air flow sensor units
• The platinum thin-film thermal sensor realizes
high and long-term stability
• The small platinum thin-film thermal sensor and an
even temperature differential operating circuit ensure
a quick response
• The built-in temperature compensation circuit assures
correct values regardless of air temperature. The air
velocity sensor and air velocity temperature compensation
sensor are sensors with the same characteristics to
enable correct temperature compensation
• Products have no rotating mechanism and are resistant
to vibrations
• Products are compact and light, and are easy to be
installed in equipment
