　　压力传感器：稳定性、灵敏度、准确度等关键技术指标

　　压力传感器用于各种应用，从医疗设备到便携式设备。作为一个设计师，在为产品设计选择传感器之前需要考虑一些一般性的规范，包括压力范围、环境条件、包装和输出类型。

　　此外，在选择传感器解决方案时需要考虑几个关键性能规范。在压力传感器的情况下，这包括稳定性和精度要求，这取决于应用程序。此外，设计师应考虑到规格如总误差带（TEB）和集成放大、补偿和校准。所有这些因素都会影响成本和产品性能。

　　一些传感器制造商，如霍尼韦尔传感和控制，开发了产品平台，简化了设计者选择和购买这些设备的方式，考虑了所有这些因素。

　　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.
