OMEGA’s new low-cost 
OS102 Series mini infrared 
transmitter system features a remotely 
mounted infrared temperature sensor and 
high-performance, microprocessor-based 
signal conditioner with built-in LED display. 
The OS102’s miniature sensor head design 
is ideal for measuring temperature in 
confined, hard-to-reach places and harsh 
environments. The sensor head is 
connected to the main electronics housing 
via a 1.8 m (6') shielded cable standard on 
all models. The signal conditioner’s main 
electronics are mounted in a rugged 
NEMA 4 (IP66) rated diecast aluminum 
housing and feature adjustable emissivity, 
linear voltage, and current output calibrated 
for the temperature range of -18 to 538°C 
(0 to 1000°F). A user-adjustable high/low 
alarm output is standard on all models.
