Humidity/-temperature sensors

for industrial applications up to 200°C, up to 25 bar
Description

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 high number
of particles, using the series .../9 is not recommended.
