Corn Moisture Measurement using a Capacitive Sensor
Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...
متن کاملCapacitive sensor for relative angle measurement
Based on a capacitive angle and angular rate sensor, a sensor measuring the relative angle between two rotating shafts has been developed. Two rotatable electrodes are placed between two sensor plates. The relative angle between the two rotors and the absolute position of the rotor blades are calculated from measurements of the capacitive coupling between different transmitting stator segments ...
متن کاملAspheric Surface Measurement Using Capacitive Sensors
This paper proposes a new method for the measurement of spherical coordinates by using capacitive sensors as a non-contact probe solution of measurement of aspheric surfaces. The measurement of the average effect of the capacitive probe and the influence of capacitive probe tilting were studied with respect to an eccentric spherical surface. Based on the tested characteristic curve of the avera...
متن کاملPervasive Activity Detection with Capacitive Sensing
This paper presents a toolkit for realizing capacitive sensing applications for human-computer interaction in pervasive computing systems. We describe the CapSenseToolkit, a complete toolkit for prototyping and implementing systems for detecting presence of humans and objects and for integrating 3D interaction with everyday objects. This allows to acquire data and develop sophisticated algorith...
متن کاملMeasurement Error Estimation for Capacitive Voltage Transformer by Insulation Parameters
Measurement errors of a capacitive voltage transformer (CVT) are relevant to its equivalent parameters for which its capacitive divider contributes the most. In daily operation, dielectric aging, moisture, dielectric breakdown, etc., it will exert mixing effects on a capacitive divider’s insulation characteristics, leading to fluctuation in equivalent parameters which result in the measurement ...
