■ EDN.335 Pressure Transmitter for Scrubber Systems

-       Designed for scrubber systems

-       Optimized for low pressure measurement

-       Enlarged sensing port for easy maintenance

-       Cost-effective solution

 

■ Product Overview

The EDN.335 series is a pressure transmitter specifically designed for scrubber systems used in semiconductor and industrial processes.

 

Scrubber applications require high accuracy even at very low pressure ranges, and the EDN.335 is engineered to provide stable and reliable measurement under these conditions.

 

One of its key features is the enlarged sensing port, which helps prevent clogging caused by particles, sludge, or contaminants during operation. This design significantly improves ease of cleaning and maintenance.

 

The product offers a cost-effective solution while maintaining stable performance, making it suitable for demanding scrubber environments.

 

■ Pressure Measurement Principle

The EDN.335 measures pressure using a piezoresistive silicon pressure sensor.

 

Low pressure applied to the diaphragm causes slight deformation, which is converted into an electrical signal.

 

This signal is amplified and compensated to provide a stable output, ensuring reliable measurement even in contaminated or unstable process conditions.
