دتکتور گاز برند MSA مدل IR700 Point
(MSA Brand carbon dioxide gas detector Model IR700 point)
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
assing 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.
The IR700 IR point detector is available in either an aluminum or stainless steel housing and is designed for use in Class I, Div.
۱, Groups B, C & D and Zone 1 areas for North America and Zones 1 and 21 internationally. The housing is IP66/ Type 4X rated.
