This document introduces an advanced temperature transmitter with features of full intelligence, digitalization, and programmability. It can automatically compensate for environmental temperature, zero point, and full range, and has extremely high stability and accuracy. The temperature transmitter meets the electromagnetic interference resistance standards of the International Electrotechnical Commission IEC61000.
The WP-201 is a universal temperature transmitter that accepts thermocouple and RTD inputs, provides dual‑circuit isolation, and offers high‑precision transmission with EMI resistance. It supports multiple output modes such as 4‑20 mA, 0‑10 mA, 1‑5 V, 0‑5 V, and 0‑10 V, and includes optional communication interfaces.
The manual provides detailed technical parameters, wiring diagrams, installation guidelines, programming options, and environmental requirements. It also outlines safety precautions, grounding instructions, and panel indicator functions to ensure reliable operation in industrial settings. This manual is written in Chinese.
