General information

MELA®-humidity/-temperature sensors in this series are supplied with a robust aluminium die cast housing with an inox or aluminium sensor part to measure relative humidity or relative humidity and temperature in air and other non-aggressive gases for a working temperature range of up to 200°C. The pressure-proof executions „D“ and „HD“ can be used at pressures up to 25 bar, at temperatures up to 125°C or up to 160°C. These sensors are ideally suited for industrial applications, e.g. in drying processes. The advantages of the series .../9 are its improved dynamics, in particular at low air speeds and also its increased service life, even under more challenging operating conditions (pollutant impact or permanent humidity > 95 %rh). When air speeds are extremely high combined with a hig
