Transducers

are

they

use perform_

ance-proven

Kyowa

strain

gages

as

sensing

elements.

Peripheral

equipment

commonly

a_

vailable

for

use

with

strain

gages

can

be

connected

direct

to

these

civil

en_

gineering

instrument,

allowing

more

inexpensive

automation

than

by

types.

And

the

indicator

for

use

with

these

transducers

employs

a

unique

circuit

developed

by

Kyowa

and

eliminates

the

need

for

correc_

tion

for

up

to

5 km cable

extension

to save

time

and

labor.

The

adding

force

of

Kyowa

UCAM

system

has

now

made

it

possible

to

connect

it

to

a

CpU

(Central

process_

ing

Unit),

thereby

requiring

no

per-

sonnel

at

the

administrative

office

for

dam

safety,

especially

those

in

charge

of

the

embedded

instruments.

For

such

an

efficient

and

economy

total

system

as embedded

instrumenrs

to

terminal

devices

connectable

to

a

computer,

look

to

Kyowa's

advanced

technology.
