Advanced Sensing Technology At the core of the PRECISE sensor is PRESENS’ patented tubular sensing element well proven in subsea oil and gas applications for many years. Our piezoresistivesensors are distinguished for their reliability robustness long-term stability and high fi eld accuracy. This is due to the unique features of the sensing element: Silicon Si single crystal structure: • Minimizes errors due to thermal and mechanical hysteresis • Prevents long-term drift due to ”creep” Tubular design: • Mechanical decoupling of sensing area eliminates error due to mounting stress Operation in compressive stress: • Extreme tolerance to over-pressure and pressure spikes Piezoresistive resistor bridge: • Extremely stable • Pressure and temperature measured simultaneously Unique Pressure Module Design • A thick isolation diaphragm improves protection against harsh environments • A reduced oil volume decreases thermal errors • A reduced oil volume improves protection against damage caused by transient step changes in pressure Dimensional Drawing all dimensions in mm Protective diaphragm Hydraulic oil Sensing element Die attach Glass feed throughs Sensor housing Gold plated pins
