The EDN.810 pressure transmitter is engineered for demanding industrial environments, featuring a rugged aluminum housing and a high-visibility LCD for clear, real-time readings.

This series adopts a piezoresistive silicon pressure sensor constructed from stainless steel, delivering both durability and precision.

Its classic external design allows for seamless integration across a wide range of industrial applications.

 

The media-contacting components are built with corrosion-resistant stainless steel, ensuring high accuracy and long-term stability in continuous use.

By incorporating the latest advancements in electronic components and PCB chip design, the EDN.810 stands out as a high-performance solution tailored to modern industry needs.

 

The signal processing unit responsible for amplifying and stabilizing signals from the sensor is designed to withstand extreme industrial noise, burst, surge, and insulation stress.

Every device undergoes strict 100% quality control under DAHO’s in-house system to guarantee reliable analog and communication output signals.

 

The EDN.810 series offers RS485 digital communication and two-channel relay outputs, enabling users to select and apply output options that best fit their systems.
