Ex-proof Air Flow Velocity Sensor | ATEX Duct Air Flow Speed Transmitter

GE-374-EX Air Flow Velocity Transmitter, adopting the Flame Proof shell for the Explosion Proof Instrument, is designed for air flow measuring, monitoring and controlling. It Measure the flow velocity by Pitot tube with differential pressure sensor, then calculate the flow rater with the Cross sectional area.

Unlike conventional anemometers with temperature sensors or hot film, GE-374-Ex air Velocity sensors operate on the innovative pitot tube principal, which guarantees accuracy at low air velocity, and better performance at high temperature. Additionally, this pitot sensor is less sensitive to dust and dirt than all other anemometer principles.
