摘要: A pitot tube (10) produces pressure when a marine craft moves through water. The produced in the is applied to monolithic transducer (14) that includes piezoresistive integrated circuit for producing an output voltage proportional from (10). of processed op amp (28) and converter (40) produce (E o ) linearly speed craft. This volt meter (62) scaled indicate distance per unit time.
