YP patch-pressure gauges for measuring the copper and copper alloy non-corrosive, non-crystalline, high-viscosity of liquid or gas pressure. Seismic patch-patch-pressure gauge with a general pressure gauges the performance of medium-Pulse at the same time, environmental impact load and vibration-resistant properties. Decay resistance patch-pressure gauges for measuring corrosive to a certain extent, viscosity, no crystallization of liquids and gases pressure. Seismic decay resistance patch-pressure gauge, pressure gauges and decay resistance patch-patch-pressure gauges and seismic characteristics of the two. YP-150L膜片压力表 |
