TELEMETRY.
All Kinds of Contrivances For Detecting
Atmospheric Happenings.
'!Telemetry has become of such i'm
portance that an organization has been
formed known as the Telemeter Com
pany," said gentleman. speak ng of
recent electrical invent ons to report
err. THE system includes series of
instruments operated by electricity, for
indicating and recording temperatures
automatically and continuously. baro
other pressures or forces at distance.
Take, for instance. the telethermOme-
ter. which indicates and records the
temperature of distant points. Each
instrument has maximum and mini
mum bar. If you want to register a
temperature of say 345 degrees and
don't dare 90 beyond $50 degrees, put
the maximum bar at 345, and as soon
as the temperature registers that an
alarm is rung and kept ringing so long
as the temperature remains that high.
1t registers low temperature as well
as b gin, and thus gives at all
times complete knowledge
and control of the temperatures
throughout an entire establishment to
the management of manufacturing or
other industries. An interest ng use to
which the telethermometer is put is in
taking deep-sea temperatures. in its ap-
plicat on to the naval and signal serv-
ice, and for obtaining at all seasons
the temperature in high attitudes and
in uninhabItable places. Other ella ms
for this instrument are its values by in
dicating on the decks of ocean steam
ers the temperature of sea water; as
means of preventing loss and damage
when put in the holds of steamers and
in cars transporting perishable freight,
and preventing spontaneous comDus-
ton. the great danger in the coal
carrying trade. by instantly detecting
and locating the heating of cargoes.
Another of its uses is an automatic fire
alarm, indicating and recording at fire
headquarters the temperature of ware
houses containing valuable merchan-
disc.
What other instruments are there
in the SYSTEM"
There are several. The telebarom-
eter, for indicating and recording bar
ometic pressure at distance. The
value of this instrument in mnes is
great The telemanome-
ter, VIII Oh indicates and records the
pressure in DO Ter at any desired num-
Der OF places. The value of this is es-
pecially great to steam-heating COM
panies. so that they may have the pres
sure of all parts of a steam-distr;-
buting system indicated and re-
corded at central stat on. The tele-
hydrobarometer. indicating and re-
cord ing height of water in a reservoir,
storage pond, river, lake. dam or tank.
Take. for instance. the Improvement of
rivers ::and harbors. - To know &C
curatcly the height of water and of
tides throughout the day for all sea-
sons and in all the districts to be in
fluenced by the proposed improve
ments. is absolutely essential. Thus
the continuous record of the telehy-
is superior to former
methods of getting a record. which
consists in noting the height at stated
intervals. Tbs necess!tates corps of
observers, whose record. when OBJ
tanned, is only partial."
What are these instruments like?"
The transmitter is the portion placed
where the height of the water is meas
ured. This is connected with a receiver
placed in an office. Tne latter indi-
Gates and records the measure taken by
the transmitter by means of electricity.
A japanned iron case ncloses the works
of the transmitting apparatus. The
case has polished brass ring and a
dial measuring ten inches in diameter.
1t is completely protected from both
dust and moisture. A grooved brass
pulley is affixed to the back of the case.
This is revolved in one direction by a
wire attached to float, and IN the OPP
posite direction by means of counter
shaft and weight. Tho pulley. when it
moves. communicate its mot on to the
works in the case a japanned iron
frame strongly supports the entire
case. and 1t is also further protected by
a glass case. Nine and half inches
in diameter is the measurement of
the indicating dial. made for fractional
divisions. For the secondary dial, for
ind eating even feet. the measurement
is two and three-quarters inches in di-
ameter. The secondary dial in the re-
ceiver carries the alarm for ringing q
bell when the height of the water
reaches the limit desired. The record
is made distinct and indelible on a dial
fourteen inches in diameter. Three in
sulated wires connect the transmitters
with the receiver and are operated by
q battery of Prism Leclanche cells.
placed in the office. The transmitter
and receiver NAV be located any dis
lance apart. The battery is such as is in
use bv, all telephone lines, ana requires
no attention. The instruments made
are of two classes. one indicating
heights in feet and inches and the
other in feet and decimals Of & foot"
