This paper presents the procedure for determining the upper bound on absolute error (UBAE) for linear variable differential transformer (LVDT) sensors without inter-winding capacitance. This procedure is based on the results of a parametric identification of the sensor, from which the coefficient values of the corresponding transfer function are obtained. The UBAE is then determined by a simulation experiment using dedicated computational software. The error value and the shape of the input signal, which is constrained in magnitude, are determined. The calculations and additional validation of the procedure presented in this article are carried out using the MathCad 5.0 program. As the basis for the proposed procedure, we review issues related to the modelling of LVDT sensors without inter-winding capacitance. The solutions presented here can be used to determine the UBAE, which can then be used to assess the accuracy of these types of sensor and their mutual comparability in terms of dynamic accuracy.

确定 LVDT 传感器绝对误差上限的过程

本文介绍了确定无绕组间电容的线性可变差动变压器 (LVDT) 传感器绝对误差 (UBAE) 上限的程序。该过程基于传感器的参数识别结果，从中获得相应传递函数的系数值。然后使用专用计算软件通过模拟实验确定 UBAE。确定误差值和输入信号的形状（其幅度受到限制）。本文中介绍的过程的计算和附加验证是使用 MathCad 5.0 程序进行的。作为所提出程序的基础，我们回顾了与无绕组间电容的 LVDT 传感器建模相关的问题。这里提出的解决方案可用于确定 UBAE，然后可用于评估这些类型传感器的精度及其在动态精度方面的相互可比性。
