The EE65 series is the ideal choice for accurate ventilation control applications. It is based on an innovative thermal film anemometer. The thin-film sensor from Endress+Hauser ensures high accuracy even at low air velocities, which cannot be achieved by conventional anemometers using standard temperature sensors or NTCs. In addition, this sensor is less sensitive to dust and dirt than other sensors, so measurements are more reliable and maintenance costs are low. The EE65 series offers current or voltage output signals, and users can select the measuring range and response time using jumpers. The lower angle dependence makes it easier and more economical to install. LCD displays and models with separate sensor probes are also available.
This manual describes the EE65 series wind speed transmitter used in HVAC air‑conditioning systems. It outlines the operating principle, signal output options, and the benefits of the built‑in temperature sensor for accurate low‑speed measurements.
The document includes technical data, wiring information, mounting instructions, and environmental limits, helping installers configure the device safely and efficiently. This manual is written in Chinese.
