Pressure Transmitter EDN.620

Flush Diaphragm & All Stainless Steel Housing

The EDN.620 pressure transmitter is designed for applications involving viscous media or basic hygienic environments. Featuring a flush diaphragm structure, all wetted parts are made of stainless steel to ensure durability and hygiene. The standard process connection is G1/2", and the sealing O-rings can be customized to FKM, EPDM, or metal based on user requirements.

Both the housing and the wetted components are constructed entirely from stainless steel, providing excellent resistance to corrosion and chemical exposure.

This product is suitable for a wide range of industrial and hazardous environments, including oil and chemical plants, semiconductor processing lines, nuclear power facilities, oxygen supplying stations, and gas compressors. It is also widely applicable in the food and beverage, pharmaceutical, and medical industries.

The EDN.620 integrates a high-precision piezoresistive silicon pressure sensor, utilizing advanced microelectronics and PCB design technology. The signal amplification circuitry is built to withstand challenging industrial conditions and has passed rigorous tests for noise immunity, burst protection, insulation, and surge resistance.

Each unit undergoes full-scale individual calibration and quality inspection to ensure precise analog signal output and long-term stability.

Accuracy options are available depending on the application:
Standard accuracy is ±0.35% F.S, with optional high-precision versions of ±0.25%, ±0.1%, or ±0.05% F.S.

The EDN.620 is suitable for all types of process control and industrial measurement environments, particularly where high accuracy and reliability are critical.
