effect of inductive coil shape on sensing performance of Linear Displacement sensor using thin inductive coil and pattern guide
Sensors, 2011Co-Authors: Norhisam Misron, Norrimah Abdullah, Loo Qian Ying, R N Firdaus, Nashiren Farzilah Mailah, Hiroyuki WakiwakaAbstract:This paper discusses the effect of inductive coil shape on the sensing performance of a Linear Displacement sensor. The Linear Displacement sensor consists of a thin type inductive coil with a thin pattern guide, thus being suitable for tiny space applications. The position can be detected by measuring the inductance of the inductive coil. At each position due to the change in inductive coil area facing the pattern guide the value of inductance is different. Therefore, the objective of this research is to study various inductive coil pattern shapes and to propose the pattern that can achieve good sensing performance. Various shapes of meander, triangular type meander, square and circle shape with different turn number of inductive coils are examined in this study. The inductance is measured with the sensor sensitivity and Linearity as a performance evaluation parameter of the sensor. In conclusion, each inductive coil shape has its own advantages and disadvantages. For instance, the circle shape inductive coil produces high sensitivity with a low Linearity response. Meanwhile, the square shape inductive coil has a medium sensitivity with higher Linearity.

Basic characteristic of Linear Displacement sensor using meander coil and pattern guide
2008Co-Authors: Norhisam Misron, Norrimah Abdullah, Rahman Wagiran, Roslina Mohd Sidek, Norman Mariun, Hiroyuki WakiwakaAbstract:Linear Displacement sensor is used to detect the actual Displacement of the moving objects in the Linear DC Motor (LDM) (Wakiwaka et al, 1996). The accuracy of the detection is very important to make sure the production process operate properly. The Displacement sensor based on the inductive concepts has been developed. It is composed of the sensor head and pattern guide. The combination of the sensor head and pattern guide is important to get the high accuracy of the positioning. Sensor head is made from copper material while pattern guide is made from soft iron SS400. The Displacement of pattern effects to the output voltage for various input frequency and exciting voltage has been observed and discussed in this paper. From the results obtained, output voltage increases as the input frequency and exciting voltage increases. In term of hysteresis and Linearity, input frequency 20kHz and exciting voltage 1.0 volt is the best performance of sensor.
