    Hardness Testing in Materials Science and Engineering

    In the field of materials science and engineering, hardness testing plays a critical role in assessing a material's resistance to deformation. This property directly influences its durability, wear resistance, and overall performance in a wide range of applications. Understanding a material’s hardness is key to determining its suitability for specific functions.

    The most commonly referenced hardness tests in material datasheets are Rockwell, Brinell, and Vickers. Among these, the Rockwell method is the most widely used due to its speed and simplicity, particularly in industrial settings. The Leeb and Knoop methods are more specialised and are less frequently cited in standard datasheets, as they are typically used in specific testing conditions and for particular applications.

  • Ionizing Radiation

    Ionizing radiation is a form of energy that is capable of ionizing atoms and molecules, which means that it has enough energy to remove electrons from atoms, leaving them electrically charged. There are three main types of ionizing radiation: gamma radiation (γ), beta radiation (β) and X-rays.

    Gamma Radiation (γ):

    Gamma radiation is a form of high-energy electromagnetic radiation. Gamma (y) radiation is emitted by atomic nuclei during nuclear transition processes, such as radioactive decay.
    Gamma waves have no mass or electrical charge. And due to their high energy, gamma waves have the ability to penetrate deeply into materials, requiring significant thicknesses of concrete, lead or other high density materials to stop them.
    Gamma waves are used in several applications, including medicine (such as radiotherapy for cancer treatment), sterilization of materials, detection of flaws in materials, among others.

    Beta (β) radiation:

    Beta radiation (β) consists of electrons (β-) or positrons (β+), which are emitted by unstable nuclei during radioactive decay processes. Beta electrons are lighter than Gamma rays and, therefore, are less penetrating and can be blocked by materials such as metal plates or even clothing.

    Positrons are the antiparticle of electrons, and when they meet frequent electrons, they annihilate each other, releasing energy in the form of Gamma radiation. Beta radiation is often used in medicine, in applications such as cancer treatment and diagnostic imaging (such as positron emission tomography - PET scan).

    X ray:

    X-rays are a form of high-energy electromagnetic radiation, with wavelengths shorter than visible light. They are produced when high-energy electrons are abruptly slowed down or when electronic transitions occur in atoms.
    X-rays have greater penetrating strength than Beta radiation, but less than Gamma radiation. X-rays are widely used in medicine for diagnostic imaging, such as radiographs, fluoroscopy and computed tomography (CT scan), as well as in other areas such as airport security inspection, industrial quality control and in scientific research.
    In summary, these three types of ionizing radiation have different characteristics and applications, but they all present potential health risks and must be used with care and appropriate precautions.

  • Sound Meters & Decibel...

    From noisy nightclubs to loud manufacturing facilities, EMI LDA decibel meters are used to test whether a sound level exceeds levels established by municipal or national laws. Occupational safety and health standards for a reliable sound meter (commonly called a dB meter or noise meter) to determine an acceptable noise level with and without hearing protection. For on-the-person occupational sound measurement, EMI LDA noise dosimeter selection offers options for datalogging personal exposure to excessive sound levels.

  • Tachometers

    Pinpoint accuracy combined with measurement versatility. Tachometers are fast and accurate instruments utilizing laser or contact to measure rotational and linear speeds. Equipped with a laser and a range of contact adapters, they are versatile instruments that suit a wide range of applications. Having a compact design, they can be operated with just one hand and are supplied in a sturdy carrying case. The read out could be (km/h, RPM, meter per minute, liter per second ...).

    EMI LDA has a complete line of digital and programmable timers that suit different processes. It can be used to control the sequence of an event or process. Our timers can be mechanical, electromechanical and digital.

  • Transmitters

    What is a Transmitter?

    A transmitter is a device that converts a physical quantity (such as temperature, pressure, or position) into a standard signal (usually electrical or digital), enabling remote monitoring, control, or data logging.

    It is an essential component in automation, instrumentation, and telecommunications systems.

    General Operation

    1. Primary sensor: detects the physical variable (e.g., thermocouple for temperature).
    2. Transducer: converts the variable into a proportional electrical signal.
    3. Signal conditioning: amplification, filtering, etc.
    4. Final conversion: to a standardized signal (e.g., 4-20 mA, 0-10 V, digital).
    5. Transmission: to a controller, logger, or SCADA system.
