{"product_id":"7-100-20","title":"UMA 7-100-20 Manifold Pressure Indicator","description":"\u003cp\u003eUMA 7-100-20 is a 2¼ in (57 mm) mechanical manifold pressure indicator with a 10–35 inHg range and UMA’s standard black-and-white dial markings. The instrument has a single diaphragm and a cast aluminum case, and weighs 4.7 oz (about 133 g).\u003c\/p\u003e\u003cp\u003eThe indicator shows the absolute pressure in the engine intake manifold; together with engine rpm, it indicates the power the engine produces. Port “V” connects through a 1\/8 NPT fitting to a line from the intake manifold or from a cylinder port intended for this connection. UMA specifies a loop in the line with a drain valve at the lowest point, drained occasionally. The bezel is 2.38 in square with four mounting holes on a 2.625 in circle, and the case extends 1.95 in behind the bezel. Special range markings and internal lighting are available from UMA on request. UMA lists black-and-white versions with 10–50 and 10–40 inHg as 7-100-10 and 7-100-30.\u003c\/p\u003e\u003cp\u003eUMA states that the 7-100-20 is not FAA certified and was not manufactured under a PMA or TSO authorization; it belongs to UMA’s engine instrument range for experimental aircraft. The engine and aircraft manufacturers’ recommendations apply to all connections. Fit depends on the engine type.\u003c\/p\u003e","brand":"UMA Instruments","offers":[{"title":"Default Title","offer_id":58183748321611,"sku":"7-100-20","price":4589.3,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1055\/1063\/3803\/files\/161-7-100-20.jpg?v=1791814684","url":"https:\/\/shop.airteam.eu\/products\/7-100-20","provider":"AIR TEAM","version":"1.0","type":"link"}
