Product Overview
YGM212 air speed transmitter is an ideal choice for measuring wind speed in the field of precise ventilation control, mainly used in fire protection systems, commercial buildings and BA systems in energy-saving buildings. It takes the innovative hot film anemometer as its working principle, and the YGM film sensing element used in it still maintains high accuracy at low wind speed, which has more obvious technical advantages compared with the traditional anemometer using general temperature sensor technology or NTC bead thermistor technology. The sensitivity of the sensor developed by YGM to dust and dirt is relatively low, so that the measurement is more reliable and the maintenance cost is lower. Even so, the transmitter still has certain requirements for air cleanliness.
YGM212 can be equipped with LCD display and buttons to directly set the alarm range, which is easy to operate.
YGM212 has switching value output function.
