Product Overview

This differential pressure/wind pressure transmitter uses high-quality components from a German company. It adopts a normalized circuit design and assembly process, together with unique sensor stress isolation technology. Through temperature compensation and high-stability amplification, it converts the differential pressure signal of the measured medium into a standard 4~20mA DC or 1~5V DC signal. High-quality sensors, normalized circuit design, advanced packaging technology, and refined assembly processes ensure the product’s excellent quality and optimum performance. This series of products is specially designed for industrial and civil OEM customers, establishing a new price-performance standard.

Notes 1. All supplied products come with a certificate of conformity and an instruction manual containing the product number, technical parameters, wiring diagrams, factory date, and other information. Please check them carefully to avoid incorrect use. 2. Wiring must be carried out strictly according to our company’s operating instructions. 3. This product is a precision instrument. Do not disassemble it without authorization, subject it to impacts or drops, or poke the sensor with sharp instruments. 4. The transmitter can operate immediately after being powered on, but its output becomes stable after 30 minutes of preheating. 5. If any abnormality is detected during use, turn off the power, stop using the product, and conduct an inspection, or contact our technical department directly. 6. During transportation and storage, restore the original packaging and store the product in a cool, dry, and well-ventilated warehouse. 7. The quality warranty period is 12 months (damage caused by improper use, such as pressure overload or incorrect wiring, is not covered by the quality warranty). 8. Special products are customized products and are not eligible for no-reason returns within 7 days. Customized products have a lead time and cannot be returned or exchanged.
