How does LEDPOINT® PRS perform in environments with high humidity, mist and fog or when rapid changes of temperature occur?
LEDPOINT® PRS output is unaffected when used in high humidity, mist or foggy conditions at constant temperature. This has been proven in tests conducted in environments up to 99% relative humidity. However in common with all infra-red sensors, either designs with direct focusing optics or with the less satisfactory labyrinthine optical system, the LEDPOINT® PRS output can be affected by condensation caused by rapid environmental temperature changes. It is generally accepted that the most extreme level of rate of temperature rise that is seen in real installations worldwide is 0.33 o C/minute. In common with other professional infra-red based sensors LEDPOINT® PRS is able to function satisfactorily in such environmental conditions which are certainly more extreme than found in UKCS installations. Operation in thick mist conditions and jet washing is shown in video footage on a CD available from AMGas on request or which can be downloaded here.
