DescriptionComponentItem

6 Magnetrons The magnetrons are 3 KW, 2450 MHz generators that convert high

voltage electrical inputs to RF energy.

6A Waveguide The wave guide directs the RF energy into the UV bulb, exciting a

UV-emitting plasma within the bulb.

7A External Blowers

Forced air is used to cool the UV bulb and magnetrons. If external

blowers are used, they must be sized appropriately to provide the

required air flow. Contact Nordson UV engineering for external cooling

air guidance.

7B Internal Blower

8 Temperature

Sensor

Monitors the lamphead internal temperature. The sensor consists of a

thermistor potted to a ring-tongue terminal and cable, which is

connected to the light detector board.

9 System Controller Provides and controls high voltage to the lamphead magnetrons and

controls other system functions.

10 RF Detector Detects leakage of microwave radiation. Will shut down system if

radiation is detected.
