Mela®-humidity/-temperature sensors in the PC.S and PC.S-ME
series are compact sensors in a rod-type design with plug-in con-nection to measure relative humidity and temperature (individually
or together ) with high precision in air and other non-aggressivegases. They can be used for a wide range of applications.The scope of delivery includes the coupling plug without a cable. Allthe sensors in the series are equipped with a ZE 17-type gauze filter(resp. ZE 20 membrane filter for -ME design). We recommend thatyou use the version with the ZE 21/22 1)
type sintered high-gradesteel filter at high wind speeds or if the sensor is exposed to saltmist, sand or dust (near the sea, industrial estates etc.).(filter programme see product info sheet no. F 5.1).In the .../9 series the humidity sensor element is directly protectedby a PTFE filter. The advantage of this is the improved temperaturedynamics, in particular at low air speeds. In the ..../9-ME series aglass Pt-100 is used.

2-in-1 meteorological sensor probe with waterproofconnector. Temperature, Humidity, Dew point andFrost point output. Ultra-low 800 micro Amp powerconsumption eliminates self heating in Meteorologicalapplications. Meets WMO requirements for accurateair temperature, humidity and long term stability.Also features triple lightning protection and Surge,Transient & ESD protection.

Ambient Temperature is the measurement of air temperature basedon PT100 sensor built-in the water-proof and anti-UV shelter. It canbe widely useful for application of ambient temperaturemeasurement in agriculture, forestry, meteorology as well as aclimate chamber, warehousing etc. A radiation shield (7 louvers) toprotect the sensors from solar radiation and rain is included with thesupply.
