Humidity/-temperature sensor
Meteorological design
Description

Mela®-humidity/-temperature sensors in the PC-ME series with
a fixed connecting cable (5 m), PK-ME series without cable or RCME series with a robust aluminium connecting head and terminal
screws are compact sensors in a rod-type design. They have a
high degree of accuracy and have been specially developed for
meteorological applications. All the sensors in the series are fitted
with the ZE20-type membrane filter.
We recommend that you use the version with the the ZE 21/ZE22
¹) type sintered high-grade steel filter (filter programme see product
info sheet no. F 5.1)at high wind speeds or if the sensor is exposed
to salt mist, sand or dust (near the sea, industrial estates etc.).
The advantage of the .../9 series is the improved temperature
dynamics, in particular at low air speeds.
t
1) In the series …./9 it is not possible to exchange the protective plastic t
t basket ZE16 with other filters.
