"Templug" is a small screw-like component that can be installed in movable parts or intricate areas where conventional temperature measurement devices are difficult to use. It is installed by cutting a tap into the movable parts of the engine (such as pistons and blades) and operated in a screwed-in state. After a certain exposure to temperature, it can be removed and analyzed by the manufacturer to determine the maximum temperature reached at the installation site. The analysis at the manufacturer involves measuring the hardness changes of the screw due to the quenching effect and cross-referencing with a database. [Features] ■ Analyze the actual maximum temperature reached in intricate areas and small components where traditional temperature measurement methods are challenging! ■ The measurable temperature range is from 100°C to 850°C! * The minimum measurable temperature may vary depending on the maximum temperature exposure time. Please consult us.

This is a high-precision temperature control valve using a wax-filled actuator. The actuator utilizes the powerful force generated by the expansion and contraction of the enclosed wax as it changes state between solid and liquid due to temperature. Since it operates without using electricity, it is maintenance-free and excels in reliability and energy efficiency.

The precision gold-plated bellows contact springs from Servometer Inc. (USA) demonstrate high reliability in areas where issues arise with the repeatability of springs and stress due to tolerances, vibrations, and thermal expansion. The flexibility of the springs minimizes shocks and vibrations in dynamic applications while maintaining contact. The spring constant is very low, allowing for production at a required stress of 44.49g per mm. This enables designs for contacts that use delicate components and materials. The product is made with electroless nickel and is gold-plated to enhance conductivity. Most end caps are designed to fit into pins or pockets, allowing for connections to other components without soldering. **Features** - Very low self-inductance - Very low DC resistance - Very low insertion loss - High repeatability of the spring - No need for large forces to maintain contact at two points - Can be used for electrostatic discharge (ESD) protection as needed

For precise motion control, a more accurate positioning system is required. Such systems need couplings that have torsional strength, accurately transmit rotational positions, and adjust for misalignment on the shaft side. This product is a precision electroplated nickel bellows coupling that achieves flexibility and compatibility with miniature sizes to meet such demands. Its high flexibility on the sides makes it less susceptible to lateral interference, while also possessing torsional rigidity. It is essential for critical applications such as resolvers, encoders, servos, motion control devices, and computers. 【Features】 ■ Non-backlash ■ Very low elasticity and does not twist ■ Maintains a constant rotational speed during 360-degree rotation ■ Less susceptible to lateral interference on bearings ■ Functions to absorb vibrations ■ Compatible with shaft diameters from φ2mm ■ Accommodates large shaft runout *Please feel free to inquire about standard sizes/model numbers of manufacturer stock items. Custom orders are also available.

The miniature bellows from Servometer are capable of achieving a very thin bellows plate thickness through an electrodeposition process, making them both "miniature-sized" and "highly flexible."

Eliminates concerns about dust and debris that can cause contamination, while maintaining an extremely low leak level.

This is an electric oil mist collector that is optimal for capturing submicron-sized oil mist. Releasing petroleum-based oils and chemical synthetic oils into the atmosphere in factories can potentially cause adverse effects on human health and lead to air and soil pollution. This product effectively removes submicron-sized oil mist, which is difficult to eliminate with mechanical filters or centrifuges, using an electric method with high efficiency. 【Features】 ■ High-efficiency removal of high-concentration oil mist - High-concentration mist exceeding 1000 mg/m3 can be removed with high efficiency! The collected mist is liquefied on the dust collection electrode and can be recovered from the lower drain port. ■ Significant savings on running costs - High-efficiency mist separators are generally costly and require frequent maintenance to prevent pressure loss due to filter clogging. Unlike self-priming models, this product does not have an intake fan and has no moving parts, resulting in a power consumption of less than 50W! ■ Compact design focused on maintainability - The internal cell is stored in a pull-out style, making it easy to remove during maintenance! The inspection door can also be easily opened and closed without tools! ■ Zero waste design - Unlike filter systems, there is zero waste!
