SUNYUAN Technology plowing intelligent sensors and instrumentation industry analog signal isolation and amplification and transmission technology research and development has been 22 years of experience, during which it has obtained 9 national invention patents, 38 utility model patents and 12 computer software copyrights in the industry.It has been recognized as a national high-tech enterprise for 15 consecutive years since 2007, and has been awarded the qualification of Shenzhen Specialized and Specialized New Enterprise. The company insists on carrying out improvement and innovation work, constantly improve product quality, reduce production costs, expand the scope of application of the product, push the new research and development of new products, in order to adapt to the current electronic information technology before the rapid development of the situation and to meet the customer's product research and development and innovation and upgrading needs.
The development of a small volume, low-cost passive two-wire 4-20mA loop power supply or three-wire power supply output RTD, thermocouple signal intelligent transmitter integration module, can be RTD, thermocouple sensors according to the amount of change in the temperature signal collected, converted into a linear ratio of the standard 4-20mA current or 0-10V/0-5V voltage signal output, internal software calibration without external power supply and potentiometer adjustment and calibration. Internal software calibration without external power supply and potentiometer adjustment calibration, mainly used for three-wire, two-wire Pt100 / Pt1000 / Cu50 RTD or K, E, S, B, J, T, R, N thermocouple temperature sensor signals of intelligent acquisition and transmission.
SY Z-W-O integrated module adopts SunYuan Technology's unique high-efficiency post-feeding invention and patent technology, which can realize the accurate conversion of RTD and thermocouple temperature signals to 4~20mA/0-10V/0-5V standard signals without external power supply, and match with the analog input ports of all kinds of commonly used instruments and meters (e.g., PLC, DCS system, etc.).The product is designed as a low-cost, small volume standard SIP8Pin flame retardant module package, which contains signal conditioning circuit, signal ADC converter circuit, MCU control circuit, digital signal zero, fullness calibration circuit and RTD linearization, long line compensation, interference suppression circuit, and so on.Output circuit supply voltage range (7-35VDC), high conversion accuracy, good linearity, fullness and zero point without user calibration, the internal integration process structure can meet the requirements of industrial grade wide temperature, humidity, vibration, the site of the harsh working environment. Users can use the supporting software or APP to re-configure, change the sensor type and range, and flexibly meet the field requirements.
SY Z-W-O integrated module has a small size, easy to install and use, can be directly placed in the PCB control board or instrumentation meter head, DIN35 rail, armored transmitter inside, the user only needs to add a small number of devices in the periphery, you can realize Pt100 and other RTD, thermocouple sensors, high-precision acquisition and transmission of temperature signals.Among them, the 4-20mA current output module adopts high-efficiency post-feeding technology, which does not require independent power supply, and the two-wire loop power supply output mode can save two power cables, which greatly simplifies the user's design and reduces the user's wiring costs.
