basic information
This is an introduction to the contact switch type electric contact differential pressure gauge handled by Kobata Instrument Manufacturing, which manufactures and sells pressure gauges and differential pressure gauges. 【Features】 ○ A contact-type electric contact is provided on the pointer of the Bourdon tube type differential pressure gauge, allowing for the opening and closing of the electric circuit simultaneously with differential pressure measurement, making it ideal for alarms during abnormal pressure. ○ Available in single contact type (upper limit, lower limit) and double contact type (upper and lower limits). ○ By rotating the setting knob located at the center of the indicator, it can be easily set to the desired pressure from the outside. ○ Electrical wiring is connected to the terminal terminals inside the terminal box. ○ Sizes: φ150, φ200 ○ Shapes: DPGN type (wall-mounted), DPGD type (embedded) ○ Standard operating reference pressure ranges from 0 to 0.1 MPa to 0 to 8 MPa (standard for liquid-contact SUS specifications is up to 3.5 MPa). ○ Maximum differential pressure scale is 1/3 or 1/5 of the standard operating 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 founder, Kyuemon Kobata, established Kobata Instrument Manufacturing Co., Ltd. in the Utsubo area of Nishi Ward, Osaka. He anticipated the wave of industrialization that would follow and focused on the Bourdon tube pressure gauge, which at the 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 we have produced pressure gauges under the "Anchor Mark" brand, gaining popularity in 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. Today, we handle a wide range of measurement and control devices, including pressure, differential pressure, liquid level, temperature, and flow, and we continue to strive day and night to be a company that can broadly assist everyone with their measurement and control needs.
