Feuchtesensoren
Die Feuchtesensoren der HIH-Serien bieten durchweg eine mit Instrumentenqualität vergleichbare Sensorleistung zur Erfassung der relativen Luftfeuchtigkeit in einem äußerst kostengünstigen Gehäuse.
Dabei handelt es sich bei diesen Feuchtesensoren um ein lasergetrimmtes, wärmeausgehärtetes kapazitives Sensorelement aus Polymer inklusive der chipintegrierten Signalaufbereitung. Die HIH Serien eignen sich in hohem Maße für die OEM Erstausrüstung.
Neben den lang bewährten analogen Feuchtesensoren der Serien HIH-4000-xxx gibt es auch neue, digitale Ausgangssensoren der Serien HIH-6000, HIH-6100, HIH7000, HIH8000 und HIH9000 zur Überwachung der Luftfeuchte (RLF) und der Temperatur, kombiniert in einem Standardgehäuse ( SOIC-8 SMD oder SIP 4 Pol ) mit unterschiedlichen Genauigkeitsklassen. (Von +/- 4,5% bis +/- 1,7% Genauigkeit relativer Feuchte)
Beigefügte Tabelle zeigt die gängigsten Feuchtesensoren:
