The E+E EE671 Air Flow Transmitter is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology. The EE671 operates on the hot-film anemometer principle and ensures high accuracy and reproducibility as well as long-term stability and outstanding resistance to pollutants.

The EE671 is available with fix installed cable or with plug connection. The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and correct positioning in the air flow. The flange enables the immersion depth to be infinitely variable.

Applications for the EE671 include:

  • Heating and ventilation systems
  • Flow monitoring and control
  • Inlet air monitoring in ovens

Application Notes

Here's how some of our customers used this product.

Cooling Tower Fan

The Background: Our customer is a large industrial facility that uses a large cooling tower to remove excess heat from critical machinery. The customer seeks a way to ensure the motor at the bottom of the tower has a sufficient supply of air to keep it cool.

The Problem: The main circulating fan is air-cooled so maintaining enough air flow around the cooling fins is critical to keep the fan motor from overheating.

The Solution: We recommended the E+E EE671 Air Flow Transmitter which is ideal for this application primarily because of its compact design and resistance to contamination. The anemometer will be connected with several other temperature sensors to create a real-time remote monitoring system that feeds all of the data to “the cloud” so the company can get instant feedback as to how effective the cooling system is for the motors.
