1. afety instructions
•Avoid direct UV and solar radiation during storage.
•For the storage the humidity has to be <90%, no condensation.
2. Application
The 220 is a dew point sensor which is designed to monitor the dew
point in industrial application within the permissible operating
parameters. These parameters can be found in the technical data
section.
The 220 can measure the following values:
•Temperature of the compressed air or gas.
•Humidity of the compressed air or gas.
•Dew point of the compressed air or gas.
The default factory settings are: temperature in °C, Humidity in % and
dew point in °C Td. Other units can be programmed by the optional
display or the service kit.
The 220 dew point sensor is not developed to be used in explosive
areas. For the use in explosive areas please contact the manufacturer.
The 220 dew point sensor is mainly used in compressed air systems in
industrial environment.
3. Features
•mall size makes it ideal for dryer installation.
•Measures dew point down to -100°C Td.
•Version with integrated pressure measurement.
•Various output versions available: 1 x 4 ... 20 mA, 2 x 4 ... 20 mA,
R -485 (Modbus), 4 ... 20 mA loop powered.
•IP65 casing provides robust protection in rough industrial
environment.
•Very fast response time ensures safe and reliable indication
whenever dew points are out of valid ranges.
•Can be installed directly into dryer through G ½” thread.
•High accuracy of ±2 °C dew point.

6. Determination of the installation point
6. Determination of the installation point
In order to maintain the accuracy stated in the technical data, the
sensor must be installed correctly. The air must flow on to the sensor
tip, otherwise it will lead to wrong measurement values. For further
instructions, please read the next chapter carefully.
Please consider that enough space exists at your site for a adequate
installation as described in this manual.
ATTENTION!
rong measurement is possible, if the sensor is not
installed correctly.
•The sensor is for indoor use only! At an outdoor installation, the
sensor must be protected from solar radiation and rain.
•It is strongly recommend not to install 220 permanently in wet
environment as it exists usually right after a compressor outlet.
7. Installation
Before installing the sensor, please make sure that all components listed
below are included in your package.

7.1 Installation Requirements
The flowing air or gas has to pass the sensor tip for a proper
measurement. This can be realized with a measurement chamber. For a
installation without measuring chamber you need to concern the
installation depth which is described in the next chapter.
