1 Photoelectric isolation
This type of AC-isolated sensor/transmitter uses opto-isolated amplification and linear compensation. It features wide frequency response, high accuracy and fast response, e.g. 75mV-500V Input DC Voltage Transducer. Suitable for applications where high accuracy and speed are required, and it can also be used as a broadband isolation amplifier.
1.2 Hall effect type
This type of AC-isolated sensor/transmitter uses the Hall effect principle for electro-magnetic-electrical isolation conversion to sense large currents, e.g. 0-5V Out Hall Effect Current Transducer. Its characteristics are low power consumption, impact resistance, strong overload capability and high reliability. It is especially suitable for high current measurement applications of AC and DC input.
1.3 Frequency conversion type
This type of isolated sensor/transmitter uses frequency modulation and photoelectric isolation. The main features of this type are high precision, good stability, strong anti-interference ability, isolated measurement for DC power and long distance of signal, e.g. 0-100kHz Input 0-5V Output Frequency Transducer. Transmission can be directly matched with non-electrical sensors such as pressure and temperature, and can be used as a high-precision isolation amplifier or a matching transmitter.
1.4 Electromagnetic isolation type
This type of sensor/transmitter adopts the principle of electromagnetic isolation, which is characterized by high precision, good reliability, low power consumption (typical power consumption value is 30mW), small drift, good stability, especially suitable for working frequency to intermediate frequency current, e.g. 10mV-1000V Input Voltage Sensor Low Power. Measurement of voltage, power, etc., or used as a passive AC sampler.
1.5 Smart Transmitter
Smart transmitters generally use dedicated IC chips, MCU technology, high-precision digital conversion technology and special dedicated software algorithms to achieve true rms isolation measurement of electrical parameters, e.g. AC Voltage Sensor With Digital Output. It is characterized by high precision and good stability, and is suitable for accurate measurement of electrical parameters in complex environments. Smart transmitters are generally not affected by harmonic components, and thus have strong anti-interference ability.
