TELEMETRY,

''Telemetry has become of such inn
portance that an organization has been
formed known as the Telemeter Com
pany," said a gentleman. speak ne of
recent electrical inventions to a report
er. The system includes a series Of
Instruments operated by electricity, for
indicating and recording temperatures
automatically and continuously. baro
metric, steam. water. electrical and all
other preSsures or forces at a 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 $40 degrees and
don't dare 60 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 gh, and thus gives at all
times complete knowledge
and control of the temperatures
throughout an entire establishment to
the management of manufacturing or
which the telethermometer is put is in
taking deep-sea temperatures. in its ap-
plicaton to the naval and signal serv-
ice, and for obtaining at all seasons
the temperature in high attitudes and
in uninhabtable places. Other claims
for this instrument are its values by in
dicaling 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 comous-
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 mines is
particularly great. The telemanome-
ter which indicates and records the
pressure in boiler at any desired mum.
Der OF places. TIT value of this is es-
pecially great to ,m-heating COM
panies. so that theI ~ have the pres
sure of all parts steam-distri-
buting system id ated and re-
corded at a central ton. The tele-
hydrobarometer. Locating and re-
cording height of H--er in a reservoir,
storage pond, river, lake, dam or tank.
Take. for instance, the improvement of
rivers land harbors. ~ To know ac-
curately 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.
drobarometer is superior to former
consists in noting the height at stated
intervals. This necesstates a 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 receiver
placed in an office. The 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 a float, and in the OPP |
posite direction by means of a counter |
shaft and weight. The pulley. when it |
communicates it's 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 |
indicating 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 a |
bell when the height of the water |
reaches the limit desired. The record |
is made distinct and indelible on dial |
fourteen inches in diameter. Three in |
sulated wires connect the transmitters |
with the receiver and are operated by |
a battery of Prism Leclanche cells, |
placed in the Office. The transmitter |
and receiver may be located any dis |
lance apart. The battery is such as is in
use by all telephone lines, and requires |
40 attention. The instruments made
are of two classes, one indicating
heights in feet and inches and the
other in feet and decimals of q foot !"
