  • OTDRs and Fault Locator

    AFL

    AFL optical time domain reflectometers (OTDRs) and fault locators are used to certify new fiber installations and locate faults in deployed fiber optic networks. OTDRs and fault locators are available for both multimode and single-mode networks, including FTTx PONs. OTDRs scan fiber optic networks from one end of the fiber, displaying a trace and reporting detected events such as splices, connectors, micro- or macro-bends and fiber end. Fiber length is reported along with location, loss and reflectance of detected events. Several OTDRs are available with an integrated visual fault locator (VFL), optical light source (OLS), and/or optical power meter (OPM). OTDR results can be saved and uploaded to PC for further analysis and/or archiving.

  • IR Sensor

    JonDeTech

    The world’s thinnest IR sensor. JonDeTech’s new generation thermopiles generates a direct, proportional voltage response when subjected to infrared radiation. The sensor registers wavelengths from 250nm – 22,5μm i.e. visual light up to the mid infrared region. The unique geometrical configuration where the thermocouples are “vertically” arranged enable the sensor to measure heat flux as well as temperature, i.e. the heat gradient over the thickness of the thermopile chip is actually measured. The sensor measures a very useful 0.17 mm in thickness and is made of plastic.Essentially it is a piece of robust plastic that can be used “bare” – withoutprotective housing, such as a metal casing commonly used by other producersThe sensor it is less than 0.2 mm. thin and it is made using plastic membrane. This configuration make the sensor so robust it can be used “bare” – without protective housing such as a metal container. Our sensors enables unique applications within the temperature and flux measurement fields

  • The Leading Measurement System for the Analysis of Porous Materials

    ELWIS - Autoneum Holding AG

    ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.
