  • Tractor Output Tester

    Model 137 - LITE-CHECK

    Lite-Check, LLC (Lite-Check) – a subsidiary of Lite-Check Fleet Solutions, Inc. – in Spokane, WA is introducing a new product to its lineup, the Model 137 Tractor Output Tester. 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.

  • Variable Power Supply

    VS-10a - Allied Edison LLC

    The VS-10a power supply is a light weight, portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 10 amps, thus the name VS-10a. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-10a is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case.

  • 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.
