[EDN.715: 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.715 series pressure transmitter features a durable stainless steel housing and a bright, clear LCD display with white backlight. This model is designed to be integrated with MDB series chemical (diaphragm) seals, making it suitable for highly corrosive and toxic gas environments.

Its corrosion-resistant construction allows it to be reliably used in challenging environments involving acids and aggressive or toxic gases, making it ideal for applications in the food and beverage, medical, pharmaceutical, and biotechnology sectors.

The MDB series chemical seals include a built-in diaphragm housed between process flanges. The wetted diaphragm materials can be customized upon request using specialized coatings or exotic materials such as Teflon (PTFE), Hastelloy C, Titanium, or Tantalum, depending on the application.

The sensing and electronic components of the EDN.715 series are designed and tested to meet the highest industrial standards. The signal processing unit integrates advanced protection technologies including noise filtering, burst resistance, insulation, and surge protection. Developed by DAHO’s in-house R&D center, each unit undergoes a rigorous quality control and full inspection process, ensuring reliable analog and digital signal output performance.

Key functional features include:

• RS485 digital communication
• Two relay/switch output channels for enhanced process control

During the development phase, the EDN.715 was subjected to over ten performance benchmarking tests against both domestic and international products to meet demanding industrial standards. Additionally, it achieved top-tier performance in EMC and EMI testing, validating its reliability under severe industrial conditions such as:

• High temperature exposure
• Electrical noise interference
• Burst and surge events

The EDN.715 is a truly versatile industrial pressure transmitter, built to ensure measurement stability in harsh field environments. It is suitable for a wide range of industries and applications, including:

● Refinery and petrochemical plants
● Food, medical, and pharmaceutical production
● Heavy industries and shipbuilding
● General process industry applications

Furthermore, Explosion-proof certification (Ex d IIC T6) has been submitted to KOSHA (Korea Occupational Safety and Health Agency), and official certification is expected following inspection and testing in mid-August 2025.
