AFS air flow sensor units features thermal protection • 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 dimensions and construction Dimensions inches (mm) F G Size A B C D E AFS0001 .984 (25) .197 (5) 2-ø.126 (2-ø3.2) .512 (13) ø.118 (ø3) Size A B C D E F G AFS0002 1.10 (28) .787 (20) .157 (4) 2-ø.126 (2-ø3.2) .394 (10) .118 (3) 1.38 (35) .984 (25) 1.57 (40) H I J K L .217 (5.5) .177 (4.5) ø.118 (ø3) .630 (16) 2-ø.126 (2-ø3.2) Dimensions inches (mm) H J K I 1.12 (28.5) .138 (3.5) .079 (2) .630 (16) L M .787 (20) .197 (ø5) N O P .069 ø.126 R.126 (1.76) (3.2) (R3.2) Q 2-ø.079 (2-ø2.0) Units: inches (mm) AFS0001 G B H I A Red: ±5V White: Output Black: GND F Air-velocity Sensor Thermal Compensation Sensor C E D 16.1 (Cable Length) (410) J K 19.7 (Cable Length) (500) L Control Box AFS0002 G H C J I KL E A B F D 19.1 (Cable Length) Thermal Air-velocity Compensation (485) Sensor Sensor Q P Control Box O N Red: R ±5V White: Output Black: GND M 177.2 (Cable Length) (4500) ordering information New Part # AFS Type – 0001 Type Number 0001 0002 Specifications given herein may be changed at any time without prior notice.
