LME Differenstryksensorer

Differenstryksensorer for ultralave tryk til manifold-montering

First Sensor præsenterer en ny manifold-miniaturekonstruktion af sine innovative differenstryksensorer til ultralave tryk med måleområder fra 25 til en slutværdi for måleområdet på 500 Pa (0,25 til 5 mbar). De meget flade sensorer i LME-serien med en højde på kun 9 mm inklusive tryktilslutningerne er perfekt egnede til indbygning i manifolds. Derudover kan miniature-tryksensorerne meget fleksibelt kombineres med kunde specifikke adaptere, f.eks. til applikationer med særlige monteringskrav som indenfor klimateknik.

LME-differenstryksensorerne, der er baseret på måling af et mikroflow, anvender en innovativ First Sensor-teknologi, hvor flowkanalen inklusive måleelementerne er integreret i en silicium-halvlederchip. Ved hjælp af denne ekstreme miniaturisering reduceres gasflowet gennem sensoren med flere størrelsesordener sammenlignet med traditionelle, flowbaserede tryksensorer. LME-differenstryksensorerne er derfor meget modstandsdygtige over for luft, der indeholder fugt og støv, og muliggør anvendelse af lange forbindelsesslanger og filtre uden påvirkning af den kalibrerede målenøjagtighed. Manifoldsensorerne opnår en høj målefølsomhed og nøjagtighed samt en utroligt god offsetstabilitet, der er bedre end 0,1 Pa/år. De små SMT-sensorer har et digitalt SPI-bus-interface og samtidig en analog udgang.

LME-differenstryksensorernes vigtigste egenskaber:
  • Meget flad højde på kun 9 mm inklusive tryktilslutningerne
  • Kan kombineres fleksibelt med kundespecifikke adaptere og manifolds
  • Mikroflowkanal integreret i silicium-sensorchippen
  • Meget modstandsdygtig over for luft, der indeholder støv og fugt

Eftersom LME-manifold-differenstryksensorerne er meget modstandsdygtige over for luft, der indeholder støv og fugt, opnår de særdeles lange levetider og forlængede serviceintervaller inden for klimateknik og medikoteknik. Derfor er sensorerne specielt velegnede til måling af selv meget små trykforskelle f.eks. i luftstrømregulatorer, filterovervågninger, brænderstyringer, respiratorer, anæstesiapparater, søvnapnø-apparater (CPAP), spirometre og iltkoncentratorer.
