We see from your search that you're looking for information on the term "Pressure Rating",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Sensors suit mobile applications from
Parker Hannifin, which we summarised at the time by saying "IQAN sensors are mounted in tough stainless steel or plastic housings, complete with all signal conditioning electronics and are protected against shock, vibration and electro-magnetic
interference".
A few weeks before,
we featured the news release Tube connectors are passed fit for military duty from
Parker Hannifin Instrumentation Products Division: "High pressure fluid connectors can now be specified for surface and submarine vessel pipework applications".
In May 2007, we covered the news from Plast-O-Matic Valves
concerning its Plastic Gauge Guard
- take a look at Seals hold 17bar pressures
which says: "Gauge Guards, also known as diaphragm seals or instrument isolators, are designed to protect gauges and other instruments from corrosive liquids".
Take a look also at the news release from Charcroft Electronics, Pressure sensor is made for HVAC applications,
as well as Sensor overcomes electrical noise from Sensata Technologies,
and Conductivity sensor gets measure of evaporation from ProMinent Fluid Controls (UK).
