NTRODUCTION
The ID2202 (code D.A. 5122000031) is a device, of the ON/OFF type, that detects the presence of hot
materials, that is to say, materials that emit infrared radiation (IR).
The ID2202 can replace, with additional functions and improved features, the ID2200 and ID2000
models.

RINCIPLE
The ID2202 uses an IR sensor to measure the quantity of infrared radiation that is present in its field of
view.
A digital output is activated in the presence of hot material, or when the output signal of the sensor IR
exceeds a threshold value, which can be set by a potentiometer.
A second digital output provides an indication of the reliability of the detection, signalling anomalies in
its functioning or excessive closeness to the threshold of detection, and therefore a possible error.
A digital input allows you to select the HMD sensitivity, so as to ensure a reliable detection of both
‘cold’ (T > 450°C), and ‘hot’ (T > 650°C) material s.

IELDS OF APPLICATION
The ID2202 is designed specifically for use in steel hot rolling mill plants, but it can also be used in
similar applications (i.e. continuous casting, or detection of the presence of hot bodies in non-ferrous
metals).
The manufacturing characteristics of the photodetector make it suitable for use in heavy industrial
environments.
The photodetector is prepared for electrical supply by low-voltage continuous current. The output
connectors are protected against overloads and over voltages.
