Installation12Operating Instructions Radiation sensors R3XX3 Installation3.1 Installation location The ambient conditions at the installation location must be within thepermissible temperature and climate ranges. The corresponding datacan be found in Section 1.4 Technical data. The installation location should be free from vibrations and free ofelectromagnetic interference fields. Please also refer to the notes inSection 2 with respect to this. When choosing an installation location, please make sure that thepermissible operating temperature for the particular sensor (Sensorhousing temperature) is adhered to (see 1.4). In the case of a fairly high ambienttemperature, position the sensor in such away that it is not exposed to heatconvection from the measurement object(example 1). If such an arrangement is not possible, the sensor must be operatedwith an additional cooling jacket (example 2). The cooling jackets arefitted with a mounting flange (see accessories).In order to prevent inadmissible heating or damage to the sensor in theevent that the supply of cooling water is cut off, it is also necessary tomonitor the water circulation. BARTEC offers suitable flow controlinstruments.Note:The Thermophil® INFRAht radiation sensors must be positioned in such away that the cable between the radiation sensor and measuring amplifier isnot moved during measurement.Example 1WasserablaufWater supplySensorHeat sinkExample 2
