Gas flow sensors calculate gas volume in pipes or confined spaces by accounting for temperature and pressure. Various methods are used, including ultrasonic transducers, Coriolis flowmeters, and orifice gauges. Liquid flow sensors are simpler in design. Gas flow sensors must also consider the gas’s composition and use pressure controls and gas chromatograph spectrum analysis. Other […]
Ambient temperature sensors monitor air temperature around machines, engines, and equipment to prevent overheating and damage. They are used in manufacturing plants, automobiles, computer rooms, and can even monitor minimum temperatures. Ambient temperature sensors are devices that measure the air temperature around or near a machine, engine, or other heat-generating equipment. These sensors are intended […]
Air temperature sensors come in various types, including thermocouples, RTDs, infrared sensors, thermometers, and silicon diodes. They are used in various environments to measure temperature changes and regulate fuel flow in automobiles. Each type has its own advantages and limitations. Air temperature sensors include a variety of devices often designed to measure the surrounding ambient […]
Pressure sensors are widely used to monitor fluid pressure in pipes, engines, hydraulic systems, and nature. They work on the principle of piezoresistance and use film resistors, strain gauges, metal alloys, or polycrystalline semiconductors as resistive media. There are various types of pressure sensors, including absolute, gauge, and differential pressure sensors. An intermediate medium is […]
Photoelectric sensors use light to detect objects and measure distance, with applications in manufacturing, transportation, healthcare, and more. Self-contained sensors can be integrated into machines or used for counting and detecting objects. They are also used as safety devices to shut down machines or trigger alarms. Photocells can be designed to operate in different ways, […]
Pain receptors, called nociceptors, are nerve cells that transmit signals to the brain, interpreting them as pain. They respond to internal and external stimuli and release neurotransmitters. A-delta fibers transmit sharp pain, while C-sensory fibers transmit dull pain. Pain medications target second messengers and neurochemical mediators, but only offer temporary relief. A pain receptor is […]
