Compact humidity and temperature sensors in shape of a bar - PC RC series
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 fi lter types ZE 21 resp. ZE 22 (not recommended for the series .../9, see product info sheet F 5.1).
