E+E Elektronik’s new miniature air velocity transmitters, series EE575 and EE576, allow accurate measurements of flow in air and gases. The EE575 measures velocities up to 20 m/s, while EE576 is designed for the measurement of low flows up to 2 m/s. Applications for these transmitters are found in HVAC systems, handling and controls for intake and exhaust of air and laminar flow monitoring.
Equipped with a newly developed sensor head and utilising the proven E+E hot-film element, already tested millions of times in the automotive industry, these transmitters are less sensitive to dust and dirt than conventional hot-wire elements.
The design with a probe length of 150 mm and the integrated electronics make the units compact, allowing for use in applications where mounting space is limited. The alignment strip along the side of the probe and the matching mounting flange secures the positioning of the sensor and the immersion depth of the probe is infinitely variable. That saves time and prevents incorrect installation.
The series can be operated from a 10-29 VDC supply and provides standardised linear output signals of 0-5 or 0-10 V. With a temperature range of -20 to 60°C and electrical connection through a 0,5 m or 2 m long fixed cable, the series EE575 and EE576 ensures high application and mounting flexibility.
