设计一种海洋调查用的深度传感器,不仅要求精密准确和稳定可靠,而且要数据显示线性化好。实现线性化一般采用两种途径:一种办法是将传感器的非线性误差通过补偿措施来实现,另一种办法是直接通过弹性元件的特殊设计来实现。我们在本刊第一期技术讨论中已介绍了一种通过补偿措施实现线性化的弹簧管式深度传感器;本文将介绍一种从弹性元件的特殊设计来达到线性化的深度传感器。 Designing a depth sensor for marine surveying not only requires precision, accuracy, reliability, but also linearity of the data. There are generally two ways to achieve linearization: One way is to compensate for the nonlinear error of the sensor, and the other is directly through the special design of the elastic element. We have introduced a spring-tube depth sensor that is linearized by means of compensation in a technical discussion in our issue. This article will introduce a depth sensor that can be linearized from the special design of elastic elements.
