Advantages and Applications of Linear Variable Differential Transducers by Ono Sokki

 

Linear variable differential transducers (LVDT) are sensors for measuring linear displacement, position, or motion. They are non-contact transducers, meaning they do not have physical contact with the object being measured and therefore do not cause wear or damage. LVDTs consist of a stationary coil assembly and a movable core made of a magnetic material. When the core is displaced along the axis of the coil, it induces a voltage in the coil windings that is proportional to the distance of the core's displacement from the center position.

Linear variable differential transducers

It can be designed with different measurement ranges and sensitivities to suit various applications. They are typically used in environments where high-accuracy measurements are required, such as in manufacturing, aerospace, and defined industries, as well as in laboratory and scientific research settings.

Linear variable differential transducers have several advantages over other types of displacement sensors. They are rugged, durable, and can operate in harsh environments and extreme temperatures. They are also highly accurate, with the ability to provide precise measurements down to the sub-micron level. Depending on the application requirements, they are versatile and can be configured to output various signal types, including AC voltage, DC voltage, and digital signals. Overall, they are widely used for measuring linear displacement and position in various applications where high accuracy and durability are essential.

 

How do linear variable differential transducers work?

 

• It consists of a stationary coil assembly and a movable core made of a magnetic material.
• The stationary coil assembly consists of a primary coil and two secondary coils wound on a cylindrical former. An AC voltage source energizes the primary coil, which creates an alternating magnetic field in the core.
• The two secondary coils are positioned symmetrically on either side of the primary coil. When the core is displaced along the axis of the coil, it changes the magnetic coupling between the primary coil and the secondary coils, which results in an output voltage proportional to the distance of the core's displacement from the center position.
• The output voltage of this device is a differential voltage between the two secondary coils, which is proportional to the displacement of the core. The amplitude and phase of the output voltage depend on the core's position relative to the center position of the coil.
• Typically, a signal conditioner processes the output voltage by amplifying, filtering, and linearizing the output signal to produce a calibrated and stable output voltage or current proportional to the displacement.

Advantages of Linear Variable Differential Transducers

Experience Superior Noise Monitoring with Ono Sokki's Sound Level Meter

 

Noise monitoring is the process of measuring and analyzing noise levels in a specific environment or location. It is important for various reasons, such as protecting public health, ensuring compliance with noise regulations, and reducing noise pollution. Several tools and technologies are available for noise monitoring, such as noise level meters, dosimeters, and environmental noise monitoring systems. These devices measure dB meter noise levels and provide real-time monitoring and data logging capabilities.

Importance of Noise Monitoring

Noise monitoring is important for several reasons, including:

• Protecting Public Health: Exposure to excessive noise can cause hearing loss, sleep disturbance, cardiovascular disease, and other health problems. Noise monitoring can help identify areas where noise levels are high and take measures to reduce exposure and protect public health.
• Compliance with Regulations: Many countries and municipalities have noise regulations to protect citizens from excessive noise exposure. Noise monitoring can help ensure these regulations are followed and prevent noise-related legal issues.
• Identifying Sources of Noise: Noise monitoring can help identify the sources of noise pollution, such as traffic, construction, and industrial activities. This information can then be used to develop noise reduction and mitigation strategies.
• Planning and Designing: Noise monitoring can be used in a project's planning and design phases, such as building a new highway or residential development. This can help identify potential noise issues early on and take measures to minimize their impact on the community.

Regulatory Requirements for Noise Monitoring

Ono Sokki's maximum permissible exposure limit to noise is 90 dB (decibels) for all workers. Employers must implement a hearing conservation program when workers are exposed to an average noise level meter of 85 dB or higher for an eight-hour shift.

Best Practices for Noise Monitoring

• Select the appropriate noise monitoring equipment: Different environments require different types of noise monitoring equipment. Choose the appropriate equipment based on the type of noise being monitored, the location and environment, the duration of monitoring, and any regulatory requirements.

• Calibrate the equipment: Ensure the noise monitoring equipment is properly calibrated and maintained according to the manufacturer's recommendations. Conduct a site survey: Before starting the noise monitoring, conduct a site survey to identify potential sources of noise pollution and determine the best locations to place the monitoring equipment.

• Conduct the monitoring at appropriate times: The monitoring should be conducted when the noise levels are highest, such as during peak traffic hours or when industrial activities are at their highest.

What types of instruments are used for Noise Monitoring?

• Sound Level Meter: They are portable instruments that measure sound pressure levels in decibels (dB). They typically consist of a microphone, amplifier, and display unit. The sound level meters can measure noise metrics and provide real-time measurements and data logging capabilities.

• Noise Dosimeters: Noise dosimeters are wearable instruments used to measure personal noise exposure over some time, such as a workday or shift. They are typically worn on the worker's shoulder or belt and measure noise exposure in a dB meter based on industry standards.

• Integrating Sound Level Meters: They are advanced and can measure and integrate noise levels over time, such as an entire workday or week. They can provide detailed information about noise exposure levels, such as dose and exposure time, and are often used in occupational noise exposure monitoring.
