При необходимости, уточнить общий вес и габариты или размер отдельной части измерителя Вы можете в нашем сервисном центре. Наши инженеры помогут подобрать полный аналог или наиболее подходящую замену на интересующий вас прибор. Все аналоги и замена будут протестированы в одной с наших лабораторий на полное соответствие Вашим требованиям.

Основная особенность нашего интернет магазина проведение объективных консультаций при выборе необходимого оборудования. У нас работают около 20 высококвалифицированных специалистов, которые готовы ответить на все ваши вопросы.

В технической документации на каждый прибор или изделие указывается информация по перечню и количеству содержания драгметаллов. В документации приводится точная масса в граммах содержания драгоценных металлов: золото Au, палладий Pd, платина Pt, серебро Ag, тантал Ta и другие металлы платиновой группы (МПГ) на единицу изделия. Данные драгметаллы находятся в природе в очень ограниченном количестве и поэтому имеют столь высокую цену. У нас на сайте Вы можете ознакомиться с техническими характеристиками приборов и получить сведения о содержании драгметаллов в приборах и радиодеталях производства СССР. Обращаем ваше внимание, что часто реальное содержание драгметаллов на 10-25% отличается от справочного в меньшую сторону! Цена драгметаллов будет зависить от их ценности и массы в граммах.

• Page 9: What Is The Spa-2

  Determination of snowpack-properties can be very challenging as they vary significantly in space and time. The SPA-2 snow pack analyzer measures the volumetric contents of ice and water within a snowpack, and together with the snow depth calculates the snow water equivalent (SWE) and snow density.

• Page 20: How Does The Spa-2 Work

  The snow pack analyzer SPA-2 breaks this limitation and provides information about the snow pack by measuring the dielectric properties of a large snow volume. It provides all relevant snow properties like snow depth, snow density, snow water equivalent as well as the contents of liquid water and ice.

• Page 21: Installation

  3. There should be no boulders, trees, fences or other objects in the vicinity of the meas- urement spot. Any obstacle can cause snow drift and thus affect the measurement results. 4. If feasible, the SPA-2 should be installed in the direction of the main wind. This minimizes dis- turbances by snow drifts.

  The position of cross-profile nr. 8 has to match the mount- ing position of the tilted SPA-sensor on the mast (see alsoMast with tilted SPA-2-sensor and USH-9)! 4. Place the U-profiles Nr. 5 between the base-profiles nr.1 and 3, and nr. 2 and 4 using the hori- zontal bolts mounted to the profiles.
• Page 25
  5. Adjust the bolts on each end of the U-profile so that they protrude 4 cm from the surface. You may need to lift the end of the base-profiles by a few cm to adjust the bolts. Tighten the lock-nuts. 6.

  3. Fix the mast with the upper bolt of the mast bracket on cross-profile nr. 11. 4. Slide the bracket for the cross-arm approx. 30 cm over the top of the mast and tighten it loosely. 5. Slide the cross-arm into the bracket so that the short end protrudes max. 5 cm and tighten it. Make sure that the cross-arm is pointing perpendicular to the length of the supporting frame when it is standing upright! Now, tighten the 4 bolts of the bracket embracing the mast.
• Page 29
  7. Plug the sensor cable to the USH-9 and fix it along the cross-arm and mast with cable ties. Coil up the excess sensor cable and attach it to the mast to avoid damage during the remaining installation steps. 8. Verify that the pulleys attached to the mast match the mounting position of cross-profile nr. 8.
• Page 30
  12. Run the cable nr. 23 through the second pulley as shown below. 13. Fix cable nr. 23 with a cable tie to the mast as shown below. Make sure to run the cable around the pulleys exactly as shown in the figure. Only then the hoist to tighten the SPA rib- bon sensor will work properly.

• Page 40: Power Supply

  7.3.8 Power supply The SPA-2 is designed for extreme environmental conditions at remote sites and with no grid con- nection. The sensor switches automatically into standby-mode between measurements and thus consumes only approx. 0.2 Ah per day (measurement duration 6 sec and measurement interval 60 sec) which can be supplied by a 12V-solar-generator mounted to the mast.

• Page 41: Lightning Protection

  Consult an expert for advice. The SPA-2 is protected against overvoltage. If a data logger is mounted to the mast, its ground lug must be properly connected to earth ground.

• Page 42: Maintenance

  11.5.2 What can I do with it? Modbus-communication with SPA-2 allows reading of measurement values and device information by a Modbus master. Additionally, the basic RS-485 port settings can be written to the SPA-2. 11.5.3 How do I wire it? For Modbus communication the SPA-2 is wired according to the table below.
• Page 76
  Follow the instructions below to change the communication of a Sommer-device (in this example a RG-30) to Modbus: 1. Connect the USB to RS-485 converter to the data cable of the Sommer-device and a USB port on your PC. 2. Connect the sensor to a power supply with the specified rating.
