Project Summary
Emerson-Rosemount measurement instruments and accessories are currently limited in available display sizes and display technology. This new product is an accessory to new and installed measurement instruments and will enhance the user experience, and reduce installation time for field upgrades.
Design Goal
Develop a loop powered (HART 4-20mA) display by selecting the electrical and mechanical components, designing a custom plastic and machined housing, develop an embedded electronic system, and develop functionality for this concept to work across all Emerson-Rosemount measurement products. A successful project will reduce unit field upgrade time, incorporate a modernized and enlarged display, and meet the design requirements of being a low power device while maintaining the mechanical flameproof/explosion standards of current Emerson-Rosemount devices.
Design Constraints
- Incorporate an E-Ink display that can be read from at least 5 ft away.
- Material cost is less than $40 in an annual quantity 10,000.
- Comply with current vibrational and temperature requirements.
- Support future compliance of flameproof/explosion-proof requirements according to IEC, CSA, and FM Standards.
- Conform to IP66 sealing standards.
- Operate on a minimum and maximum HART loop current of 3.4 mA and 23 mA.
- Thread into existing threads of Rosemount 3051 pressure transmitter.
