Product Description

The Honeywell STD720-E1HS2AS-1-A-CHB-11C-A-21A6-FX,F1-0000 is a high-precision differential pressure transmitter from Honeywell's SmartLine® series, engineered for demanding industrial applications requiring accurate and reliable pressure measurement. This model features a 316L stainless steel diaphragm and 316 stainless steel process head, ensuring durability and resistance to corrosive environments. With a maximum span of 400 in H₂O (1000 mbar) and a minimum span of 4 in H₂O (10 mbar), it offers a 100:1 turndown ratio, allowing for versatile measurement ranges. The transmitter supports HART® communication protocol and provides analog 4–20 mA output, facilitating seamless integration into existing control systems. Designed for applications such as flow measurement, level gauging, and pressure control, it delivers 0.05% accuracy, 0.02% stability per year, and fast response times of 100 ms, ensuring precise and timely measurements.
