PyroUSB Series, non-contact infrared sensors, measure temperatures from -40°C to
1000°C and provide a linear 4 to 20mA output. The 2-wire signal is compatible with
almost any indicator, controller, recorder, data logger etc., without the need for special
interfacing or signal conditioning. They are suitable for most materials such as food,
paper, textiles, plastics, leather, tobacco, pharmaceuticals, chemicals, rubber, coal and
asphalt.

DISTANCE AND SPOT SIZE
The size of the area (spot size) to be measured determines the distance between the
sensor and the target. The spot size must not be larger than the target. The sensor
should be mounted so that the measured spot size is smaller than the target.
AMBIENT TEMPERATURE
The sensor is designed to operate in ambient temperatures from 0°C to 70°C. For
ambient temperatures above 70°C, an air/water-cooled housing will be required.
Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambi-
ent temperature.
ATMOSPHERIC QUALITY
Smoke, fumes or dust can contaminate the lens and cause errors in temperature
measurement. In these types of environment the air purge collar should be used to
help keep the lens clean.
ELECTRICAL INTERFERENCE
To minimise electromagnetic interference or ‘noise’, the sensor should be mounted
away from motors, generators and such like.
WIRING
Check the distance between the sensor and the indicating/controlling device. If neces-
sary, the PyroUSB sensor can be ordered with a longer cable attached.
POWER SUPPLY
Be sure to use a 24Vdc, (22mA) power supply.
mecHanical inStallation
All sensors come with a 1m cable and a mounting nut. The sensor can be mounted
on brackets or cut outs of your own design, or you can use the fixed and adjustable
mounting bracket accessories which are shown below.

AIR/WATER COOLED HOUSING
The air/water cooled housing shown below allows the sensor to withstand high ambient
temperatures. It is equipped with two 1/8” BSP fittings. Water temperature should be 10°C
to 27°C for efficient cooling. Chilled water below 10°C is not recommended. To avoid
condensation, the air purge collar should be used with the water-cooled housing.

AIR PURGE COLLAR
The air purge collar below is used to keep dust, fumes, moisture, and other contami-
nants away from the lens. It must be screwed in fully. Air flows into the 1/8” BSP fitting
and out of the front aperture. Air flow should be no more than 0.5 to 1.5 litres/min.
Clean or ‘instrument’ air is recommended.

electrical inStallation
The sensor to electronics cable is a 1m, PVC cable. One end is attached, at the factory,
to the sensor head. The other end has a pair of wires and a shield (ground) wire.
WIRING
The PyroUSB sensor can be used in 3 different ways as shown below. To use the
4-20mA output, connect the PyroUSB sensor to the controller/indicator with the
24Vdc power supply in the loop using the following table and connection diagram as
a guide. The maximum loop impedance is 900 ohms. Note: The PyroUSB sensor
must be grounded at only one point, either the cable shield or the sensor housing.
Output Wire No. Wire Colour Function
4 to 20mA 1 Red Power supply + / signal +
2 Black (Blue) Power supply - / signal -
3 Bare Shield ground
Alternatively, to use the USB output, connect the PyroUSB sensor to a PC using the
cable provided. No external power supply is required when using the USB output. The
PyroUSB sensor can also be used with both the 4-20mA loop and USB connected,
provided that the negative terminal of the 24Vdc power supply being used is not
grounded. Note: The CalexSoft software must be installed before connecting the
sensor to a PC.

• The recommended minimum computer specification is:
Intel Pentium processor
VGA display with 640x480 resolution
USB 2.0 port
INSTALLATION
1. Insert the disk provided
2. Installer should run automatically (if not, select the appropriate drive and double click
on Setup.exe)
3. Follow the on-screen instructions
NOTE Do not connect the PyroUSB Sensor to the PC before the software is
installed
CONNECTING THE PYROUSB SENSOR TO A PC
1. Connect the circular connector on the USB cable provided to the PyroUSB sensor

program
configuration
• Setting Temperature Units
Temperature units can be set on the main temperature panel by pressing °C or °F.
• Setting Output Processing
The temperature range for the 4 to 20mA output, the averaging period and the peak/
valley hold processing can be set by using the main program menu to select:
[Setup] → [Output Processing]
The temperatures corresponding to 4 and 20mA can then be set (minimum –40°C,
maximum 1000°C, minimum span 100°C, maximum span 1000°C).
To minimise the the effects of temperature fluctuations, noise etc on the output
signal, the averaging period can be set between 0 and 60 seconds.
If required, Hold Processing can be applied by setting hold mode to Peak Hold or
Valley Hold and setting a hold period between 0 and 1200 seconds.
• Setting Target Emissivity
To set an Emissivity value for the PyroUSB Sensor, use the main program menu to
select:
[Setup] → [Emissivity]
Emissivity can then be set to a value between 0.1 and 1.0, or selected from a pre-
set list of materials by selecting [Data].

• Setting Reflected Temperature Compensation
To enable and set reflected temperature compensation, use the main program menu
to select:
[Setup] → [Reflection Compensation]
Reflected temperature compensation can be enabled/disabled using [Compensate
for Reflected Temperature], and when enabled the temperature value can be set
between -40 and 1000°C.
operation
Once the sensor is in position and the appropriate power, air, water, and cable con-
nections are secure, the system is ready for continuous operation by completing the
following simple steps:
1. Turn on the power supply
2. Turn on the instrument or PC
3. Read / monitor the temperature
IMPORTANT
Be aware of the following when using the sensor:
• If the sensor is exposed to significant changes in ambient temperature (hot to cold,
or cold to hot), allow 20 minutes for the temperature to stabilise before taking or
recording measurements.
• Do not operate the sensor near large electromagnetic fields (e.g. around arc welders
or induction heaters).
Electromagnetic interference can cause measurement errors.
• Wire must be connected only to the appropriate terminals.
maintenance
Our customer service representatives are available for application assistance, calibra-
tion, repair, and solutions to specific problems. Contact our Service Department before
returning any equipment. In many cases, problems can be solved over the telephone.
If the sensor is not performing as it should, try to match the symptom below to the
problem. If the table does not help, call Calex for further advice.
TROUBLESHOOTING
Symptom Probable Cause Solution
No output No power to sensor Check power supply
Erroneous temperature Incorrect wire connection Check wire colour codes
Erroneous temperature Faulty sensor cable Verify cable continuity
Erroneous temperature Field of view obstruction Remove obstruction
LENS CLEANING
Keep the lens clean at all times. Any foreign matter on the lens would affect measure-
ment accuracy. Blow off loose particles (if not using the air purge accessory) with an
air ‘puffer’.
GUARANTEE
Calex guarantees each instrument it manufactures to be free from defect in material
and workmanship under normal use and service for the period of one year from the
date of purchase. This guarantee extends only to the original buyer according to Calex
