PURPOSE:To enable mechanical and electronic inspection of a spray pattern by disposing many temp.-electric energy converting elements and detecting the temp. change by cooling with a liquid spray. CONSTITUTION:Cooling water 5 is sprayed by spray nozzles 4. The many temp.- electric energy converting elements 6 are exposed from a spray pattern detector 2. A thermistor is kept heated to a high temp. by a constant current source 8. The change of the resistance value with a temp. change of the thermistor as a result of cooling with the spray water is scanned and read by an electronic scanning circuit 9 and is stored in a memory 12 after analog-to-digital conversion in an analog-to-digital converter 11. The detector 2 moves and the information on the spray pattern by each nozzle 4 is taken therein and is stored into a memory 12. The information on the spray pattern is fetched to a monitor television or computer, etc. |
