Engine Test Adapters
-
Atec has built test adapters for a wide variety of engines from high bypass fan engines to small APU engines. Testing a new engine type in your existing jet engine test cell can be challenging, and upgrade modifications will be needed. Atec does not view an adapter as just a mechanical weldment that simply mates the engine to the aeroengine thrust stand. Our engineers realize that additional items will be needed in the facility to insure total project success. During the planning phase, Atec engineers can visit your existing facility and/or review videos to make a comprehensive assessment of the integration needed to add a new engine type to your testing facility. Atec can perform airflow, acoustics, FEA and sub systems analyses to ensure that any new engine added to your jet engine test cell will have the proper capacity to perform properly. Vital Link’s current experience with advanced fighter engines test adapter kits further bolsters our expertise in high thrust engine test handling.

Three-Phase Transformer Winding Resistance Meters
TWA Standard Series
-
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, simultaneously with the measurement of tap changer motor current which helps with the detection of motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer (connected in a YN configuration). This can significantly shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.

Near Field Probes 30 MHz up to 3 GHz
RF2 set
-
The RF2 near field probe set consists of 4 passive near field probes for measurements in the development phase of the magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF2 set allow the step by step localization of interference sources of the RF magnetic field on assemblies. From greater distances the electromagnetic interference can be detected by RF-R 400-1 and RF-R 50-1 probes. The RF-B 3-2 and RF-U 5-2 probes with their higher resolution can more precisely detect the interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

LC/MS/MS Method Package For Short Chain Fatty Acids
-
Of the short-chain fatty acids produced by intestinal bacteria, acetic acid, propionic acid, and butyric acid are well known, and it has been reported that there are some connections between them and lifestyle-related diseases such as obesity and diabetes. Generally speaking, short-chain fatty acids are highly volatile and highly hydrophilic. This makes it dificult to perform LCMS analysis using a conventional reverse phase system. For that reason, this method package targets short-chain fatty acids (C2 to C5) that have been derivatized using 3-nitrophenylhydrazine (3-NPH). Through making settings for MRM transitions, it can be used for the simultaneous analysis (of 22 components), including organic acids related to the central metabolic pathways.
