Omega OS212 Série Mode D'emploi page 3

OS212 Series non-contact infrared sensors measure temperatures from -20°C to 500°C and pro-
vide a linear 4 to 20mA output. This output signal is compatible with almost any indicator, control-
ler, recorder, data logger etc., without the need for special interfacing or signal conditioning.
The sensor's emissivity setting can be adjusted from 0.2 to 1.0 to cope with different target mate-
rials and is controlled by a 4-20 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 optional OS210-PT module. If the 4-20 mA input is left open or short-
circuit the emissivity setting defaults to 0.95.
