Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
The tube checker is the second-simplest of all tube testers after filament continuity testing. Tubes are used as a low power rectifier, with all elements other than filament connections connected together as the anode, at a fraction of its normal emission. By mistake referred to sometimes as Emission Tester because they are a crude measure of ...
RTD may refer to: Science and technology. Real-time data; Residence time distribution; Resonant-tunneling diode; Round-trip delay time, in telecommunications;
A vacuum fluorescent display (VFD) is a display device once commonly used on consumer electronics equipment such as video cassette recorders, car radios, and microwave ovens. A VFD operates on the principle of cathodoluminescence , roughly similar to a cathode-ray tube , but operating at much lower voltages.
Typical passive oscilloscope probe being used to test an integrated circuit. A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
And now my car is sputtering so bad, I barely made it to work." Hannah Crawford decided to try out the viral "Christmas gas" prank on her husband and captured the humorous moment on video.
Washington Commanders running back Austin Ekeler was placed on injured reserve this past weekend after he sustained his second concussion in a span of just two months.
The earliest vacuum tubes evolved from incandescent light bulbs, containing a filament sealed in an evacuated glass envelope. When hot, the filament in a vacuum tube (a cathode) releases electrons into the vacuum, a process called thermionic emission. This can produce a controllable unidirectional current though the vacuum known as the Edison ...
