Meteo Meteorological measurements – wind, precipitation, the sunlight In this chapter, basic information on the measurement of meteorological variables is provided, including examples and recommendations. The variables include... Illumination Measuring outdoor lighting, the sensor is installed by the customer The outdoor lighting is measured by the C-RI-0401S module, whose built-in version is placed in the flush box; it is terminated with a connector, to which... Illumination Measuring the intensity of outdoor lighting The intensity of outdoor lighting (N.B.: it serves for the measurement of indirect illumination - it is not a sun sensor!) is measured by the RI-C-0401I... Illumination Measuring the interior lighting The light intensity indoors can be measured by the C-RI-0401R-design module, which consists of two parts: The first, recessed part (corresponding to the... Illumination Measuring the lighting The intensity of lighting (also illuminance in accordance with ČSN EN 12665) is a photometric value defined as the luminous flux incident on... Dew and condensation Dew point monitoring (condensation on the distribution system of fan-coils, etc.) The condensation probes, based on the principle of insulated electrodes, can also be used for monitoring condensation. These probes are supplied e.g. by... Dew and condensation Measuring the dewing of a higher number of cooling ceilings, etc. A solution for a high number of measuring points with the peripheral Foxtrot module IT-1604. If it is necessary to monitor the dewing of ceilings... Dew and condensation Measuring dewing (protection against dewing on cooling ceilings, etc.) Dewing can be prevented using a special SHS sensor with the resistance characteristic and sensitivity to high air humidity. Typical applications include... Dew and condensation Measurements of dewing (condensation of air humidity) In order to prevent condensation on piping, cooling ceilings, walls of equipment, etc., there are special resistive dewing probes used (Chap.11.4.1). By... Air quality RH and temperature measurement for HVAC applications, the sensor with a 4÷20 mA output For measuring temperature and humidity in e.g. ventilation units, in agriculture, etc. Combined sensors with analogue output can be used, typically with... … 33 34 35 36 37 38 39 40 41 …
