  • Mechanical Testing Services

    National Technical Systems

    The physical and mechanical testing of a product comprises a critical part of the product and development process. Applied physical force such as vibration, shock stresses, and strain can reveal the inelastic behavior of the material. Mechanical testing allows the product developers to understand the product better, identify vulnerabilities, and establish stronger quality control. Mechanical testing employs a variety of strength tests that can determine the suitability of a material or component for the intended application. It measures characteristics such as elasticity, tensile strength, elongation, hardness, facture toughness, impact resistance, stress fracture, and the fatigue limit.

  • Steam Aging Test Chambers

    Dongguan Amade Instruments Technology Co., Ltd

    Steam aging test chamber is a climatic test machine used to judge the products performance to resist extreme circumstance under high temperature, high humidity and high pressure during the transportation, storage and usage. The principle is very simple, water in the tank is heated turning into steam to form a simulated test environment under specified temperature and humidity. Specimens are placed into the drawers of machine to carry out test lasting for preselected time. It is applicable to electronic connectors, semiconductor IC, transistor, LCD, diodes, resistances etc.

  • Gunn Diodes

    Teledyne Lincoln Microwave

    The Gunn diode is the best known and most readily available device in the family of transferred electron devices (TED). They are employed as DC to microwave converters using the negative resistance characteristics of bulk Gallium Arsenide (GaAs) and only require a standard, low impedance, constant voltage power supply, thereby eliminating complex circuitry. Teledyne Lincoln Microwave’s DC1200 series of GaAs Gunn diodes is designed for operation at fixed frequency (determined by the oscillator cavity) within a specified band under CW or pulsed conditions.

  • 20Hz Injection Kit Monitoring System

    Signals & Systems India Private Limited

    The Display used to monitor the 20Hz and 50Hz current passing through NGT transformer. This could help to monitor the stator earth fault and could record the current every minute. The current shall be displayed in milliamps for both 20Hz and 50Hz. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. The current can be measured using clamp-on CT which would be clamped between load resistor and NGT. It gives an indication of the current values are lower or higher than the set threshold.
