WS-25 Air Velocity Transmitter
Product Description
WS-25 Air Velocity Transmitter offers high accuracy at a surprisingly low price. And it has very sensitive responsivity for air velocities,even for the lowest air velocities(close to 0). WS-25 Air Velocity Transmitter with several output signal for user selectable .
We design several mounting way structure according different applications.，User can choose different type accoding the requirment and fix the Transmitter in the location where airflow is measured to get a stable signa. We also provide different length probe and cable for customers to choose.
