Honeywell's STD820-A1HC4AS-1-A-AH0-11S-B-10A0-0 0-0000 differential pressure transmitter is built for accuracy and resilience. The unit weighs 8.3 lbs and operates under extreme conditions with a high upper range limit of 400 in H2O (or 1000 mbar) and a low limit of -400 in H2O (-1000 mbar). Thanks to its piezoresistive sensor technology, it can effectively respond to subtle pressure changes.

A distinctive feature of this transmitter is its impressive max turndown ratio of 400:1, which enhances measurement versatility across different applications. The construction utilizes plated carbon steel for the process head and 316L stainless steel for the diaphragm, thereby ensuring superior performance in harsh environments. To secure assembly, carbon steel is used for the bolt and nut components of the device.

The internal workings are filled with silicone oil 200, a choice that aids in effective pressure transmission. This model features a dual-ended head configuration which allows for installation flexibility, while the standard vent type simplifies venting requirements. Gaskets are composed of Teflon or PTFE, which contribute to the unit's leak-proof performance and integrity. Overall, the STD820-A1HC4AS-1-A-AH0-11S-B-10A0-0 0-0000 is a robust solution for precise differential pressure measurement.
