OS1592 Infrared Fiber Optic Thermometer/Transmitter 1 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.

OS1592 Infrared Fiber Optic Thermometer/Transmitter 2 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.

OS1592 Infrared Fiber Optic Thermometer/Transmitter 3 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. 3.1 - Changing the Temperature from °F to °C (or vice versa) Press the MODE key to go to either the MAX , MIN, or DIF display mode. Press the °F–°C key to change the temperature display from °F to °C or vice versa.
3 OS1592 Infrared Fiber Optic Thermometer/Transmitter 0-5VDC: Measured Temp = [ (Voltage Output ) x (T2 - T1)] + T1 5 0-10VDC: Measured Temp = [ (Voltage Output) x (T2 - T1)] + T1 10 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 any time by pressing the SET key in either the MAX, MIN, or DIF display modes.
