The PyroUSB Series measures temperatures from
-40°C to 1000°C accurately and consistently, with an
outstanding response time of 240 ms. The 4 to 20
mA output is compatible with almost any indicator,
controller, recorder, data logger etc. without the need
for special interfacing or signal conditioning.
Model PU151 has 15:1 optics making it suitable for
most applications. PU301 is specially designed for
distant targets and has an optical resolution of 30:1.
PUCF is designed for small targets and measures a
spot size of ø5mm at 100mm distance.
All PyroUSB Series sensors are fully congurable
from a PC using the CalexSoft software and USB
cable supplied. This user friendly software enables
the user to set the range and emissivity, compensate
for reected energy; apply ltering; select max, min,
average or instantaneous readings; and peak or
valley hold processing. These features can also be
monitored and adjusted by an OPC Client. Other
features include Data Acquisition, Alarms and a
Scrolling Graphical Display.
The sensor will operate with either the 4 to 20 mA
cable connected, the USB cable connected, or both.
The USB cable has an IP65 connector at the sensor
end. An IP65 cap protects the sensor when the USB
cable is not connected.

GENERAL SPECIFICATIONS
DIAMETER OF TARGET SPOT MEASURED VERSUS DISTANCE FROM SENSING HEAD
AIR PURGE COLLAR
The air purge collar
is used to keep dust,
fumes, moisture and
other contaminants
away from the lens. Air
ows into the tting on
the side and out of the
aperture at the front.
FIXED MOUNTING BRACKET
The L-shaped xed
mounting bracket oers
a rigid support for the
sensor and allows ne
adjustment in a single
plane.
ADJUSTABLE MOUNTING BRACKETS
The adjustable mount-
ing bracket consists
of a xed mounting
bracket plus another L-
shaped bracket. When
assembled as shown
the adjustable mounting
bracket oers a rigid
support for the sensor
and allows ne adjustment in two planes.
AIR/WATER COOLED HOUSING
The air/water cooled
housing allows the
sensor to withstand
ambient temperatures
which exceed the
normal 70°C limit. Air
or water (depending on
the degree of cooling
required) ows into one of the ttings on the side and
out of the other. To prevent condensation forming on the
lens, the air/water cooled housing is supplied complete
with an air purge collar. Please note, the air/water
cooled housing must be ordered with the sensor and
cannot be tted by the user.
LASER SIGHTING TOOL
The Laser Sighting
Tool screws onto the
front of the sensor
during installation and
indicates precisely
where the sensor
is aiming. Once the
sensor has been
aimed at the centre
of the target and locked in position the Laser Sighting
Tool can be removed. The laser is activated by means
of a push button on the front of the tool which has a
latching mechanism.
