OS1592 Infrared Fiber Optic Thermometer/Transmitter  
INTRODUCTION  
The new OS1592 series Infrared Fiber Optic Thermometer/Transmitter  
provides non-contact temperature measurement for industrial  
applications. The unit measures temperature starting at 260°C (500°F)  
and up to 2482°C (4500°F). It provides dual analog outputs (4-20 mA, 0-5  
VDC, 0-10 VDC, 1 mV/Deg, J & K type T/Cs) electrically isolated from  
the main input DC power supply. The 1 mV/Deg analog output is  
standard on all units.  
The main electronics is in a NEMA-4 rated Die cast Aluminum housing,  
with a local backlit LCD, built-in Relay, Alarm LED, and a 4 position  
programmable keypad.  
The unit accommodates any of the following assembly types:  
• Optical Assembly  
• Ceramic Tip Assembly  
• Polymer Bolt Assembly  
INSTALLATION  
2.1 Unpacking

2.2 – Electrical Connection  
Attach the optical assembly to the optical adapter located on the side of  
the housing. Refer to Fig. 1 for the overall appearance of the unit.  
Open the cover of the aluminum housing. Slide your cable through the  
metal feed thru and connect the wires to the 9 position terminal block  
(J101) as shown in Fig. 2. Depending on the type of the analog outputs,  
you need to make the proper connection. Connect the shield of the cable  
to the inside of the metal feed thru to minimize RF noise.  
In order to use the Backlight source OS1500-BLS, disconnect the fiber  
optic assembly from the main electronic unit and connect to the light  
source. The focused light through the fiber optic assembly provides the  
positioning of the optical assembly on the target. After the positioning,  
reconnect the fiber optic assembly back to the main unit.

NOTE:  
The Emissivity setting as well as the temperature Engineering unit (°F or °C) are  
stored in the non-volatile memory. Removing the main power will not erase or  
change these settings.

2. Press either the  
or  
keys to set the high alarm value.  
SET  
3. Press the  
key to enable the high alarm function. The  
icon  
appears on the display.  
If the temperature exceeds the high alarm set point, the unit goes into  
an alarm condition. The  
icon on the display flashes, the alarm red  
LED turns on, and the internal relay energizes. The relay contacts are  
brought out to the terminal block J101 for ease of access.  
SET  
4. To disable the high alarm function, press the  
key again, and the  
icon disappears.  
NOTE:  
1- The alarm temperature value as well as the alarm status are stored in the non-  
volatile memory. As a result, removing main power will not erase or change these  
settings.  
2- The alarm deadband is 10°C or 18°F.  
3.4 - Analog Output vs. Temperature  
The following equations relate the analog outputs of 4-20mA, 0/5VDC,  
0/10VDC to measured temperature:  
mA Output – 4

4-20mA:  
Measured Temperature = (

Where,  
T1 is the minimum temperature range  
T2 is the maximum temperature range  
3.5 - Resetting Temperature Values  
The calculated temperature values (Min, Max, and Diff) can be reset at  
SET  
any time by pressing the  
key in either the MAX, MIN, or DIF display  
modes. This will reset the calculated temperatures as follows:  
MAX = Current Temperature  
MIN = Current Temperature  
DIF = 0  
After the reset, the unit starts to keep track of the Maximum, Minimum,  
and Differential temperatures.

OS1592 Infrared Fiber Optic Thermometer/Transmitter  
MAINTENANCE  
Routine maintenance is not required except for periodic re-calibration,  
occasional inspection of the input and output ends of the fiber assembly  
for cleanliness, and a check for broken fibers if damage is suspected.  
The optical fibers will provide satisfactory service indefinitely if handled  
with normal care. Although the fibers are protected by a steel jacket, they  
can be damaged if the jacket is stretched, twisted, shocked or tightly bent  
to a small radius. The ends should be protected from damage,  
contaminants, and temperatures above 371°C (700°F). OMEGA does not  
warrant broken or damaged fibers due to mishandling.  
Fiber or lens damage or contamination should be suspected if there is a  
sudden change in the calibration of the unit.  
Dust and particles on the lens or on the output end of the fiber bundle  
may be removed by use of an air jet or a soft brush. Dirt films and other  
accumulations should be removed by the use of soft cotton or a Q-tip  
moistened with Windex, triple-distilled alcohol or other grease-free and  
solids-free solvent. A final wiping with dry cotton is recommended.  
If the fiber bundles are to be removed from the detector head assemblies  
for extended periods, the fiber bundle receptacles in the head should be  
taped or capped to prevent the entry of foreign matter.  
A periodic check of the electrical ground connection can be helpful in  
preventing RF-pickup problems.  
Fiber cables are not interchangeable, as a fiber optic cable assembly is  
calibrated with the electronic unit as a system.  
There is a gain adjustment for the fiber optic cable assembly inside the  
electronic box. This gain adjustment will compensate for any small shift in  
temperature reading due to aging of the fiber optic cable over time. Open  
the front cover of the Electronic Box. There is a small plug-in PC board  
with a potentiometer on one side. This potentiometer provides the gain  
adjustment for the fiber optic cable.
