Marine bronze level sensor with a submersible construction for reliable performance in challenging seawater intake channels.
The SWL submersible level sensor is purpose-built for the demanding conditions found in seawater intake channels. These critical infrastructures require robust instrumentation capable of withstanding the corrosive nature of seawater while providing accurate and reliable level measurements. The SWL sensor excels in these environments due to its specialized design and construction.
One of the primary challenges in seawater intake channels is the highly corrosive nature of the water. The SWL sensor directly addresses this with its marine bronze (CA104) housing. This material is specifically chosen for its exceptional resistance to corrosion in saltwater environments, ensuring the sensor remains structurally sound and functional even after extended exposure. This longevity translates to reduced maintenance needs and a lower total cost of ownership, crucial factors for operators of seawater intake systems.
Deployment and maintenance in intake channels can be complex. The SWL sensor simplifies this process with its submersible design. The sensor can be easily lowered into the channel, reaching the required measurement depth without the need for complex installation procedures. This ease of deployment is further enhanced by the inclusion of a 15-meter PUR cable. This cable offers excellent flexibility, allowing it to navigate the contours of the channel, and its robust construction resists damage from abrasion or contact with channel walls. The IP68 rating of the cable provides complete protection against water ingress, ensuring reliable signal transmission even when fully submerged.
Accurate level measurement is essential for efficient operation of seawater intake channels. The SWL sensor provides this accuracy through its vented gauge pressure measurement principle. This method ensures that the sensor readings are compensated for atmospheric pressure changes, which can influence the water level in open channels. The venting is facilitated by a small tube within the cable, allowing the sensor to accurately reflect the true water level even with fluctuating weather conditions.
