Cutaway view of an LVDT. Current is driven through the primary coil at A, causing an induction current to be generated through the secondary coils at B.. The linear variable differential transformer (LVDT) – also called linear variable displacement transformer, [1] linear variable displacement transducer, [2] or simply differential transformer [3] – is a type of electrical transformer [4 ...
MDT – modular formation dynamic tester, a tool used to get formation pressure in the hole (not borehole pressure which the PWD does). MDT could be run on Wireline or on the Drill Pipe; MDR – mud damage removal (acid bullheading) MEA – monoethanolamine; MEG – monoethylene glycol; MEIC – Mechanical Electrical Instrumentation Commission
An LVDT (Linear Variable Differential Transformer) Variable Area Rotameter, is a meter designed to measure the flow rate of a fluid or gas. [citation needed]
A rotary variable differential transformer (RVDT) is a type of electrical transformer used for measuring angular displacement.The transformer has a rotor which can be turned by an external force.
The linear variable differential transformer (LVDT) a type of electrical transformer used for measuring linear displacement. The transformer has three solenoidal coils placed end-to-end around a tube. The center coil is the primary, and the two outer coils are the secondaries.
TVS diode as array. A transient-voltage-suppression diode may be either unidirectional or bidirectional. A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode, but is made and tested to handle very large peak currents.
Symbol Name Meaning SI unit of measure nabla dot : the divergence operator often pronounced "del dot" per meter (m −1) : nabla cross : the curl operator often pronounced "del cross"
A – adele ring or algebraic numbers. a.a.s. – asymptotically almost surely. AC – Axiom of Choice, [1] or set of absolutely continuous functions. a.c. – absolutely continuous.
