This pressure gauge is designed in accordance with JPI standard. The standard specifies bourdon tube pressure gauge specification and performance to suit for Petroleum industry (including Petroleum refining, Petrochemical and natural gas industry).

• ・Highly durable

• Vibration 25Hz 0.75G for 200 hours within ±1.0%F.S.

To maximize performance, select full scale pressure range to indicate normal operating pressure which comes to 　conditions below.

For constant pressure　: The maximum operating pressure should not exceed three-quarters of the full-scale range.

For fluctuating pressure: The maximum operating pressure should not exceed two-thirds of the full-scale range.
