STRAIN GAUGE SENSOR OF MASS MEASUREMENT USING A BRASS CANTILEVER

A Rotating Cantilever Beam for Dynamic Strain Measurement and Vibration Analysis Based on Fbg Sensor

Strain measurement and vibration analysis of a rotating blade are critical for the progress in improvements of the performance of machines. Since traditional sensors and measurement methods have difficulty measuring the rotor blade’s dynamic strain and vibration, the search for new measurement methods has become an urgent task in rotor machine monitoring and diagnosis. This paper presents a new...

Direct Torque Measurement of Hermetic Rotary Compressors Using Strain Gauge

Strain Measurement of Carbon Composites Using Advanced Sensor Technology

This paper reports the sensor integration method into carbon composites for the development of Structural Health Monitoring (SHM). Early detection and long term monitoring of the specific properties of composites will improve the security and prolong the time of service 1 . The core function of SHM is the damage detection and identification at elevated temperatures, over loads and corrosion. Va...

Measurement of Temperature, Humidity and Strain Variation Using Bragg Sensor

Measurement and monitoring of temperature, humidity and strain variation are very requested in great fields and areas such as structural health monitoring (SHM) systems. Currently, the use of fiber Bragg grating sensors (FBGS) is very recommended in SHM systems due to the specifications of these sensors. In this paper, we present the theory of Bragg sensor, therefore we try to measure the effic...

A mechanical micro molecular mass sensor

One of the bio-sensing mechanisms is mechanical. Rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. This study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on Silicon wafer, with the ...
