Laminaarisen ja turbulentin ilmavirran akustiset mittaukset edellyttävät matalaproofilisia antureita äänikentän häiriöiden minimoiseksi.
Siksi olemme GRAS: ssa kehittäneet UTP-mikrofonit - Ultra Thin Precision -mikrofonit. Ne yhdistävät klassisen mittausmikrofonin edut - laaja taajuusalue, tarkkuus ja toistettavuus - erittäin pieneen kokoon.
GRAS 48LX-4/8 on vain 1 mm korkea, ja siksi se on ihanteellinen mittauksiin pintarakenteissa ja turbulenssissa.
Quality Data
UTP provides accurate data from precision measurement microphones manufactured to narrow specifications. All LX-versions have TEDS.
Low Profile
With a height of 1,35 mm the door to a whole new world of what can be measured in boundary layers and turbulent flow opens.
Easy Mounting and Verification
As described below, mounting is easy with masking tape, and once mounted, the setup can easily and quickly be verified in-situ, a major advantage when you want to check the integrity of your measurement setup.
Small Form Factor and Simplied Cabling
48LX-4/8 can be used in small or difficult-to-access spaces where conventional microphones must give up.Easy connection and cabling.
Cost-saving Solution
Easy mounting, CCP interface with integral cabling and in-situ verification all add up to reduced setup time and faster measurements - with reliable data.
Flow-optimized Fairings
Fairings with a rise angle of 6.5 ensure minimal disturbance to the sound field/airflow.
It can be mounted using masking tape.
A special verification adapter with a soft cushion allows for quick, easy, and reliable in-situ verification. Four distance spacers ensure that the correct volume is achieved and that this volume can easily be reproduced. Even on curved surfaces, this verification method is so precise that dismounting is not necessary.
