Finding an off-the-shelf solution that works well for your design requirements is not always possible. A recent project for a customer who makes equipment and wiring for process heat maintenance posted an interesting challenge. The company’s application required a rugged, economical HMI (human-machine interface) that operated to -30°C. This application is problematic because most HMI’s are based on TFT LCDs that cannot be operated without damage below 0°C without a heating system. In this case, Sealevel’s engineering team overcame this challenge by designing an LCD-based HMI capable of operation below 0°C without heaters.
This particular application required use of Sealevel’s engineering expertise in the areas of:
- Design Specification and Project Management
- Electrical Design
- Software Design
- Product Compliance and Certifications
- Environmental Stress Screening (ESS)
