Description

The Model IR700 infrared (IR) point detector is a
microprocessor-based carbon dioxide gas detector that
continuously monitors CO2 in ppm levels.

The IR700 detection principle is based on measuring
the absorption of infrared radiation passing through a
volume of gas using a dual beam, single detector method.
The IR detector measures the intensity of two specific
wavelengths, one at an absorption wavelength and
another outside of the absorption wavelength. The gas
concentration is determined by a comparison of these
two values.

All of the IR700’s electronics are contained within an
explosion-proof housing allowing detector information to
be processed at the point of detection. The IR700
provides 4-20 mA signal proportional to 0-100% full
scale. In addition, the IR700 is equipped with Modbus or
HART. Configurations with relays, Modbus, and HART
are available.

The IR700 is calibrated at the factory and needs no
routine field calibration. It requires only a periodic
cleaning of the windows and re-zeroing to ensure
dependable performance.

• Low maintenance

• Provides complete status and
control capability in the control room

Technologies wireless devices

The IR700 IR point detector is available in either an
aluminum or stainless steel housing and is designed for
use in Class I, Div. 1, Groups B, C & D and Zone 1 areas
for North America and Zones 1 and 21 internationally. The
housing is IP66 / Type 4X rated.
