Condenser plugging up alarm device of reefer on-board device

摘要

(57) Abstract Objective As for this device to be able install easily even from after,ru way, alarm device data of self normal wind velocity automatic settingThe plugging up alarm device of the condenser of the mode which it does is offered denselyWith it is something which is made purpose. Constitution When there is no storage of the normal wind velocity data, configuration suitsuCalling the start signal of wind velocity measurement treatment with chi 5, wind velocity measuringMeasuring the even wind velocity data with fixed means, 6 storing that dataThe data storage means 4 which it does and the normal wind velocity data being storedWhen being, decision target wind velocity is measured with aforementioned wind velocity measurement means 6,The data storage means 4 which store that data of the te and aforementioned storageThe data and normal wind velocity of the decision target wind velocity which is stored in means 4Comparing the data, the operation treatment which decides abnormality and announces officially alarmBecause it possesses with means 7, our the alarm device is not armamentIt can install easily even in the dynamic sale machine.
