EDN.815 — Industrial Pressure Transmitter with Aluminium Housing and White Backlight LCD

·         Housing made of aluminium

·         LCD window with white backlight and bar graph display

·         Wetted parts made of stainless steel

·         Accuracy: better than ≤ 0.5% F.S

·         Explosion-proof rating: Ex d IIC T6

The EDN.815 series pressure transmitter features a durable aluminium housing and a bright white LCD display with backlight, providing excellent visibility even in dim industrial environments.
It is designed to be compatible with DAHO’s MDB series chemical (diaphragm) seals, making it suitable for use under harsh conditions such as exposure to acids or aggressive and toxic gases.
The housing surface is powder-coated for superior corrosion resistance, making the EDN.815 series ideal for general industrial applications.

The MDB diaphragm seal model can be manufactured with various special materials for the wetted parts, according to user specifications:

·         Teflon-coated

·         Hastelloy C22 or C276

·         Titanium

·         Tantalum

·         Monel

·         Gold-plated

 

Advanced Design and Electronics

The EDN.815 incorporates a high-precision pressure sensor and advanced electronic amplifier circuitry, designed and tested under strict quality control standards.
It includes comprehensive Noise, Burst, Insulation, and Surge protection technologies, ensuring long-term stability and reliability.
All transmitters undergo 100% inspection and functional testing at DAHO’s technology research center to guarantee accurate analog and digital output signals.

 

Optional Features

The EDN.815 series offers optional RS485 digital communication and dual relay/switch outputs, allowing users to configure the system according to their specific application needs:

·         RS485 communication

·         2-channel relays [2 switches]

 

Applications

Thanks to its rugged design and versatile compatibility, the EDN.815 series can be applied across a wide range of industrial environments:

·         Oil refining and petrochemical plants

·         Food, medical, and pharmaceutical industries

·         Heavy industry and shipbuilding

·         General process industries

 

Performance Validation

During development, the EDN.815 underwent more than ten rigorous comparative performance tests against domestic and international models.
It also passed EMC and EMI compliance testing, proving its superior resistance to environmental influences such as temperature fluctuations, noise, and surge conditions commonly found in industrial sites.
This ensures safe and stable measurement performance even in demanding and aggressive environments.

 

Certification

The EDN.815 series has been submitted to the Korea Occupational Safety and Health Agency (KOSHA) for Explosion-proof certification (Ex d IIC T6), with certification expected by November 2025.
