basic information
Differential pressure gauge that uses two Bourdon tubes to measure and indicate pressure differences at two locations. 【Features】 ○ Thanks to a unique overpressure prevention mechanism, there is no need to worry about instrument damage caused by overpressure due to improper operation of the bypass valve (equalizing valve), which was previously essential, allowing for safe use. ○ Depending on the usage conditions of the specified fluid, it is also possible to manufacture parts in SUS type or isolation diaphragm type. ○ Two types of cases are available: indoor type with a flange and outdoor type with dustproof and drip-proof structure. ○ As a special specification, it can also be used as a flow meter by indicating the liquid level of a sealed tank through a conversion scale or by converting flow velocity. ○ Size: φ150/φ200 ○ Shape: DPGN type (wall-mounted), DPGD type (embedded) ○ Standard operating pressure ranges from 0 to 0.1 MPa to 0 to 8 MPa (for liquid-contact SUS specifications, standard up to 3.5 MPa). ● 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.
