Universal Smart Temperature Transmitter

Performance Introduction
可输入单路或双路热电偶、热电阻信号,变送输出隔离的单路或双路线性的电流或电压信号,并提高输入、输出、电源之间的电气隔离性能。 The universal intelligent temperature transmitter can input single or dual thermocouple and thermal resistance signals, transmit and output isolated single or dual current or voltage signals, and improve the electrical isolation between input, output and power performance.


采用了先进的数字化技术,具备了传统模拟仪表所不具备的多项先进性能,在对高、低频干扰信号的抑制方面均有着优异表现,即使在大功率变频控制系统中依然能够可靠应用,同时,数字化技术的应用彻底克服了传统温度变送器线性差的缺点,内部采用数字化调校、无零点及满度电位器、自动动态校准零点、温度飘移自动补偿等诸多先进技术,并符合IEC61000-4-4:1995中所规定的第四类(恶劣工业现场)环境对产品的抗电磁干扰要求,这一系列技术的应用使产品的稳定性及可靠性得到科学的保证。 Technical characteristics The universal intelligent temperature transmitter uses advanced digital technology and has many advanced performances not available in traditional analog instruments. It has excellent performance in suppressing high and low frequency interference signals, even in high-power frequency conversion. The control system can still be used reliably. At the same time, the application of digital technology completely overcomes the shortcomings of traditional linear temperature transmitters. It uses digital adjustment, no zero and full-scale potentiometers, automatic dynamic calibration zero, and automatic temperature drift compensation. And many other advanced technologies, and meet the requirements of the fourth category (harsh industrial site) environment against electromagnetic interference requirements of the product specified in IEC61000-4-4: 1995. The application of this series of technologies has achieved product stability and reliability. Scientific guarantee. zzyfwh.com
