The OMEGA® Infrared Series is a range of high
quality, low cost, compact sensors which measure the
temperature of inaccessible or moving objects and
materials. They measure temperatures from -20 to
500°C (-4 to 932ºF), accurately and consistently, with
an outstanding response time of 240 mS. OMEGA
sensors transmit the target temperature as a
4 to 20 mA output and offer a simple solution for most
non-contact temperature measurement applications.
The sensor’s emissivity setting can be adjusted from
0.2 to 1.0 to cope with different target materials and is
controlled by a 4 to 20 mA input. This gives the
opportunity to adjust the emissivity setting
automatically from a programmable logic controller
(PLC). Alternatively the emissivity setting can be
adjusted manually using the OS210-PT. If the
4 to 20 mA input is left open or short-circuit the
emissivity setting defaults to 0.95.
