Introducing devices for measuring the thermal diffusivity of sheet-like and plate-like materials, as well as thermal evaluation devices for fiber orientation distribution!

Introducing Bethel's thermal property measurement devices. The "Thermo Wave Analyzer TA33/35" is a measurement device for the thermal diffusivity of sheet and plate materials, capable of measuring the thermal diffusivity of functional materials. The "Thermal Microscope TM" has been commercialized through joint development with the National Institute of Advanced Industrial Science and Technology's Measurement Standards Division, allowing for measurements in micro-regions and thin films. Additionally, we offer the "Thermal Imaging Scope TSI," which visualizes thermal conduction paths using infrared cameras and lasers, as well as the "Fiber Orientation Evaluation System TEFOD." 【Features of the Thermo Wave Analyzer TA33/35】 ■ High freedom of sample shape ■ Dynamic range from organic films to diamonds ■ Anisotropy evaluation through measurements in horizontal and vertical directions ■ Evaluation of defects and irregularities through distribution measurements *For more details, please refer to the PDF document or feel free to contact us.

• Other measurement, recording and measuring instruments

Leave the measurement of the thermal conductivity of carbon fiber reinforced plastic (CFRP) to us.

Carbon fiber reinforced plastics (CFRP), used in electric vehicles, aircraft, satellites, and rockets, require precise knowledge of thermal conductivity. For instance, when used in electric vehicles, understanding thermal conductivity is essential for heating performance and battery thermal management. Changes in electricity consumption due to heating performance and thermal management significantly affect driving range. Similarly, when used in satellites and rockets in the harsh environment of space, it is necessary to understand thermal conductivity to ensure heat resistance performance. With Bethel, you can accurately measure the thermal conductivity of this carbon fiber reinforced plastic (CFRP).

Even thin and small samples, as well as samples with high thermal conductivity, can be measured!

We are also able to measure the thermal conductivity of conductive diamonds. Normally, diamonds are insulators, but by doping with boron, they can be made conductive, allowing for the creation of high-performance electrodes. This enables redox reactions that are impossible with electrodes made from other materials due to a wide potential window, and they can be used in harsh environments such as strong acids and strong alkalis, offering significant advantages. Personally, I am particularly interested in their potential use in the recycling of CFRP. The measurements will be conducted using the ThermoWave Analyzer TA35. [About the Samples] The samples this time have thicknesses of 30μm and 300μm, and with a sample size of 10mm x 10mm, it can be said that measurement with ordinary thermal conductivity measurement devices is nearly impossible. Measurement is only possible with the ThermoWave Analyzer. The 30μm thick sample is matte black with a smooth surface. The 300μm thick sample is also matte black, but its surface was slightly rough. However, this level of roughness has no effect on the measurements at all.

• Thermo-fluid analysis

Are you measuring the correct thermal conductivity of the thermal pad?

A thermal pad is a type of thermal interface material used for heat dissipation in CPUs and power devices. Due to its flexibility and relatively high thermal conductivity, it effectively reduces contact thermal resistance by filling the gaps between the heat sink and the device. Do you accurately understand the thermal conductivity of thermal pads? Thermal pads have elasticity, so their contact state changes with pressure. In other words, the effective thermal conductivity varies with pressure. Additionally, many materials exhibit temperature dependence in thermal conductivity, meaning that as the temperature increases, the thermal conductivity decreases. In this instance, we measured a commercially available thermal pad with a specification of 1.5W/mK. This is a soft type referred to as a soft thermal pad. The measurement device used is our steady-state thermal conductivity measurement device, the SS-H40.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who wish to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. You can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520" depending on the application and installation location. 【Recommended for such places!】 ☑ Entrance facing a busy corridor ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passages ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing, contributing to energy-saving by minimizing wasteful power consumption ● Equipped with a light touch function, allowing the door to open and close just by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.
