The primary function is to deliver a continuous, regulated flow of clean, dry air or inert gas to optical windows and sensor assemblies, preventing contamination and maintaining a clear line of sight for accurate temperature measurement.
Typical parameters include a purge air flow rate of 15–60 L/min, supply pressure of 1.0–1.6 bar, air quality with a dew point of -40°C, and 1–8 purge outlets. Operating temperature ranges from -20 to 85°C, supply voltage is 24 V DC ±10%, and power consumption is 10–30 W.
Common materials include stainless steel (304) for housings and fittings, aluminum for manifolds, PTFE/Teflon for seals and gaskets, and quartz or sapphire for optical windows.
Verify model-specific values such as flow rate, pressure, air quality, and electrical specifications with the legal manufacturer or supplier. Ensure the system meets the required standards (e.g., ISO 8573-1 for air quality) and is compatible with the measurement system.
