|
The screw cap of the screwed joint is connected with a protecting tube, which is perforated so as to enhance the ventilation of the sensor. The device can be mounted using two mounting holes, Ø 4 mm, in the bottom of the casing.
By unsoldering the 4 connection leads and loosening the screw cap (14 mm width) the protecting tube may be removed to replace the sensor if needed. Maintenance is not required, except for an occasional removal of dust. The connection can be implemented by means of 3 or 4 line connections.

The accurate measurement of rain and snow precipitation remains one of the most basic elements of hydrological and meteorology studies. The FT7360 Precipitation Gauge has been designed to measure rainfall and precipitation in remote and unattended locations. The FT7360 is a high quality instrument that provides accurate measurements with long term performance. The tipping bucket design allows accurate repeatable measurements, requires no regular operator maintenance, and is economical and proven in operation. All components of the FT7360 reflect the environmental requirements of a continuous duty instrument. |

The pyranometer is an instrument for measuring the solar irradiance. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square. The pyranometer is designed for continuous indoor and outdoor use. |

The Aspirator Psychrometer FT3060 series are used for measuring the air temperature and the humidity. Two parallel mounted, equal mercury thermometers are used. The bulb of one thermometer (wet bulb thermometer) is covered by a wick, which must be moistened for a measurement. The bulb of the other thermometer remains without wick. Both bulbs are encased by two radiation tubes. In order to achieve an effective radiation shield the surface of the instrument is polished. |

Humidity/Temperature FT3030 series Sensors are used for the measurement of the relative humidity and the air temperature simultaneously. A capacitive measuring element is used for the measurement of the relative humidity and a PT100 is used for the measurement of the air temperature. Both sensors are located in a measuring probe, protected by a membrane filter. The measuring probe is placed inside a solar radiation shield made of a defined white colored plastic. There is also an electrically ventilated version available for measurement of the exact temperature when wind or drift are absent. |

Electrically Aspirated Psychrometer FT3010 series provide continuous measurements of the "dry bulb" and "wet bulb" temperatures with high accuracy. From these two values the desired relative humidity and dew point temperature may be obtained by using psychrometric tables, diagrams or a computer system. The design of the instrument essentially eliminates the effects of wind and radiation. Inside the downward inclined radiation shield tubes, two platinum resistance thermometers (Pt100W) are mounted. |

Temperature sensor FT2030 series are equipped with platinum resistance thermometers Pt100, DIN 60751 B, tolerance class1/3 DIN, with 4-wire connection and 5m cable. The sensor is placed in plastic shaft and screwed into the base plate by means of a cable duct. The base plate is for senor mounting using two M8-screws, 30 mm apart. The radiation shield is designed to minimize the influence of short-wave radiation and long-wave radiative exchange. Radiation shield consists of 12 plates made of a special white plastic material. Its aerodynamically optimized design features efficient horizontal air flow. |

Sunshine duration is defined by WMO as the time during which the direct solar radiation exceeds the level of 120 W/m². It has no moving parts and uses 3 photo-diodes with specially designed diffusers to make an analogue calculation of when it is sunny. The output is switched high or low to indicate sunny or not sunny conditions. The calculated direct irradiance value is also available. The sensor has built-in heaters to dissipate rain, snow and frost. These are normally switched externally but an optional internal thermostat control is available. |
