Relay / Magnetic Field Testers
PeakTech Prüf- und Messtechnik GmbH
Ideally suited for checking magnetic fields and the correct function of coils, e.g. Relays and solenoid valves. The magnetic field detector works without contact, so that opening the housing is not necessary in most cases. When a magnetic field is detected, the probe tip lights up permanently blue, with clocked relays in the same cycle as they are controlled. The function of the magnetic field detector can be checked before each measurement with the enclosed test permanent magnet.

Hardy Shaker
HI-913
This Hardy Shaker provides the ability to set the amplitude and change the frequency range without the amplitude changing. This automation makes conducting a test easier. A test can be conducted on a vibration transducer and manually recorded. Multiple tests are not saved; for multiple tests use the HI-903 or HI-803 units. The HI-913 is used for testing from 7 to 10,000 Hz, it offers adjustable frequency and vibration levels. This provides a reference source for verifying the accuracy of vibration transducers, connectors, cabling and instruments or instrumentation systems. The HI-913 has a ruggedized suspension system that can support heavy transducers (up to 800 grams - see frequency limits in the manual). The HI-913 has a built-in battery charger that can operate on 120 or 240 VAC. The unit comes in a rugged Pelican case.

Transportation Simulation
Transportation simulation testing involves the application or simulation of environments found in the transport of goods and equipment. These environments may include vibration, drop or shock, temperature, loose cargo or bounce, as well as other dynamic or climatic environments. Products and equipment are usually tested in the “shipping” configuration which means they would be packed in the default shipping container or transit case during the test. However, some items may also be tested in an unpacked state if there is an expectation that they might frequently be transported in that manner. Tests are performed not only to test the effects of transport on the product itself, but also to test the adequacy of shipping container design and the interaction between product and container during shipping. There are a number of possible modes of transport for any given item subject to shipping.

Motor Test for Electric Scooters
*The performance data of electric motors, in the majority of all cases, is performed by a brake test. Power input is calculated from current and voltage. Torque and power output are measured with a brake. It is important to reach, for each point, a persistent temperature. In case of large outer rotor BLDC motors, which are usually used for electric scooters, this traditional procedure may take many hours to complete, and is very complicated. *For several years, an innovative motor tester of MEA Testing Systems Ltd. is on the market. This testing system avoids any temperature confusion by testing a motor at constant temperature over the entire speed range. The test procedure is very fast, and gives the full load performances, including PWM current, voltage, torque, and driver efficiency, from stall up to no load. *During the test procedure, the motor is freely accelerated from stall to no load speed. The load of the motor is only the predetermined inertia of the rotor. From the moment of inertia and the acceleration, the torque of the motor is calculated and, also, the power output over the whole speed is given. Since the entire measuring time, depending on the motor size, is usually less than one second, the motor has no time to warm up. It remains at room temperature.

Dual Shaker Testing
NTS has a number of facilities capable of conducting dual shaker testing, vibration testing utilizing multiple electrodynamic exciters, for the evaluation of large payloads.Once such example was conducted as part of the test program for NASA’s Lunar Atmosphere and Dust Environment Explorer or LADEE. NTS worked with NASA’s Ames Research Center for simulated environmental testing of the LADEE observatory which included dual shaker vibration.Vibration testing on the observatory was conducted utilizing the NTS Santa Clarita facilities tandem Ling B-340 electrodynamic exciters. These exciters allow either dual shaker vibration testing, or in the case of the LADEE observatory tests, they minimize the test set-up time. The electrodynamic exciters were staged with one in the thrust axis and the other set-up for lateral axes vibration. This dual shaker set up allowed for a quick transition from one test to the other. During the tests, the vibration test lab was maintained at a class 10,000 cleanliness level.

Long Term Test Kit
When long term electro-chemical tests (>1000 hours) are run to monitor the cell degradation at the cathode for example, it is important to avoid any contaminant in the gas flow rate.Inconel 601 flange equipped with alumina housing and alumina tube to feed the gas to the electrode during long term test (>1000 h)Typical poisoning is coming from the chromium contained in the steel tubing. The volatile chromium species (Cr6+) will flow into the cathode (with the air) and thanks to the intake of electrons at the electrode, the chromium ion will transform to chromium oxide and be deposited at the cathode triple point. In such a case, the long term test kit is used. The Inconel 601 flange is equipped with an alumina housing (>96 % Al2O3) and the air (or other gas) is led through an alumina tube. The long term test kit is fully compatible with other functionalities proposed with the Open Flanges™ test Set-Up as the integrated steamer or the small pellet test kit. The long term test kit can be implemented on the fuel, on the air or on both sides.
