[Applications]

The industrial pressure transmitter series EDN is developed using a stainless steel piezoresistive silicon pressure sensor, and all wetted parts are made of stainless steel.

In line with the rapid advancement of pressure sensor manufacturing technology, the product incorporates highly precise electronic components along with advanced PCB chip design and assembly techniques. During the electronic design process, where small mV signals from the pressure sensor are received and amplified, the product has undergone rigorous testing for Noise, Burst, Insulation, and Surge performance, exceeding CE requirements.

Throughout manufacturing, strict process control and quality management procedures are applied to ensure stable analog signal generation. Finally, each product is individually calibrated and subjected to 100% inspection before shipment.

During the development stage, Dahotronix conducted more than ten different and stringent comparative tests against existing overseas and domestic products. As a result, the EDN.309 provides superior quality performance with universal functionality, making it suitable for industrial fields that require strict control and precise instrumentation management across various operating environments.

In particular, it is widely applicable to general hydraulic and pneumatic industries, pump industries, compressor industries, automotive industries, heavy industries, shipbuilding industries, semiconductor industries, pharmaceutical industries, wastewater and water treatment industries, energy industries, and food & beverage industries.

To ensure broad usability, the product has been designed as a low-cost solution with minimized production costs. Pressure ranges are available from 0…4 bar up to 0…250 bar through optimized component combinations. It delivers reliable pressure measurement performance even under harsh field conditions and supports a wide range of process connections and electrical plugs required in industrial applications.
