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.
Instruments implementation of the standards: JB/T8624-1997 Protective shell Instrument Rating: IP64 Seismic patch-pressure gauges and decay resistance of the Anti-Seismic patch-pressure gauges working environment for the GB4439 performance under the VH4 level. The use of temperature: patch-pressure gauge, the decay resistance patch-pressure gauge -40 ~ 70 ℃. Seismic patch-pressure gauge, the decay resistance Seismic patch-pressure gauge: irrigation for glycerin filled when -5 ~ 55 ℃, Irrigation for the silicone oil filled at -25 ~ 55 ℃.
