OMEGA’s new low cost OS100 
Series mini infrared transmitter system 
features a remotely mounted infrared 
temperature sensor and high performance 
microprocessor based signal conditioner. 
The OS100’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 conditioners 
main electronics are mounted in a rugged 
NEMA-4 rated diecast aluminum housing 
and feature adjustable emissivity, linear 
voltage, current or Type K thermocouple 
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.
