Measurements
The OMEGA® miniature, low-cost,
high-performance infrared sensor/
transmitter model OS136 features
a 19 mm (3⁄4") OD by 89 mm (3.5")
long stainless steel NEMA 4 (IP66)
housing. This mini transmitter is
ideal for applications that require
measuring temperature in hardto-reach, confined, or harsh
environments. The OS136 comes
with a 1.8 m (6') shielded cable
for power and output connections.
Models feature industry standard
outputs that provide easy interfacing
directly to all meters, controllers,
data loggers, recorders, computer
boards, and PLCs. The fixed
emissivity of 0.95 allows for quick
and easy measurement requiring no
adjustment during installation
and use.
