AE520-TB intelligent temperature transmitter is a super-compact, excellent performance, high-precision temperature meter produced by Beijing Huaxia Anyi Technology Co., Ltd. It is powered by a battery, has a digital display, and has the characteristics of small size, light weight, and easy use and installation. It converts the temperature parameters of the controlled object into an electric signal, and transmits it to the display, recording, and regulating instruments to control the system for detection, regulation, and control. It can be directly installed in the terminal box of general industrial thermocouples and thermocouples, and constitutes an integrated structure with the on-site sensing element. This not only saves compensation wires and cables, but also reduces signal transmission distortion and interference, thus obtaining high-precision measurement results.
