Based on piezoelectric sensor

design a measurement equipment of deviation angle for lateral liquefied cargo replenishment between two ships. Firstly

build a theoretical model for liquid replenishment; secondly

carry out mathematical analysis and parameter design to meet functionality requirement; finally

through design of circuit system

realize deviation angel measurement and display between two ships. Experimental result show that deviation angel measurement equipment based on piezoelectric sensor can meet the functionality requirement with0. 1° precision

which measurement range- 30°

+ 30°

working temperature- 25

+ 65℃

environment humidity below 95 % RH and meanwhile it is proved that its temperature reliab

ility

and anti-interference ability are high and repeatability is good.
