E
Explosion-proof – Type of protection based on enclosure in which
the parts which can ignite an explosive gas atmosphere are placed
within, and which can withstand the pressure developed during an
internal explosion of an explosive mixture, and which prevents the
transmission of the explosion to the explosive gas atmosphere sur-
rounding the enclosure.
F
Flameproof – Type of protection based on enclosure in which the
parts which can ignite an explosive gas atmosphere are placed
within, and which can withstand the pressure developed during an
internal explosion of an explosive mixture, and which prevents the
transmission of the explosion to the explosive gas atmosphere sur-
rounding the enclosure.
H
HART – a Bidirectional communication protocol that provides data
®
access between intelligent field instruments and host systems.
Level Plus ® Liquid-Level Transmitters - M-Series Model MR Analog Transmitter
Operation and Installation Manual, Part No.: 550720 Revision K (EN) 02/2016
I
Interface – Noun; The measurement of the level of one liquid when
that liquid is below another liquid.
Interface – Adj.; The Software Graphical User Interface (GUI) that
allows the user to access software protocols (HART).
Intrinsic safety – 'Intrinsically safe' - Type of protection based on the
restriction of electrical energy within apparatus of interconnecting
wiring exposed to potentially explosive atmosphere to a level below
that which can cause ignition by either sparking or heating effects.
N
NEMA Type 4X – A product Enclosure intended for indoor or outdoor
use primarily to provide a degree of protection against corrosion,
windblown dust and rain, splashing water, and hose-directed water;
and to be undamaged by the formation of ice on the enclosure. They
are not intended to provide protection against conditions such as
internal condensation or internal icing.
NPT – U.S. standard defining tapered pipe threads used to join pipes
and fittings.
S
Specific Gravity – The density ratio of a liquid to the density of water
at the same conditions.
