  • Radiometer

    X1-1-RCH-116-4 - Gigahertz-Optik GmbH

    The X1-1 radiometer from Gigahertz-Optik features an RCH-116-4 detector and is ideal for measurement of the irradiance of high power LEDs in the UV-A and blue light range. The device can accurately measure irradiance levels of up to 40,000 mW/cm². One of the outstanding features of the RCH-116-4 detector is its proven concept of a passive radiation absorber coupled to a UV sensor. This provides stability even in high temperature and intense UV radiation environments. In addition to the passive radiation absorber, the device also has a cosine-corrected field of view. The sensor’s housing also serves as a handle. The battery-powered X1-1 optometer supports a usable dynamic range from less than 1 mW/cm² to 40,000 mW/cm² thanks to its high-end signal amplifier. It can be used to perform precise measurements of up to 5 standard LED wavelengths for which the detector was calibrated for active irradiance. In addition to the CW measurement function, the device also has a dose measurement function. The radiometer can be used with other detectors from the RCH series. e.g. for gas discharge lamps. Remote control of the device is possible via its user software and a software development kit is offered for integration of the device in the user’s own software.

  • SOLAR SIMULATOR

    Solar Light Company Inc.

    Solar Light offers 3 ranges of Solar Simulator products that satisfy the wide range of applications and markets where these products are used. The first range is the small laboratory models, the 16S range. These are used by education and research facilities, maybe pilot plants to set up, to demonstrate and prove the use of a solar simulator to produce UV radiation for such effects as fade testing, degradation testing, as well as sunscreen protection testing and so on. Each 16S solar simulator can output several times the UV level of natural sunlight, which enables accelerated testing to be carried out, saving time. All models comply with the prevailing standards and protocols for the particular testing they are being used for. For example, in clinical studies with sunscreens, they comply with the ISO standards, FDA and COLIPA. For materials testing, they comply with relevant ASTM, ISO and MIL standards. The 16S Simulators are also available with a full Air Mass 1.5 spectral output, which closely follows the solar spectrum and complies with the ASTM standards for Class A spectral match. This enables controlled research for photovoltaic testing and solar panel research.

  • Solar Tracking and Pyranometers

    Sutron Corporation

    The demand for energy increased rapidly over the past few decades and the trend is not expected to stop in the near future. These made researchers focus on renewable energy sources due to the environmental pollution caused by the existing conventional energy sources. Solar energy is one of the renewable energy that has been under deep research. Unfortunately, the main problem with this solar energy is lack of efficiency. Different positions of the sun throughout the day causing the static photovoltaic modules position inefficient. This paper discusses design of two-axis solar tracking system that considers multiple input parameters such as solar radiation and photovoltaic module output power for more efficient solar tracking algorithm. Some of solar tracking system conducted by other researchers uses various types of sensors including light dependent resistor (LDR) which is not efficient and can be easily affected by external environmental factors. Instead, this paper proposes the usage of pyranometer for measuring solar radiation as one of the input parameters. The solar tracking system controlled by PIC microcontroller that collects multiple input parameters and uses developed algorithm to control stepper motor movement for optimal photovoltaic module positioning.

Exclusively availablefor purchase through Lite-Check manufacturing starting mid- January, the Model 137 Tractor Output Tester is designed to test and diagnose safety concerns between the truck and trailer and trailers towing other trailers relating to Technology and Maintenance Council (TMC) recommended practices (RP) 137C, RP 141, RP 144, and RP 619B. Most testers on the market today test the truck and trailer separately with no consideration for how they work together. The introduction of RP 137C and its revisions seeks to ensure the voltage generated by the truck is sufficient to power the ABS of the trailer while under load. With the Model 137 Truck Tester, technicians can now verify that the voltage generated by the truck meets TMC RP 137C. Similarly, trailer testing can be accomplishedverifying the voltage recommendation for additional trailer hook-ups per TMC RP 141. Also, the ability to test howthe ABS cab light responds to a trailer’s ABS ECU is incorporated into the Model 137 Truck Tester.
