[EDN.716: Pressure Transmitter with All-Stainless Steel Housing and High-Visibility LCD]

• Wetted parts made of stainless steel
• Housing made of stainless steel
• Accuracy: 0.5%
• LCD with white backlight
• Explosion-proof rating: Ex d IIC T6

The EDN.716 series pressure transmitter features a rugged stainless steel housing and a white-backlit LCD display, offering excellent visibility and durability in harsh environments. This model is designed to be used in conjunction with the MDF series diaphragm (chemical) seals, enhancing its applicability for chemically aggressive and toxic media.

Constructed to resist corrosion and environmental intrusion, the EDN.716 is well-suited for demanding applications in petrochemical, refining, food and beverage, medical, pharmaceutical, and biotechnology industries.

The MDF chemical seal includes a diaphragm integrated between flanges. The wetted diaphragm parts can be customized using the following special materials to meet specific application requirements:

■ Teflon (PTFE) coated
■ Hastelloy C series
■ Titanium
■ Tantalum

The EDN.716's pressure sensor and internal electronics are developed and tested to the highest industrial standards, incorporating technologies for noise suppression, burst resistance, insulation, and surge protection. Developed through DAHO’s in-house engineering and quality assurance processes, each unit undergoes comprehensive final testing to ensure reliable analog and digital communication signal output.

Key Functional Features:

• RS485 digital communication
• 2 relay output channels with switch functionality

The product has undergone more than ten rigorous performance tests alongside leading domestic and global brands, to meet and exceed industry demands. It has also passed high-level EMC and EMI tests, ensuring stable performance under adverse conditions such as:

• High temperatures
• Electromagnetic noise
• Electrical surges and bursts

With integrated protective features, the EDN.716 is a reliable industrial-grade pressure transmitter, ideal for operation in a wide variety of challenging environments and applications, including:

● Refinery and petrochemical plants
● Food, medical, and pharmaceutical facilities
● Heavy industry and shipbuilding
● General process industries
● Hydraulic and pneumatic systems

Additionally, the EDN.716 has been submitted for Explosion-proof certification (Ex d IIC T6) to KOSHA (Korea Occupational Safety and Health Agency), with the certification expected to be granted following testing and inspection by mid-August 2025.
