basic information
Differential Pressure Gauge with Mechanical Contact Mechanism 【Features】 ○ Utilizes carefully selected Bourdon tubes, diaphragms, bellows, and micro-switches to detect and indicate differences in pressure through a unique mechanism. The micro-switch opens and closes when the desired differential pressure setting is reached in advance. ○ Compared to pointer contact types, it provides more accurate readings and exhibits excellent performance for alarm control due to its larger contact capacity. ○ Size: Dial diameter φ200mm ○ Contact capacity: AC 125V 15A ○ Ground: JIS-F880115C ○ Connection thread: P.F 3/8 ○ Accuracy: ±1.5% F.S ○ Normal reference pressure: MAX 0 to 1MPa ○ Differential pressure scale range: 1/20 to 1/5 of normal reference pressure ● For other functions and details, please contact us.

Company information
The Wright brothers first took to the skies, fulfilling humanity's dream of flight, about a century ago in 1903. Six years later, in 1909, our first founder, Kyuemon Kobata, established Kobata Instrument Manufacturing Company in the Utsubo area of Nishi Ward, Osaka. He anticipated the wave of industrialization that was to come and focused on the Bourdon tube pressure gauge, which at that time had few domestic manufacturers and relied heavily on imports. He conducted extensive research and successfully applied the techniques from his family's hardware manufacturing business to produce Bourdon tubes. In 2009, we celebrated our 100th anniversary, during which time our company has produced pressure gauges under the "Anchor Mark" brand, gaining popularity and being adopted across various industries, including shipbuilding. Since then, we have developed and manufactured numerous control devices, including pressure switches with unique mechanisms that utilize pressure measurement technology. Currently, we handle a wide range of measurement and control devices for pressure, differential pressure, liquid level, temperature, and flow, and we continue to strive day and night to become a company that can provide extensive support in measurement and control to all of you.
