概述

我们目前的加速度和速度传感工具的发展始于 速度传感器 that offered a self-generating moving-coil design used by geologists to measure movement in the earth’s crust. 今天,我们仍然用“地震”来指代它们的起源.

这些早期的传感器被坚固耐用的固态加速度计所取代, later ushering in today’s integrated accelerometers that deploy signal processing circuitry for output signals using velocity rather than acceleration.

我们的 experience and expertise developed over decades offer a selection of first-rate 套管-mounted accelerometers and 速度传感器 with a variety of models for specific applications.
