Application
Sensitive to infrared radiation, the DC 2038 is a Hot Metal Detector for material at temperatures at or above 500^o C. The special design of this sensor and its rugged construction allow it to withstand the severe environmental conditions found in the steel industry. The fiber optics permit detection of products which are difficult to detect (due to physical obstructions, space limitations, etc.) even in areas of high ambient temperature.

Introduction      Up
The DC 2038 is a self-contained sensor complete with:

• A metal-jacketed fiber optic cable (with optional lenses)
• A cast aluminum housing containing the complete electronic assembly, power supply with transformer, photosensitive element, and amplifier with "totem-pole" output

Working Principle     Up
The infrared radiation emitted by the hot product is received by the fiber optic cable and transmitted to the photosensitive element. The current produced by the photocell enables the electronic circuits to deliver an all or nothing signal when hot product is in the field of view of the fiber optic cable.

Special Features    Up

• Angle of view: 2, 12, 24 or 36 degrees
• Photocell for detection at low temperatures
• All electronics are on one plug-in PC board
• Controls included under the rear cover include a test button used to simulate a hot product, a sensitivity adjustment potentiometer, an indicating LED, and a "gunsight" viewing port for aligning the sensor
• As an option, a mounting foot with an air purging connection can be added to the lens assembly; a water cooling jacket for the lens assembly is also optional
