Air Velocity Transmitters
The Air Velocity Transmitters and Switches are designed for the exact measurement of air velocity (Mass Flow). Utilizing thin film thermal sensor elements and hot wire anemometer technology, these Air Velocity Transmitters and Switches measure air velocity with no wear to the sensor element. This technology affords excellent accuracy down to "0" meters/second (feet/min), is almost non-directional and offers good resistance to pollutants.
The Air Velocity / Temperature Transmitter Series EE75 has an exceptional high accuracy, scalable ranges and outputs and can be programmed to calculate the volume flow in ft3/min or m3/hr.
The HVAC Air Velocity transmitters and switches are low-cost but very durable devices with ranges as low as 0 - 1 m/s (0 - 200 ft/min) up to 0 - 20 m/s (0 - 4000 ft/min). Analogue outputs are 4 - 20 mA and 0 - 10 Vdc.
