Accelerator Pedal Position Sensors vs. Throttle Position Sensors
WEBThe accelerator pedal position sensor is also involved in converting the acceleration movement when the pedal is pressed into an electronic signal, which then initiates throttle body control either as opening or closing movements. The accelerator position information is transferred to the throttle actuator control (TAC) module and the ...
Automotive Airbag Sensors
WEBJul 27, 2012 · The sensor is positioned inside the engine and a similar safety sensor is located inside the passenger zone of the vehicle. This safety sensor is required to measure the intensity of the collision to determine whether the impact is over a certain threshold to justify the release of an airbag. Both types of sensors (termed inertia sensors) work ...
Trends Towards Single-Chip Optical and Magnetic Encoder iCs
WEBMar 10, 2014 · In our definition, a single-chip encoder includes integrated magnetic or optical sensor functions, signal conditioning, analog-to-digital conversion, respective interpolation, and a driver to interface with the motion controller. By this approach the complete encoder function comes available in a small …
The Basic Principles of Vibrometry - AZoSensors
WEBNov 21, 2016 · The Basic Principles of Vibrometry. If a wave is reflected by a moving object and detected by a measurement system (as is the case with the LDV), the wave’s measured frequency shift can be expressed as follows: f D = 2•v/λ. Where, v is the velocity of the object and λ is the wavelength of the emitted wave. An object’s velocity can be ...
What is Oxidation Reduction Potential and How Do ORP Sensors …
WEBNov 2, 2023 · Sponsored by Hamilton Process Analytics Reviewed by Aimee Molineux Nov 2 2023. Oxidation Reduction Potential (ORP) measures the net voltage potential of excess oxidizers or reducers in a liquid. As it is a less common measurement, it can often be misunderstood. It is also referred to as "Redox" since the sensor measures redox reactions.
What is an Actinometer? - AZoSensors
WEBSep 3, 2020 · An actinometer is a device that is used to measure the intensity of solar radiation. It involves a chemistry technique that determines the number of photons by measuring the rate of change of photo-induced responses in a chemical system. The actinometer was invented by John Herschel in 1825. …
How Does a Fuel Level Sensor Work?
WEBMar 26, 2019 · Fuel level sensors allow vehicle operators to monitor fuel consumption and determine when to refill the tank. A fuel level sensor consists of two main components: the sensing system itself (also known as the sender) and the indicator (also commonly referred to as the gauge). Fuel level sensors work by measuring the voltage across a variable ...
Motion Detectors - Working Principles and Applications
WEBMotion detectors are primarily used for detecting moving objects (especially people), and gathering data regarding position, acceleration, and velocity. Motion detectors most commonly use an infrared detection sensor, which can be incorporated into various devices found around us. This sensor provides data about motion, using which the device ...
Debunking Myths Surrounding Ultrasonic Sensor Reliability
WEBApr 29, 2021 · Sponsored by Massa Products Corp. Apr 29 2021. A common assumption among a majority of the end-users of sensors is that solids can be reliably tracked only by using a costly technology, like radar, or by derating the distance of an ultrasonic sensor by 50%. As a matter of fact, this assumption has been effectively accepted by …
Olfactometer for the Measurement of Ambient Odor Concentrations
WEBSep 3, 2020 · On the present market, there are different types of olfactometers, among which the following two are most common: 'Yes/no' olfactometers: from the sniffing port odorless air or air with odor comes out alternatively and the panelist shall indicate on the evaluation card if he/she detects the odor or not. 'Forced-choice' olfactometers: includes ...
