1/6
· Tubular form for through wall mounting
· Product free from Lead, Cr(6+), Cd and Hg
· Calibrated, linear voltage for easy electronic interface
· Typical 1 to 1.6 Volt DC output for 0 to 20% RH at
5Vdc supply
· Ratiometric to voltage supply
· Patented solid polymer structure
DESCRIPTION
Based on the rugged HS1101LF capacitive humidity sensor, HM1520LF is a dedicated humidity transducer
designed for measurements at low humidity. Direct measurement of dew point or water concentration can be
easily obtained in really cost effective conditions. Direct interface with a micro-controller is made possible with
the module’s linear voltage output.
FEATURES APPLICATIONS
· Full interchangeability · Low Humidity
· Not affected by water immersion
· Meteorology
· Controlled temperature dependency …
