Mela®-humidity/-temperature sensors in the PC.S and PC.S-ME
series are compact sensors in a rod-type design with plug-in connection to measure relative humidity and temperature (individually
or together ) with high precision in air and other non-aggressive
gases. They can be used for a wide range of applications.
The scope of delivery includes the coupling plug without a cable. All
the sensors in the series are equipped with a ZE 17-type gauze lter
(resp. ZE 20 membrane lter for -ME design). We recommend that
you use the version with the ZE 21/22 ¹) type sintered high-grade
steel lter at high wind speeds or if the sensor is exposed to salt
mist, sand or dust (near the sea, industrial estates etc.).
(lter programme see product info sheet no. F 5.1).
In the .../9 series the humidity sensor element is directly protected
by a PTFE lter. The advantage of this is the improved temperature
dynamics, in particular at low air speeds. In the …./9-ME series a
glass Pt-100 is used.
1) In the series …./9 it is not possible to exchange the protective plastic basket ZE16
with other lters.
