06 May 2025 click : 13In underwater operation scenarios, the performance and cost of safety light curtains are key considerations. When compared with traditional waterproof light curtains, the SCE NB underwater safety light curtain demonstrates significant advantages.
In terms of performance, the SCE NB underwater safety light curtain has a protection rating of IP68, allowing it to operate stably for a long time underwater at great depths. In contrast, most traditional waterproof light curtains have a protection rating of only IP65 or IP66, making them difficult to cope with deep underwater environments. The SCE NB has a light-resistant feature, enabling it to accurately detect under complex underwater lighting conditions. Traditional waterproof light curtains are easily interfered with by light, leading to misjudgments. At the same time, the SCE NB supports both NPN and PNP modes, making it adaptable to a variety of devices. Traditional waterproof light curtains have a single output mode and poor compatibility.
Regarding cost, although the initial purchase cost of the SCE NB underwater safety light curtain is slightly higher, from a long-term usage perspective, its high stability and long service life significantly reduce the frequency of maintenance and replacement, and decrease the costs of shutdown and repair. Due to their performance limitations, traditional waterproof light curtains frequently malfunction, resulting in high post-maintenance costs. Overall, with superior performance and a lower cost over its entire life cycle, the SCE NB underwater safety light curtain becomes an ideal choice for underwater operation safety protection, bringing higher economic benefits and safety guarantees to the industry..jpg)
To make it more convenient for you to watch, we have written the key data into a table.
| Comparison Items | SCE NB Underwater Safety Light Curtain | Traditional Waterproof Light Curtain |
|---|---|---|
| Protection Rating | IP68, can be stably used in deep water for a long time | Mostly at IP65 or IP66 level, difficult to cope with deep underwater environments |
| Light Resistance Performance | Has the light-resistant feature and can accurately detect under complex underwater lighting conditions | Easily interfered by light, resulting in detection misjudgment |
| Output Modes | Supports both NPN and PNP modes, adaptable to a variety of devices | Single output mode, with poor compatibility |
| Initial Purchase Cost | Slightly higher | Relatively lower |
| Maintenance Frequency | Low due to high stability | High due to performance limitations and frequent failures |
| Replacement Frequency | Long service life, low replacement frequency | Prone to damage, relatively high replacement frequency |
| Shutdown and Maintenance Cost | Low, as the low maintenance and replacement frequencies lead to short shutdown time | High, as frequent failures result in long shutdown and maintenance time |
| Total Cost of Ownership | Relatively low overall, with good long-term economic benefits | Relatively high overall, with high post-maintenance costs |
