These
popular units have been in production since 1980. They are considered rugged
and reliable. The coiled filament operates at approximately 900°C when
powered with 10 watts for the standard IR-12 and IR-12R sources and 975°C
when powered with 11 watts for the IR-12K. The radiating element is a coil
of resistance wire which has a high emissivity in the Infrared spectral
region. The coil is supported on a grooved cylindrical substrate of alumina,
resulting in the windings being electrically insulated from each other. This
contributes to a more uniform radiating source. The unit does not require
operation in a sealed atmosphere. The header is fabricated from cold-rolled
steel. The support pins are hermetically sealed in glass.
The IR-12 Series is offered in several configurations. The standard
IR-12 is shown below. The IR-12R is a standard IR-12 fabricated with the header
flange in the reverse direction. The IR-12 Series also includes the IR-12K which
uses Kanthal A-1 resistance wire for higher temperatures.
