Advanced Sensing
Unique Pressure
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
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
