NOTE:
The OS 137 A
Model
is a precision , miniature infrared transmitter . It
measures temperature via non -contact , and provides an analog output
proportional to the measured temperature . The OS137A
Model
is
offered
in
three
temperature ranges:
0
to
100ºC
(32
to
212ºF),
-18
to
260ºC
(0
to
500º
F)
and
-18
to
538ºC
(0
to 1000ºF).
The
analog
output
is
offered
as
4
to
20
mA ,
0
to
5
Vdc ,
0
to
10
Vdc ,
10 mV /degree
C
or
F,
or
K
type
thermocouple.
The
unit
provides
adjustable
emissivity
from
0.5
to
1.0,
10
to
1
optical
field
of view,
and
field
adjustable
alarm
output.
The
super-compact
design,
25.4
mm
OD
x
127
mm
length
(1.0”
OD
x
5.0”
L) is
ideal
to
measure
temperature
in
confined,
and
hard
to
reach
places.
The
Stainless
Steel
housing
is
NEMA-4
rated.
The
unit
comes
standard
with
a
1.82
m
(6’)
shielded
cable.
