style="text-indent:25px">電子壓力傳感器是使用較為普遍的一種傳感器。傳統(tǒng)的壓力傳感器以機(jī)械結(jié)構(gòu)型的器件為主，以彈性元件的形變指示壓力，但這種結(jié)構(gòu)尺寸大、質(zhì)量重，不能提供電學(xué)輸出。隨著半導(dǎo)體技術(shù)的發(fā)展，半導(dǎo)體壓力傳感器也應(yīng)運(yùn)而生。其特點是體積小、質(zhì)量輕、準(zhǔn)確度高、溫度特性好。特別是隨著MEMS技術(shù)的發(fā)展，半導(dǎo)體傳感器向著微型化發(fā)展，而且其功耗小、可靠性高。在選擇電子壓力傳感器的時候我們要考慮他的綜合精度，而壓力傳感器的精度受哪些方面的影響呢?其實造成傳感器誤差的因素有很多，我們注意說無法避免的誤差。電子壓力開關(guān)控制器量程的選擇很關(guān)鍵。電子式電壓傳感器售價</p><p
