J-121

The DP1511, DP1521 and DP1531
non-contact infrared thermal
monitoring systems represent a
unique technological approach for
monitoring and controlling process
temperatures. These units combine
fiber optics or line-of-sight optics
with advanced electronic technology
into a system that continuously
monitors infrared radiation (a
function of temperature) in real time
and without physically contacting the
target material. The result is a highly
reliable system offering outstanding
accuracy and repeatability with high
response speed.

For OS1512 and OS1532 Infrared Sensors
and OS1513 and OS1533 Fiber Optic Sensors

Built-in synchronous demodulation
circuitry helps to minimize or
eliminate noise pickup from nearby
sources such as motors, induction
heating generators, etc.

The DP1511, DP1521 and DP1531
contain all of the electronics
necessary to amplify, linearize and
process the electronic signal
received from the detector head. In
addition, they provide a millivolt per
degree linear output, as well as an
optional second output of 0 to
10 Vdc or 4 to 20 mA, which can be
used for process control or
recording purposes.

On all three models, the front panel
digital pushbutton emissivity control
assures precise setting of the target
emissivity. If process parameters
are changed, this digital control
enables the operator to accurately
return to the previous settings.

A variety of signal processing options
is available (one per unit) such as
peak (or valley) sense and hold
(when the process temperature
sharply rises and falls), signal
averaging (to smooth out unwanted
variations in the temperature
measurement), sample and hold (to
sample a temperature and hold it for

a specified time), and fast rise
variable decay (which is similar to
peak and hold, but has a variable
decay time). These signal processing
options are adjustable by a front
panel variable control adjustment.

The DP1521 has four independent
input channels with a front panel
selector switch, each channel having
its own1 mV/degree output as well as
its own emissivity adjustment.

The DP1531 is a high speed single
channel monitor suitable for use on
any high speed event application
utilizing the 20 microseconds time

constant (0 to 63.2%). This system
utilizes an auto-zero circuit (with
shutter built into the detector head)
to zero out any system drift.

The DP1511 or DP1521 thermal
monitoring system consists of a fiber
optic assembly and detector head,
(or line-of-sight detector head),
connecting cable, and meter. The
DP1511 and DP1521 monitors are
used with either the OS1512 infrared
or OS1513 fiber optic sensors.

The DP1531 high speed monitor is
used with either the OS1532 infrared
or OS1533 fiber optic sensors.
