  • High Elongation Extensometers

    Model 3800 - Jinan Testing Equipment IE Corporation

    The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use high precision, low friction potentiometers, and, as a result, have a wide range of factory selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They can be provided with high level outputs (approximately 2-8 VDC) or ones that mimic strain gaged devices (2-4 mV/V). When set to mimic strain gaged extensometers, the Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. The potentiometers employ a hybrid wire wound around conductive plastic, which provides excellent long term stability. The output from the extensometer is readily interfaced with most existing test controllers, and may be directly input to data acquisition systems and chart recorders. Please let us know at the time of order what type of output and connector you require.

  • Optical Fiber Cable Testing Equipment

    Torontech Group

    Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

  • Protection Relay

    Arc-Flash - Selco USA, INC

    Arc-Flash Relay is a high-speed, arc-detection device for electrical power-distribution systems. The protection relay has outputs for trip coils in several zones, and has inputs for up to several optical sensors for optimal arc detection. The inputs support both point sensors and fiber-optic line sensors,which cover a larger area.Using optical sensors rather than relying strictly on current measurement allows a much faster detection time than overcurrent relays or a circuit breaker alone can typically provide, as the light from the arc is unique for the fault, whereas current pulses above the nominal level are part of normal operation for many systems.On the occurrence of an arc fault, the protection relay detects the fault and pulses the trip contact in less than one millisecond, which trips the circuit breaker(s) supplying the fault. The total arcing time is effectively reduced to the mechanical opening time of the circuit breaker, typically between 30 and 75 milliseconds. This reduces the energy of the arc fault significantly, increasing worker safety, reducing fault damage, and improving uptime. Switchgear can often be simply cleaned, inspected, and put back in service after an arc fault instead of having to be replaced.

  • 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.
