The PR871 sensor, designed for very high pressures, is made from treated and aged stainless steel.
It is 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 piezo-resistive metal-gauge bridge, provides excellent fatigue resistance.
The conical metal/alloy metal pressure connection with 2 inverted screw threads provides excellent vibration resistance.
