Air Velocity Transmitter

详情

 Features
● Based on thermal measurement principal, using innovation, advanced, sensitive hot film sensor, strong pollution tolerance, low
airflow angle dependence, easy to install and maintain
● Sensor without moving mechanical components to provide accurate, reliable, sensitive and long-term detect,
wide working temperature range and real-time temperature compensation
● Digital technology applied, ensure the output signal linear and accuracy
● Output with over voltage and reverse polarity protection, high reliability and interference capability
● Multiple output optional, optional relay output for alarm or control
● Field jumpers selection air velocity range 0~5/*0/*5/*0m/s
● MMI operation panel can configure various functions of parameter setting, modification and calibration
Optional MMI operation panel： Including LCD, integrated with function keys, can be ordered and installed in field separately.
See details on MMI product.
