Vehicle Crash Sensors: Remote Acceleration Sensor
网页According to Koenning, M and Heger, T (2009), a typical passive safety sensor like acceleration sensor determines the extent of vehicle crash based on impact velocity, type of crash such as offset crash, full frontal crash, and mass of the crash participant. The key role of the acceleration sensor as discussed by Pack, R et al (2005) in a ...
Automotive Airbag Sensors
网页2012年7月27日 · 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 ...
What is Geophone? - AZoSensors
网页Jun 25 2013. A geophone is a ground motion transducer that has been used by geophysicists and seismologists to convert ground movement into voltage. Any deviation in this measured voltage from the base line is regarded as seismic response, which is used for analyzing the earth’s structure. Resonance frequency is the key factor in a geophone ...
What is a Selsyn? - AZoSensors
网页2013年9月30日 · Selsyn or synchro is an electro-mechanical device used for the easy and precise transmission of angular data between two or more remote points. The readings may be provided in terms of mechanical position or as an electrical signal. Selsyn is a portmanteau of ‘self-synchronous’. In the broad sense, selsyn systems can …
What is a Breathalyzer? - AZoSensors
网页2012年6月22日 · The most standard alcohol breath test is performed using a breathalyzer. This device is made up of two vials composed of a photocell indicator and a series of chemicals that work together to calculate blood alcohol concentration (BAC). A mouthpiece is attached to the breathalyzer, that allows the suspect to blow into the device.
What are Encoder Sensors?
网页Kalabi Yau / Shutterstock. Encoder sensors are a type of mechanical motion sensor that create a digital signal from a motion. It is an electro-mechanical device that provides users (commonly those in a motion control capacity) with information on position, velocity and direction. There are two main types of encoder: linear and rotary.
How Does a Fuel Level Sensor Work?
网页2019年3月26日 · 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 ...
Accelerator Pedal Position Sensors vs. Throttle Position Sensors
网页The 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 ...
How Does a Water Quality Sensor Work?
网页2018年11月2日 · A water quality monitoring system can supply crucial data to researchers, operators and engineers for use in laboratory research, quality control, and hydraulic model calibration by tracking shifts in the quality of the water source over time. Water quality sensors can be the eyes and ears of system operators, offering real-time actionable data ...
Motion Detectors - Working Principles and Applications
网页Motion 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 ...
