{"product_id":"10-05908","title":"Winter 2-1\/4 Airspeed Indicator 7 Fms 213 Range 0 To 100 Knot 360 Dial","description":"\u003cp\u003e2-1\/4\" and 3-1\/8\" airspeeds are supplied and marked in MPH and knots scales. Indicators feature 360 degrees sweep for easy reading at a glance. All Winter Airspeeds come complete with mounting screws.Airspeed-indicators measure the difference between total pressure and static pressure.The total (or measured) pressure is sensed by a pitot tube positioned at the stagnation point of the airstream and is carried to the airspeed indicator by a hose. A static pressure sensor can also be connected. The measuring element is an open diaphragm unit with excellent elastic properties; hysteresis (differences between advance and return movement) and secondary elastic effects are negligible. The effect total pressure and static pressure acts on the diaphragm, causing a deformation, that is transferred to the pointer by a linkage and gear mechanism. The different operating ranges of the aircraft can be identified by color markings on the airspeed indicator dial. The instruments are insensitive to shock and vibration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 7213\u003c\/p\u003e","brand":"Aircraft Spruce","offers":[{"title":"Default Title","offer_id":54255631728982,"sku":"10-05908","price":1033.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1037\/0164\/3606\/files\/10-03840_da7939dc-b845-4490-b40a-03334c3c53bb.jpg?v=1781873522","url":"https:\/\/www.aircraftpartseurope.com\/products\/10-05908","provider":"Aircraft Parts Europe","version":"1.0","type":"link"}
