The EE65 series of air velocity transmitters is the ideal choice for accurate ventilation control applications. It is based on an innovative thermal film anemometer. The thin film sensor from IFM guarantees high accuracy even at low air velocities, which cannot be achieved with conventional anemometers using temperature sensors or NTC.
The EE65 series is a wind‑speed transmitter designed for precise ventilation control in HVAC and process environment applications. It uses a thin‑film sensor that maintains high accuracy even at low air speeds and is less sensitive to dust and dirt.
The manual covers power requirements, electrical connections, cable specifications, protection ratings, measurement ranges, output signals, temperature limits, and installation options such as wall‑mount, duct‑mount, and split‑probe configurations. This manual is written in Chinese.
