| AFS air flow sensor units features * 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 Size AFS0001 A .984 (25) B .197 (5) C .079-o.126 (2-o3.2) D .512 (13) E o.118 (o3) Dimensions inches (mm) F G .984 (25) 1.57 (40) H .217 (5.5) I .177 (4.5) J o.118 (o3) K .630 (16) L .079-o.126 (2-o3.2) Size AFS0002 A 1.10 (28) B .787 (20) C D E F .118 (3) G 1.38 (35) Dimensions inches (mm) H I J K 1.12 (28.5) .138 (3.5) .079 (2) .630 (16) L .787 (20) M .197 (o5) N O P Q .157 .079-o.126 .394 (4) (2-o3.2) (10) .069 o.126 R.126 .079-o.126 (1.76) (3.2) (R3.2) (2-o3.2) AFS0001 A B G H I AFS0002 C F A B E G H J I KL M D Thermal Air-velocity Compensation Sensor Sensor Q Control Box P O N F Air-velocity Sensor Thermal Compensation Sensor C D E J Control Box L K ordering information New Part # AFS Type 0001 Type Number 0001 0002 Specifications given herein may be changed at any time without prior notice.
