Its Mean Time Between Failures (MTBF) is estimated to be around 140,000 hours. This long – term reliable operation has minimized production disruptions, saving the refinery approximately $90,000 in potential losses due to downtime.
- Easy Integration: In an automotive manufacturing plant’s upgrade project, integrating the HONEYWELL 8937 – HN into the existing Honeywell – based PLC system took only 4 days. Its well – defined interfaces and compatibility with Honeywell’s systems allowed for seamless connection with other components in the production line control system.
- High – speed Data Processing: With a data processing rate of up to 2500 samples per second for analog inputs, it can quickly analyze and respond to changes in the industrial process. In a power generation plant, this high – speed processing enabled precise adjustment of turbine speed based on load changes, improving power generation efficiency by 13%.
4. Application Areas and Application Cases
- Application Areas: The HONEYWELL 8937 – HN is widely used in the manufacturing industry, including automotive, electronics, and machinery manufacturing. In the energy sector, it can be found in power plants, oil refineries, and gas – processing plants. It also has applications in the water treatment industry for controlling water treatment processes, and in the food and beverage industry for regulating production lines.
- Application Case: In a large – scale food and beverage production facility, the HONEYWELL 8937 – HN was used to control the bottling process. It received real – time data from sensors monitoring the liquid level in the bottles, the capping torque, and the conveyor belt speed. Based on this data, it adjusted the filling and capping machinery. As a result, the number of defective bottles decreased by 25%, improving the overall product quality and production efficiency.
5. Comparison with Competitors
Compared to similar products in the market, the HONEYWELL 8937 – HN offers a higher level of reliability, as indicated by its long MTBF. Some competing products may have a shorter lifespan under similar operating conditions. In terms of integration, its excellent compatibility with Honeywell’s systems gives it an edge. It can be integrated more easily and quickly, reducing the time and effort required for system implementation. Also, its high – speed data processing capabilities provide a competitive advantage in applications where rapid response to process changes is crucial. Some competing products may have slower data processing speeds, which could lead to less – precise control.
6. Selection Suggestions
- Compatibility: Ensure that your existing PLC system is a Honeywell system or has the necessary compatibility with the HONEYWELL 8937 – HN. Check the communication protocols, voltage requirements, and interface types of your current setup. If you plan to expand or upgrade your system in the future, consider the long – term compatibility as well.
- Installation Environment: Take into account the operating temperature and humidity of the installation location. If the environment is close to the extreme limits of the specified range, proper measures like cooling, heating, or humidity control may be necessary. Also, be aware of potential electromagnetic interference and ensure proper shielding.
- Budget: While the HONEYWELL 8937 – HN offers high – quality performance, compare its cost with your budget. Consider the long – term cost – effectiveness, including potential savings from reduced production downtime, increased efficiency, and lower maintenance costs.
7. Precautions
- Installation: Follow the detailed installation instructions provided by Honeywell. Ensure proper grounding to prevent electrical interference. When connecting the input and output interfaces, make sure the connections are secure to avoid signal loss or incorrect operation.
