Infrared thermometer. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns ...
Sensors are applied for checking the position of the component (detection of weld start and end of weld), for joint tracking and for the adaptation of the process parameters to changes of the joints/grooves. It is possible to use the sensors online (together/at the same time with the welding process) or offline (in a separate working step ...
A surface acoustic wave temperature sensor can be fashioned from a piezoelectric substrate with a relatively high coefficient of thermal expansion in the direction of the length of the device. Temperature sensing and strain sensing can be combined into a single device in order to deliver temperature compensation of the sensing system.
A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, vibration, optical, or potentially other types of sensors, as well as a combination of such sensors. These systems are used by law enforcement, security, military, government offices, schools and ...
Top: IWI Negev Bottom: FN MAG (general purpose machine gun) Czechoslovak 7.62 mm Universal Machine gun Model 1959 A .50 caliber M2 machine gun: John Browning's design has been one of the longest-serving and most successful machine gun designs. A machine gun (MG) is a fully automatic and rifled firearm designed for sustained direct fire with ...
Electronic firing refers to the use of an electric current to fire a cartridge instead of a centerfire primer or rimfire primer. [ 1] In modern firearm designs, a firing pin and primer are used to ignite the propellant in the cartridge which propels the bullet forward. The firing pin must travel a short distance, creating a short delay between ...
The PKP Pecheneg ( P ulemyot K alashnikova P ekhotny "Pecheneg", Russian: Печенег) [ 8][ 9] is a Russian 7.62×54mmR general-purpose machine gun. [ 4] It is a further development and modification of the PK machine gun (PKM). [ 10] It is said to be more accurate than all its predecessors due to a heavier, removable, partially forced-air ...
M1895 Colt–Browning machine gun. Colt–Browning M1895/14 machine gun in 7mm Mauser caliber, possibly used in the Mexican Revolution. The Colt–Browning M1895, nicknamed "potato digger" because of its unusual operating mechanism, is an air-cooled, belt-fed, gas-operated machine gun that fires from a closed bolt with a cyclic rate of 450 ...
