3 Application The S211 / S215 / S220 are three industrial dew point sensors designed for measuring dew point and related parameters in compressed air or industrial gases under specified operating conditions (See next page ). Parameter Default unit Pressure (optional) Remark: You can change the units using the service kit (optional) and the SFA software. The S211 / S215 / S220 dew point sensors are mainly used in compressed air systems in the industrial environment, and not developed to be used in explosive areas. To use them in explosive areas, please contact the manufacturer. Three dew...

7 Determination of the installation point 7 Determination of the installation point In order to maintain the accuracy stated in the technical data, the sensor must be installed correctly. The gas must flow on to the sensor tip, otherwise it will lead to wrong measurement values. For further instructions, please read chapter 8 carefully. Please consider that enough space exists at your site for a convenient installation. ATTENTION! Wrong 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...

8 Installation Before installing the sensor, please make sure that all components listed below are included in your package. Qty Description Item no. (Model dependent) Depending on orders: Plug: C219 0059 M12 plug or M12 cable Cable: A553 0104/A553 0105 Instruction manual Calibration certificate Remark: The item number of the model varies depending on the chosen measurement range and signal output. 8.1 Installation requirements The flowing air or gas must pass the sensor tip for a proper measurement. This can be realized with a measurement chamber. For an installation without the measuring...

8.2 Installation procedure The following steps explain the procedure of an appropriate installation. Installation with the measurement chamber 1. Insert the sensor into the measurement chamber and tighten it. 2. Connect the measurement chamber (with the sensor attached) to the quick coupling. Installation without the measurement chamber • Please check the size of the nozzle and make sure not less than 1/3 of the sensor tip is inside of the pipe. Install the sensor only if the system is pressureless. The inner thread must be G 1/2”
