S+S REGELTECHNIK 1201-2111-1200-000 ESFTF-U LCD Einschraubbarer Feuchte

Die Feuchtetransmitter der HYGRASGARD ESFF / ESFTF-Serie dienen zur Messung der relativen Feuchte und Lufttemperatur in druckbeaufschlagten Systemen und wandeln diese Messwerte in Standardsignale von 4...20 mA oder 0-10 V um. Der Prozessanschluss ist G ½" gerade Rohraußengewinde, mit Klemmenkastengehäuse aus schlagfestem Kunststoff und Gehäusedeckel mit Schnellverschlussschrauben.
