  • Analog Sensors

    Solar Light Company Inc.

    Solar Light’s NIST-Traceable PMA-Series Analog Sensors represent the pinnacle of accuracy, durability, and selection on the market today. Our sensors measure discrete bands of the electromagnetic spectrum from the UVA, UVB, UVA+B, UVC, Visible Light, and Infrared regions. Both narrow and broad bands are available, to fit any application, including germicidal applications, environmental probes, and sensors for biologically weighted spectra (such as the erythema and CIE action spectra.) Over 135 different sensors are available in a variety of packages to fit any environment, from indoor clean rooms to harsh locations outdoors to 100 meters under water. Please note that Solar Light offers both Digital Sensors and Analog Sensors in the PMA-Series lineup. Select these Analog Sensors if you don’t need a digital display output of the reading, if you will be connecting to your own datalogger, or if you plan to use a voltage source to provide excitation voltage to the sensor and a digital volt or amp meter to read and convert the results. Analog Sensors are typically used as process sensors that are permanently installed to provide ongoing information. Typical current draw is under 1mA. (By contrast, Digital models are typically used as discrete sensors that are portable and located to provide short term information.)

  • Turns Ratio Testers

    TRT Advanced Series - IBEKO Power AB

    TRT Advanced series is the newest DV Power solution for transformer turns ratio measurement. Besides its main application, each turns ratio tester from this series also measures transformer excitation current and phase shift. Furthermore, all models perform automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. They have a built-in true three-phase power source. For that reason, they can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 500 V AC, depending on the model. With the highest test voltage 500 V AC, TRT500 provides the most accurate turns ratio testing of power transformers used in power generation and transmission. The output test voltage of TRT500 can be boosted to 5 kV AC using the external CVT20 extension transformer. This application is specially designed for testing turns ratio of capacitive voltage transformers. The other three models, TRT400, TRT250, and TRT100 can output up to 400 V, 250 V, and 170 V respectively. The low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT500 is equipped with a large 10.1” graphical touch screen display. Other models, (TRT400, TRT250, TRT100) have 7” graphical touch screen display. Besides making the interface much more user-friendly compared to older turns ratio testers, it also brings certain options that were previously available only with DV-Win software. The most important are test templates and automatic test mode. Users can simply create test templates, store them in the instrument’s memory, and load when in the field with just a few clicks.This turns ratio test set, as well as all other DV Power turns ratio testers, has a built-in tap changer control unit. It enables remote control of an on-load tap changer (OLTC) directly from the instrument. In order to make the most out of this feature, the instrument can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time. Automatic test mode minimizes human errors, which makes the measurement more reliable.

  • Radiation Microdosimeters

    Teledyne Defense Electronics

    Teledyne e2v HiRel Microdosimeter is a compact hybrid microcircuit which directly measures total ionizing dose (TID) absorbed by an internal silicon test mass. The test mass simulates silicon die of integrated circuits on-board a host spacecraft in critical mission payloads and subsystems. By accurately measuring the energy absorbed from electrons, protons, and gamma rays, an estimate of the dose absorbed by other electronic devices on the same vehicle can be made. The Microdosimeter can operate from a wide range of input voltages. The accumulated dose is presented to three dc linear outputs and one pseudo-logarithmic output giving a dose resolution of 14 µrads and a measurement range up to 40 krads. These outputs are intended to be directly connected to most analog-to-digital converters (ADCs) or spacecraft housekeeping analog inputs (0-5 V range), which makes minimal demands on the host vehicle. The Microdosimeter incorporates a test function to allow electrical testing of the hybrid without the need for a radiation source.

  • UV Cameras

    Inframet

    Solar blind UV cameras are imaging devices optimized to detect ultraviolet light of wavelengths below about 280nm. Such cameras are insensitive against sunlight due to negligible sensitivity to visible and long wavelength UV light. Solar blind UV cameras are used in a series of applications like corona detection, fire detection, combustion analysis, plasma research, testing UV lamps, etc. However, highly sensitive corona detection is the main mass application and these devices are of crucial importance in electric power industry. These imaging devices enable easy detection of degraded insulators of high voltage transmission lines, distributions and substations. They can see the emission of UV light when discharges occur at defect insulators. From design point of view solar blind UV cameras are actually bispectral imaging systems built by combining true UV camera with typical visible camera. These bispectral imaging system generate output image as overlay of typical visible image with UV image of analyzed UV source.
