System Description

The EnergyTech 401 monitor consists of four items (see Figure 1):
an infrared transmitter unit to project a beam of infrared radiation across the
duct
a receiver to measure that radiation
a power supply unit to provide the necessary power rails, and
a signal processor to compute the gas concentration from the signals provided
by the receiver unit.
Each of these units is designed to be rugged and durable. They are all fully
sealed to IP 65 standards and are suitable for outside mounting, without the
need for further weatherproof enclosures.
