Flow-through photometric sensor for the determination of cadmium at toe nanogram per millilitre level
(1993)
A sensor for the determination of cadmium based on retention of the Cdl4″ complex on a QAE Sephadex resin located in the flow-cell of a conventional photometric detector and on subsequent complex displacement reaction with ...
Use of PVDF wire sensors for leakage localization in a fluid-filled pipe
(2020-02-01)
The detection and location of pipeline leakage can be deduced from the time difference between the arrival leak signals measured by sensors placed at the pipe access points on either side of a suspected leak. Progress has ...
Sensor óptico de frentes de onda com quadricélula de dupla eficiência quântica em tecnologia CMOS padrão
(Universidade Federal de Minas GeraisUFMG, 2010-02-15)
This work presents an alternative layout for optical HartmannShack WaveFront Sensor (WFS), which is composed of Position-Sensitive Detectors (PSDs) of the Quad-Cell (QC) type, with two different sensitivity regions (i.e. ...
Analog Linearization of Resistance Temperature Detectors (RTD) Using the Intrinsic Curvature of BandGap Voltage References
(Int Frequency Sensor Assoc-ifsa, 2018-01-01)
Although resistance temperature detectors (RTD) are more linear than thermocouples, they present second and third order non-linearities, and a linear signal processing circuit which converts the voltage on a Pt-100 RTD to ...
