Choose from our selection of mpa pressure gauges, including pressure gauges, vibration-resistant pressure gauges, and more. Same and Next Day Delivery.

gauge（测量）的缩写；A代表的是绝对压力，absolute pressure；绝对压力=表压+0.1MPa。 绝对压力和表面压力的关系是表压+当地的大气压=绝对压强，例如：表压0.1mpag，绝对压强就等于0.1+0.1=0.2mpaa一个大气压为0.1013mpa。

我们的压力表（机械压力测量仪表）可满足表压、绝压和差压测量应用，并久经数百万次的实践检验。我们提供采用波登管、隔膜或膜盒技术的测量系统，能针对客户的不同应用提供解决方案。压力表量程从0 ... 0.05 kPa到0 ... 600 MPa，显示精度可达0.1 %。

2019年10月25日 · 压力容器压力管道图纸经常会看到单位MPa（G），MPa（G）表示表压，也就是压力表指示的压力，不是绝对压力，而是相对压力。 另外还有MPa（A），代表绝对压力。

HydraCheck MPa pressure gauges are instruments used to measure and display the pressure within hydraulic circuits. These analog gauges are essential for monitoring system performance and ensuring operational safety. They feature robust construction to withstand the high-pressure environments of hydraulic systems.

Pressure gauges range from 0 to 1.5 MPa for a variety of types, including specialized gauges: oil-free/external parts copper-free, clean series and gauge with pressure switch. The pressure differential at the inlet and the outlet of compressed air equipment can be viewed at a glance on the pressure differential gauge.

Provide accurate pressure measurements in industrial applications, monitoring vacuum and positive pressures up to 15 000 psi, 1000 bar, or 100 mpa. Locate detailed product information, including materials of construction, pressure and temperature ratings, options, and accessories.

Mpa(g)系指表压. Mpa(a)系指绝对压力. 绝对压力和表压的关系是表压+当地的大气压=绝对压力

A concrete testing lab uses a digital gauge to measure compressive strength in MPa. An engineer checks the hydraulic pressure in a lift system with a high-range MPa-rated gauge. An oil refinery uses pressure transducers to constantly monitor pipe pressure in MPa for safety compliance.
