setting etc. from a PC via CalexSoft software
and USB cable (supplied)
•t Features max, min, average and instantaneous
readings; peak or valley hold; reflected energy
compensation
•t OPC Server capabilities
•t Temperature ranges from 45°C to 2000°C
•t Emissivity: 0.1 to 1.0
•t Stainless steel housing, sealed to IP65
•t Field of view: 15:1, 25:1, 75:1 or Close Focus
•t Selectable 0 to 20 mA or 4 to 20 mA output
•t Optional air/water cooled housing, air purge
collar, laser sighting tool and mounting brackets

The PyroUSB 2.2 Series of infrared pyrometers
measures temperatures from 45°C to 2000°C
accurately and consistently, with an outstanding
response time.

Models with temperature range 45°C to 300°C, or
100°C to 400°C have 15:1 optics.
For models with temperature range 250°C to
1000°C, or 450°C to 2000°C, a choice of optics is
available:

The selectable 0 to 20 mA or 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.

Note: The sensor must be grounded at only one point, either the cable shield or the sensor housing.

PU251-2.2 models have 25:1 optics and are
suitable for most target sizes and distances.
PU751-2.2 models are specially designed for distant
targets and have an optical resolution of 75:1.
PUCF-2.2 models are designed for small targets
and measure a spot size of ø 7.5 mm at 500 mm
distance.
All PyroUSB 2.2 Series sensors are fully configurable
from a PC using the CalexSoft software and USB
cable supplied. This user-friendly software enables
the user to set the temperature range and emissivity
setting, compensate for reflected energy; apply
filtering; select max, min, average or instantaneous
readings; and configure 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.
