  • 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.

  • Programmable DC Electronic Load

    63000 Series - Chroma ATE Inc.

    The 63000 Series programmable DC electronic loads are reliable, precision instruments primarily designed to test switching power suppl ies, A/D power suppl ies, power electronic components, adapters, 3C batteries and chargers. Its maximum 350W rated power makes it suitable for testing numerous types of lower power devices. The 63000 Series offers models in two operating voltages 150V models, with 250W and 350W power levels up to 60A in a single unit. Their compact and light weight design make these loads easy to move around which is ideal for R&D and design validation. Each model of the 63000 Series has unique user-def ined waveform (UDW) funct ion capable of simulating real-world custom waveforms. In addition, a data storage function has been built in for saving and recalling up to 100 stored settings at any time. For automated testing, these save and recall functions can save a great deal of time. The 63000 Series has 3 power ranges that can precisely measure the voltage and current in real time. Since short circuit testing is a critical test item, the 63000 provides short circuit simulation to effectively address application demands for power and automated testing.

  • Receiver Semi-Kit

    75-NS-3 - National RF, Inc

    National RF’s 75-NS-3 receiver is a complete super-hetrodyne mini high frequency receiver, designed specifically for the short-wave listener, electronics enthusiast or radio amateur, who wants to use their hands and build a radio. The receiver is offered as a semi-kit in which the electronic assembly is loaded and functionally tested at the National RF facility. The customer must then go to the grocery store (yes…the grocery store!), procure a can of lunch meat, eat it or give it to the dog, and then proceed to drill and paint the can, in order for it to become the receiver’s enclosure! As the name of the preferred potted meat can has a registered trademark by Hormel Foods, Inc., it won’t be mentioned on this web-site. However, the name of the product is synonymous with unwanted email!!! In addition, there are other food products that might be found that are packaged in the same metallic enclosure. Detailed drilling instructions and final assembly instructions are provided as part of the kit. All other parts required for completion of the receiver are provided as well. Recognizing that the finished assembly looked somewhat like the fabled Collins receiver of the ‘60s, the 75S-3, (particularly when the can is painted a light gray) National RF engineers dubbed it (with tongue firmly planted in cheek, of course) the 75-NS-3! Although we have had fun packaging this receiver in a lunch meat can, it is nothing to turn your nose at! Its performance and portability will surprise you, and it is an ideal radio to bring with you on any trip!

  • Rugged, Long Gauge Length Extensometers

    Model 3543 - Jinan Testing Equipment IE Corporation

    With over 15 years of proven reliability in the world’s most demanding testing environments, the Model 3543 extensometer is designed to survive in those applications where standard axial extensometers would not. Designed by Epsilon, the Model 3543 was created to survive specimen failure by separating into two halves, thus preventing permanent damage to the module body. During operation, the upper half of the extensometer pulls out of the main body. Tapered measuring beams activate strain gaged flexures within the unit. This unique design allows long measuring ranges, yet retains compatibility with electronics for strain gaged transducers. These models offer high accuracy and are light weight but rugged, with low operating force. They are tension only units.The units have hardened tool steel knife edges. Standard quick attach wires provided with the extensometer work on flat specimens up to 12 x 31 mm (0.5 x 1.25 inch) and on rounds up to 25 mm (1 inch) diameter. Optional quick attach kit wire forms are available for use on larger samples. See Model 3542L for long gauge lengths with smaller measuring ranges.The Model 3543 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.

  • Heavy Duty Dynamometers

    MD-250-HD - Mustang Dynamometer

    The MD-250-HD series dyno (SE/DE) was designed to be a performance dynamometer first with the added benefit of being able to test 2-wheel-drive heavy-duty vehicles such as truck, buses and commercial vehicles in addition to the standard car or light duty pick-up. The 250-HD is certified in the states of Colorado, Nevada and Utah for use in loaded-mode diesel smog testing programs because of its accuracy and reliability. No other dyno in its class offers more value or better in-house motor vehicle testing capabilities than the Mustang MD-250-HD. For starters, the MD-250-HD boasts a 1,500 horsepower measurement capacity at a top speed of 175 mph and a powerful air-cooled eddy current brake provides the MD-250-HD-SE with 900-hp worth ofloading capacity for steady state testing. Loading capacity can be increased to 1,500-hp via the optional DE model. The 250-HD can be upgraded to the 250-HD-SE-M via the addition of a 100 or 200 hp AC motor for transient testing of electric buses to measure range and regeneration or for emissions testing of IC engines. Do not be fooled by its compact size – the MD-250-HD is a serious dynamometer with serious tuning capabilities. The MD-250-HD uses a powerful eddy current power absorber, a frictionless, air-cooled braking device, to enable it to apply variable and steady state loading. A complete control and data acquisition system lets you design a wide range of tests or select from a host of pre-configured tests included with the standard system. The 250-HD’s four roller design makes setting up vehicles a snap – simply drive onto the 250-HD and let the tires settle in between the rollers. The 250-HD can be installed above-ground or below-ground, it’s your choice. The above-ground system utilizes an optional premium platform and ramp system with an above-ground restraint kit. The addition of an axle pull-down kit help keep the tires from slipping or trying to “climb out” of the rollers.
