■ Product Overview

The EDN.320 series of pressure transmitters is a general-purpose industrial pressure transmitter designed around a piezoresistive silicon pressure sensor featuring a stainless steel flush diaphragm.

 

Manufactured using the latest electronic component technology and PCB chip design, it incorporates noise, burst, isolation, and surge protection technologies to reliably amplify signals received from the pressure sensor. Additionally, 100% calibration is performed in accordance with strict process control and quality management standards, ensuring high reliability and stable analog signal output performance.

 

The EDN.320 was developed to meet the control and measurement management requirements of various industrial environments and is a versatile industrial pressure transmitter suitable for a wide range of applications, from general processes to harsh industrial environments.

 

■ Principle of Pressure Measurement

The EDN.320 measures pressure based on a piezoresistive silicon pressure sensor.

 

Fluid pressure is transmitted internally through a stainless steel flush diaphragm, causing pressure deformation in the silicon sensor. The minute electrical signal generated at this time is detected by a Wheatstone bridge circuit inside the sensor, and the PCB electronic circuit amplifies and calibrates it to convert it into a stable analog signal.

 

The design minimizes the impact of external factors such as noise and surges, enabling stable measurement even in diverse industrial environments.

 

■ Materials of Wetted Parts

All parts in contact with the fluid are made of stainless steel, providing excellent corrosion resistance in typical industrial environments.

 

Depending on the application environment, additional configurations such as a diaphragm seal or chemical flange are available to accommodate various process conditions.

 

■ Accuracy Class

The standard accuracy of the EDN.320 series is as follows:

▶ Standard : ±0.5% F.S

▶ Option : ±0.25%, ±0.1%

The product is supplied after undergoing a precise calibration process and maintains stable measurement performance even under the temperature and environmental conditions found in various industrial settings.
