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 ambi­ent 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 neces­sary, the OS150-USB 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.

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. Water
flow rate should not be more than 0.5 to 1.5 litres/min.

AIR PURGE COLLAR

The air purge collar below is used to keep dust, fumes, moisture, and other contami­nants 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 5 to 15 litres/min.

Clean or ‘instrument’ air is recommended.

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 OS150-USB sensor can be used in 3 different ways as shown below. To use the
4-20mA output, connect the OS150-USB 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 OS150-USB sensor

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

2 Black (Blue) Power supply - / signal ­ 3 Bare Shield ground

Alternatively, to use the USB output, connect the OS150-USB sensor to a PC using
the cable provided. No external power supply is required when using the USB output.
The OS150-USB 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 OmegaSoft software must be installed before connect-

ing the sensor to a PC.

omegaSoft Software

SYSTEM REQUIREMENTS

english

• OmegaSoft software is designed to run under Windows. Suitable versions are
Windows 2000, Windows XP, Windows Vista and Windows 7.

• 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 OS150-USB Sensor to the PC before the software is
installed

CONNECTING THE OS150-USB SENSOR TO A PC

1. Connect the circular connector on the USB cable provided to the OS150-USB sensor

2. Connect the USB A connector on the USB cable provided to an available USB 2.0
port

3. Double click on the OmegaSoft desktop icon

NOTE Do not disconnect the USB cable before closing down the OmegaSoft
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 OS150-USB 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].

8

›

• 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 con­nections 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, calibra­tion, 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 Omega for further advice.

english

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 measure­ment accuracy. Blow off loose particles (if not using the air purge accessory) with an
air ‘puffer’.

détecteur et la cible. La taille du point ne doit pas être plus grande que la cible. Le
détecteur devrait être monté de façon à ce que la taille du point mesuré est plus petite
que la cible.

TEMPÉRATURE AMBIANTE

Le détecteur est conçu pour fonctionner en températures ambiantes de 0°C à 70°C.
Pour les températures ambiantes supérieures à 70°C, un boîtier refroidi à l’air/eau est
nécessaire.

Eviter les chocs thermiques. Allouer 20 minutes au thermomètre, pour qu’il s’adapte à
d’importantes fluctuations de température ambiante.

QUALITÉ ATMOSPHÉRIQUE

La fumée, les vapeurs ou la poussière peuvent contaminer la lentille et provoquer des
erreurs dans la mesure de température. Dans ces genres d’environnement, le collier
de purge d’air devrait être utilisé pour aider à garder la lentille propre.

INTERFÉRENCE ÉLECTRIQUE
Pour réduire l’interférence électromagnétique ou ‘bruit’, le détecteur devrait être monté
à l’écart de moteurs, générateurs, et autres appareils similaires.

CÂBLAGE

Vérifier la distance entre le détecteur et l’appareil d’indication / de contrôle. Si néces­saire, le détecteur OS150-USB peut être commandé avec un câble attaché plus long.

ALIMENTATION ÉLECTRIQUE

S’assurer qu’une alimentation électrique de 24Vcc (22mA) est utilisée.

inStallation mécaniQue

Tous les détecteurs sont fournis avec un câble d’un mètre et un boulon de fixation. Le
détecteur peut être monté sur un support ou sur des découpes de votre propre con­ception ou bien les accessoires de support fixe et réglable, qui sont montrés ci-des­sous, peuvent être utilisés.
