　　壓力傳感器：穩(wěn)定性、靈敏度、準確度等關(guān)鍵技術(shù)指標

　　壓力傳感器用于各種應(yīng)用，從醫(yī)療設(shè)備到便攜式設(shè)備。作為一個設(shè)計師，在為產(chǎn)品設(shè)計選擇傳感器之前需要考慮一些一般性的規(guī)范，包括壓力范圍、環(huán)境條件、包裝和輸出類型。

　　此外，在選擇傳感器解決方案時需要考慮幾個關(guān)鍵性能規(guī)范。在壓力傳感器的情況下，這包括穩(wěn)定性和精度要求，這取決于應(yīng)用程序。此外，設(shè)計師應(yīng)考慮到規(guī)格如總誤差帶（TEB）和集成放大、補償和校準。所有這些因素都會影響成本和產(chǎn)品性能。

　　一些傳感器制造商，如霍尼韋爾傳感和控制，開發(fā)了產(chǎn)品平臺，簡化了設(shè)計者選擇和購買這些設(shè)備的方式，考慮了所有這些因素。

　　As an example， Honeywell‘s TruStability platform， initially launched in 2009， is said to be a highly flexible and configurable solution that provides more than 500，000 user-configured products. This means designers can select from a host of specs including package style， porting options， pressure ranges and types （absolute， differential， or gauge）， supply voltages， and signal output types. In other words， designers can virtually design a customized product by selecting from the standard capabilities within the platform.

　　In addition， the TruStability platform offers fully amplified， compensated， and calibrated over temperature and pressure solutions. This allows designers to eliminate components associated with signal conditioning on the board. And by using a platform approach， suppliers are reusing proven technology， design and processes， reducing both design and purchasing risks.
