Acquired by Det-Tronics (Detector Electronics Corporation) in 1992, the detector operated in the 3.4 μm region with a powerful incandescent source and a mechanical chopper. It did not achieve large volume sales, mainly because of cost and doubts about long-term reliability with moving parts.
A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.
ecu.test automates the control of the whole test environment and supports a broad range of test tools. Various abstraction layers for measured quantities allow its application on different testing levels, e.g. within the context of model in the loop, software in the loop and hardware in the loop as well as in real systems (vehicle and driver in the loop).
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
User's guide for a Dulcitone keyboard. A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images.
Since incandescent lamps were used, a lamp test button was always provided to allow early detection of failed lamps. Modern electronic distributed control systems usually require less wiring since the process signals can be monitored within the control system, and the engraved windows are replaced by alphanumeric displays on a computer monitor.
Originally named Tex-Tronics, Inc., Andrews changed the name to TTI, Inc., in 1973 to avoid a legal dispute involving another company with a similar name. Founded to serve aerospace and defense equipment manufacturers, the company’s customers now include manufacturers in the transportation, industrial, medical, and communications sectors. [1]
A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed. Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared.
