The STD820-A1HC4AS-1-A-AH0-11S-A-10A0-00-0000 is a differential pressure transmitter from Honeywell's SmartLine series. It leverages piezoresistive sensor technology to deliver precise measurement capabilities. This device is capable of handling significant pressure ranges, with an upper range limit set at 400 inches of water (equivalent to 1000 mbar) and a lower range limit at -400 inches of water (or -1000 mbar).

Weighing in at 8.3 pounds, the device balances robustness with performance. It features a diaphragm composed of 316L stainless steel, ensuring longevity and corrosion resistance. Plated carbon steel is utilized in the process head construction, adding to the overall durability of the transmitter.

For filling, silicone oil 200 is employed, which contributes to the operational stability of the device. The transmitter is assembled with bolt and nut materials made from carbon steel. A standard vent type provides reliable pressure management, while the dual-ended head enhances versatility in installation and usage. A gasket made from Teflon or PTFE provides enhanced sealing for various applications. The transmitter can be mounted using an angled bracket for flexibility in installation, ensuring applications can be set up to meet specific requirements.
