Pressure Gauge
Business Overview
- Founded in 1896, specializing in the development, manufacture, and sale of pressure gauges from low to ultra-high pressure. Holding over 60% of the domestic market share in terms of sales.
- An instrument that converts the "pushing force" of air or liquid into pressure values, which can be read by the movement of an indicator. It does not require driving power and displays pressure in a form visible to the human eye simply by being installed. Operators can easily visually check the pressure values.
Core Technologies
Helical Type Bourdon Tube
Medium to high pressureThe helical type bourdon tube is equipped on a pressure gauge for high pressure measurements not supported on the C-type bourdon tube.
Spiral Type Bourdon Tube
Low to medium pressureThe spiral type bourdon tube is not require the internal mechanism used in general pressure gauges. For that reason, the measurable pressure range is limited, but the durability is ssuperior.
Type C Bourdon Tube
Low to medium pressureThe bourdon tube is the most important component of the mechanical pressure gauge. The Type C bourdon tube is the most commonly used shape,with a wide measurable pressure range and excellent accuracy and durability.
Bellows
Low pressureThe bellows is a thin cylinder element with deep bellows-like folds on the outer circumference. This method uses the displacement caused by applying pressure inside the bellows. It is also possible to measure differential pressure by applying pressure to the inside and outside of the bellows.
Capsule
Minute pressureThe capsule is made of two corrugated circular metal plates joined together, and the method involves applying pressure to the inside and utilizing the resulting displacement.
Diaphragm
Fine differential pressureThe diaphragm is an element made of a relatively flexible plate material with a fixed periphery. When pressure is applied, the center part bends, and this displacement is utilized.
Industry Details
Industrial processes
Key Areas
Compressor Power Plant Oil Refining Chemical Complex Vaccum Pump Agricultural MachineryIn chemical plants and complexes, various liquids and gases are supplied through piping. By installing pressure gauges, pipe ruptures and leaks can be prevented in advance, ensuring the safety of the facility. Additionally, measuring ressure inside tanks and storage containers helps monitor remaining quantities and contributes to reducing the risk of accidents such as explosions.
FA Pneumatic
Key Areas
Pneumatic EquipmentIn automated factory production lines, compressed air is used when machines and robots transport or lift objects. Pneumatic systems in packaging machinery and assembly robots need to operate at specified pressures, making it crucial to continuously monitor pressure with gauges. If the pressure supply becomes unstable, it can hinder the accurate functioning of the machines and potentially cause significant disruptions to production efficiency.
HVAC
Key Areas
Clean Room (Semiconductor, Pharmaceutical, Food) Building Air ConditioningEnsuring appropriate air flow measurement within ducts is deemed critical for maintaining adequate ventilation in residential spaces, securing proper airflow and detecting filter clogs through the measurement of minute pressure differences. This is essential in various settings such as offices, semiconductor manufacturing, pharmaceuticals, and food processing plants. Additionally, maintaining proper water pressure in household and building water supply systems not only ensures adequate provision of potable water but also contributes to reducing leaks from the piping system.
Semiconductor
Key Areas
Factory Piping Gas, Water, and Chemical SupplyIn the semiconductor manufacturing process, pressure measurement is essential when supplying "gas, chemicals, and ultrapure water." It contributes to enhancing the quality and stability throughout the entire semiconductor production process. This ensures not only a uniform gas supply but also appropriate pressure management, which helps protect the equipment. In particular, devices such as gas cylinders, which do not visually display their remaining contents, are frequently monitored using pressure gauges to check the residual amounts for various applications.
