Transmission distance

On the 4a graph the spectrum of the signal for transmission distance of 8 mm in the area of the weld is depicted, the corresponding scheme of location of the probe is shown in Figure 3 a.

The value i// = (S2— S, )/S1( where S is av (50%) transmission distance in air (gap) of initiation of deton and S2 is av (50%) transmission distance of combstn, is taken as a basis for evaluation of the combstn tendency. The transmission distance was detd by expln of a composite cartridge consisting of active and passive segments with air gaps between them... 

Transmission of detonation is different for air gaps and dirt gaps. Transmission distances are much greater in v wet soil than in dry soil. In the open, distances (across air gaps) are shorter than in bore holes. In the open, the medium on which the cartridges are laid also... 

Type I—dynamites and rock explosives. The chief ingredients of the latter are ammonium nitrate, nitroglycerine and TNT. Their rate of detonation at a density of 1.1 is about 3800m/sec, their transmission distance 6 cm.

The physical wiring typically used is the plant standard twisted-pair wiring Tor 4- to 20-mA instrumentation. Because of the networking capability of the bus, more than one device can be supported on a single pair of wires, and thus wiring requirements are reduced. Compared to a host level bus such as Ethernet, field buses exhibit slower communication rates, have longer transmission distance capability (1 to 2 km), use standard two-wire installation, are capable of multidrop busing, can support bus-powered devices, do not have redundant modes of bus operation, and are available for intrinsically safe installations. Devices on the field bus network may be either powered by the bus itself or powered separately. 

The resulting transmission distance is reported as the coefficient of detonation transmission (Koeffizient der Detonationsiibertragung coefficient de transmission de la detonation, C. T. D.) and should be the arithmetic mean of three positive and negative results obtained in successive trials.

The standard parallel port is a parallel port that only transmits data OUT of the computer. It cannot receive data (except for a single wire carrying a Ready signal). This is the parallel port that came with the original IBM PC, XT, and AT. This port can transmit data at 150KB/second and is commonly used to transmit data to printers. This technology also has a maximum transmission distance of 10 feet. 

Each of these six levels has a maximum transmission distance of 100 meters. 

Tlie transmission distance of picric acid charges was examined by Burlot [22]. This is however outside the scope of the present book. Also the method of determining the transmission detonation througli an inert solid medium, such as a number of card-boards ( card-gap test ) [116, 117], cellulose acetate [121, 122] or Plexiglas layer is discussed in the literature on the theory of detonation, for example [34].

RCLEDs are now commercial products that are manufactured by the millions per year. Primary applications are in signage and communication. The devices are particularly well suited for plastic optical fiber systems. The directed emission pattern improves LED-fiber coupling efficiency The narrow emission line reduces material and chromatic dispersion effects. As a result, RCLEDs enable longer transmission distances and simultaneously higher data rates. 

Nodic Company s monohthic RF transceiver chip nRF905 is chose as the wireless communication chip which work in 433/868/915 MHz (SUN Peng 2008), and the transition time between channels is less than 650 ps. It works with 4 modes, and the Shock Burst mode can automatically produce lead code and CRC check code. Current consumption is very low, when transmission power is -10 dBm and the emission current is about 11 mA and receiving current is 12.5 mA. Single-ended whip antenna can be used and the maximum transmission power is lOdBm. In the open area, the furthest transmission distance can reach more than 1 km.
