OPTOISOLATOR

A coupling device in which a light-emitting diode, energized by the input signal, is optically coupled to a photodetector such as a light-sensitive output diode, transistor, or silicon controlled rectifier. Also known as optical coupler; optical isolator; optically coupled isolator; optocoupler; optoelectronic isolator; photocoupler; photoisolator.

LIGHT-BEAM PICKUP

[ENG ACOUS] A phonograph pickup in which a beam of light is a coupling element of the transducer.

INDUCTIVE COUPLING

Coupling of two circuits by means of the mutual inductance provided by a transformer. Also known as transformer coupling.

INDUCTIVE COUPLER

A mutual inductance that provides electrical coupling between two circuits; used in radio equipment.

IMMERSION SCANNING

Ultrasonic scanning in which the ultrasonic transducer and the object being scanned are both immersed in water or some other liquid that provides good coupling while the transducer is being moved around the object.

COUPLING

A straight connector for shafts or flow lines.

FAST TIME CONSTANT CIRCUIT

A type of coupling circuit, with high pass frequency characteristics used in radar receivers to permit discrimination against received pulses of duration longer than the transmitted pulse. With the fast time constant (FTC) circuit in operation, only the leading edge of an echo having a long time duration is displayed on the radarscope. The use of this circuit tends to reduce saturation of the scope which could be caused by clutter. Also called ANTI-CLUTTER, RAIN, DIFFERENTIATOR

SACRIFICIAL ANODES

Coupling of a more active metal to a structure resulting in a galvanic current flow through the corroding electrolyte.

ELASTOMERIC

A coupling that has resilient materials through which the power is transmitted. They are in some way attached to the coupling halves. They are usually made of rubber, synthetic rubber or plastic materials.

FLANGED COUPLINGS

A type of rigidity coupling used to join shafts of the same or different diameter. Keys are required.
