MELA® humidity/-temperature sensors in the PC, PK and
RC series are compact, versatile sensors in a rod-type design. They are available with a 1.5 m connecting cable (PC
series), without cable (PK series) or with a robust aluminium
connecting head and terminal screws (RC series) for measuring relative humidity, relative humidity and temperature or
temperature in air and other non-aggressive gases.
The advantages of the series .../9 are its improved dynamics,
in particular at low air speeds and also its increased serviece
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.
For extreme applications (near the sea, desert, mountains,
areas with high air speed etc.) we recommend our stainless
steel sinter filter types ZE 21 resp. ZE 22 (not recommended
for the series .../9, see product info sheet F 5.1).
