Dragging detector
| Глоссарий в железнодорожной технике |
A device designed to alert a railway control centre that a train has become derailed or a part of the train is dragging on the right of way. normally consists of a bar placed across the four-foot (between the rails) which will be broken if struck. often used on remote heavy haul freight lines where it is difficult for the crew to detect a mishap of this sort.

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

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

Draggable, английский
Перетаскиваемый (по экрану)
Dragged, английский
Said of an exposed surface over which a drag or comb has been pulled or worked to produce a textured surface.
Dragged. combed-finish tile tile whose face surfaces are altered by more or less parallel scratches in manufacture to give increased bond for mortar, plaster, or stucco., английский
Dragging, английский
- An old word for dredging.
- Перемещение; буксировка; перетаскивание
Dragging beam, английский
Dragging on her, английский
Said of a vessel in chase, or rounding a point, when she is obliged to carry more canvas to a fresh wind than she otherwise would.
Dragging piece, английский

Anticreeper (us), английский
A device firmly attached to the base of a rail and bearing against a crosstie (sleeper), to keep the rail from moving longitudinally under traffic. (uk: rail anchor.)uos
Driving van trailer (dvt), английский
A development of the driving trailer which was introduced in the uk following an accident at polmadie in scotland when a diesel multiple unit struck a cow and derailed, causing the deaths of several people. it is now forbidden in the uk to carry passengers in the leading vehicle of a train operating at speeds over 160 km/h, hence the introduction of the dvt.
