The EE65 airflow transmitter is an ideal choice for accurate ventilation control. It operates using an innovative hot-film anemometer, providing high accuracy and low sensitivity to dust.
The EE65 series wind speed transmitter uses an innovative hot‑film sensor that maintains high accuracy even at low air speeds, while being less sensitive to dust and dirt. It provides either current or voltage output, and users can set measurement range and response time via jumpers.
The device operates from a 24 V AC SELV supply, consumes up to 150 mA (AC) or 90 mA (DC), and meets IP65/NEMA 4 protection standards. Various installation options are available, including wall‑mount, duct‑mount, and split‑probe configurations, with optional LCD display models. This manual is written in Chinese.
