Calex PyroEpsilon Série Guide De L'opérateur page 2

PyroEpsilon non-contact infrared sensors measure temperatures from -20°C to 500°C and
provide a linear 4 to 20mA output. This output signal is compatible with almost any indicator,
controller, 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
materials 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 PyroTune module. If the 4-20
mA input is left open or short-circuit, the emissivity setting defaults to 0.95.
