What is Polymer Absorption Sensor Technology (PAS)?
How does PAS Work?
- Absorption: When the target fluid contacts the polymer, the polymer tends to absorb it. This absorption results in a noticeable change in the polymer, often swelling or expanding.
- Signal Generation: This change is detected in various ways. For some PAS systems, the swelling of the polymer might complete an electrical circuit, triggering an alarm. Optical properties might change in others, allowing for a light-based detection system.
- Communication: Once a change is detected, the system communicates this change, either by sending an electronic signal, lighting up an indicator, or triggering an alarm.
Application in Industrial Leak Detection Cables
- Precision: PAS-enabled cables can precisely detect the leak's location.
- Versatility: Different polymers detect various fluids. This flexibility allows industries to deploy them in diverse environments, from oil pipelines to water reservoirs.
- Quick Response: Due to the polymer's immediate physical or chemical response, PAS provides almost instantaneous detection, ensuring minimal damage from unnoticed leaks.
- Durability: Polymers used in PAS are often chosen for their robustness and longevity, ensuring the cables remain functional without frequent replacements or maintenance.
