These sensors for very high pressures are made from treated and aged stainless steel.
They are completely machined from a single piece of material, offering excellent qualities of robustness, endurance and resistance to corrosion.
The pressure-sensitive part, fitted with a bridge of semi-conductor (800 series) or metal (850 series) piezo-resistive gauges, gives them very good fatigue resistance.
The conical metal/alloy metal pressure connection with 2 inverted screw threads provides excellent vibration resistance.-
