Detector, английский
- A general term applied to parts of instruments which are designed to detect ionising radiation . ionising radiations interact with the detector, the detector converts this interaction into a signal which can be amplified and interpreted by other devices.
- Детектор; датчик-измеритель; чувствительный элемент
- A device such a photodiode or photodetector that converts optical energy into electrical energy. they can be made from silicon, germanium, gallium arsenide, indium gallium arsenide or from other semiconductors, depending on the wavelengths to detect. the positive-intrinsic-negative (pin) and the avalanche photodiode (apd) types are used in fiber optics. pin types can be used for analog or digital systems, while apds with their internal amplification can only be used in digital systems
- A device that generates an electrical signal when illuminated by light. the most common fiber-optic detectors are photodiodes.
- Детектор, датчик
Detector (rt), английский
A device that determines the presence of ionizing radiation.
Detector coil, английский
- See sensing coil. detector, xray: sensor, xray.
- См. чувствительную катушку. детектор, рентген: датчик, рентген.
- See coil, sensing.
Detector de mentiras, английский
Una maquina que registra por una aguja en un grafico que varia disturbios emocionales al contestar las preguntas sincera y/o falsamente, como indicado por fluctuaciones en la presion de sangre, la r
Detector element, английский
Чувствительный элемент
Detector log video amplifier, английский
Detector probe, английский
- Adjustable or fixed device through which air and/or tracer is drawn into the leak test instrument and over the sensing element or detector. response is measured in units of pa·m3 · s or std cm3/s. standard flow rate is measured at standard temperature and pressure. also called sampling probe; sniffer probe.
- In leak testing, an adjustable or fixed device through which air and/or tracer gas is drawn into the leak test instrument and over the sensing element or detector. also called a sampling probe or a sniffer probe.
Detector probe test, английский
- Pressure leak test in which the leakage of a component, pressurized with a tracer rich mixture, is detected by scanning the test object with a detector probe connected to an electronic leak detector. leakage tracer gas is pulled from the leak through the probe inlet to the sensing element to cause a visible or audible signal on the indicator of the leak test instrument.
- In leak testing, pressure leak test in which the leakage of a component, pressurized with a tracer rich mixture, is detected by scanning the test object boundary surface with a detector probe connected to an electronic leak detector. leakage tracer gas is pulled from the leak through the probe inlet to the sensing element to cause a visible or audible signal on the indicator of the leak test instrument.
Detector scanning, английский
Detector, detecting device, английский
Scintillation, английский
- With respect to radiation protection , scintillation is the process where by a material will emit light photons when exposed to ionising radiation . the light photons can be measured with a photo-multiplier tube which will multiply the events to produce a
- This term is used to describe the rapid changes in irradiance levels in a cross section of a laser beam produced by atmospheric turbulence.
- The mirrorlike reflections a diamond’s facets make when it is turned while being exposed to light.
- Scintillation is the intense sparkle that comes from a diamond when it moves. black and white sparkles of scintillation show well in flood lit or office lighting environments where fire can be totally absent. under pin point or spot lights fire also adds to scintillation.
- Emission of light of specific frequencies after the absorption of electromagnetic radiation, such as x-rays or gamma rays.
Scintillation (rt), английский
A localized flash of light caused by a particle or photon of ionizing radiation incident on a fluorescent material.
Scintillation counter, английский
- Electronic logger, scintilla¬tion probe
- A device for counting atomic particles by means of tiny flashes of light (scintillations) which the particles produce when they strike certain crystals.
Scintillation probe, английский
An electronic logging device consisting of a scintillation-type gamma ray detecting unit built into a container small enough to be lowered into a borehole.
Scintillator, английский
- A substance which produces a flash of light when struck by radiation
- Brand name of a scintillation counting device.
Scintillator (rt), английский
A substance that emits a localized flash of light when excited by an incident particle or photon of ionizing radiation.

Search unit, английский
- See transducer.
- See transducer. self-coupling transducer: contact transducer that allows testing with a liquid couplant. send/receive transducer: transducer consisting of two piezoelectric elements mounted side by side separated by an acoustic barrier. one element transmits; one receives.7,21
Roof angle, английский
- In a dual-element delay line transducer, the tilt angle by which the transducer elements of the delay line are oriented to direct the beams of the two elements to intersect at a specified zone in the medium. root mean square (rms): statistical measure of the magnitude of a varying quantity, such as current. square root of the mean square of a set of measures, usually a time series. rt: radiographic testing; radiologic testing. s
