The Omega miniature, low-cost,
high-performance infrared sensor/
transmitter model OS136A features
a 19 mm (
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 OS136A model
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.
