Product Description

The Honeywell STR12D-21A-00000-1C-CM-B67M is a high-precision differential pressure transmitter from Honeywell's ST3000 Series 100, designed for critical applications requiring accurate and reliable measurement of pressure differentials. This model features a 0–100 inH₂O (0–249.08 mbar) calibrated range and is equipped with 316L stainless steel diaphragms, making it suitable for harsh environments and corrosive media. The transmitter utilizes Honeywell's Digitally Enhanced (DE) protocol, providing advanced diagnostics and integration capabilities with modern control systems. With a maximum allowable working pressure (MAWP) of 2500 psig (172 bar) and a wide operating temperature range, the STR12D-21A is ideal for applications such as level measurement in pressurized vessels and flow measurement for slurries and high-viscosity fluids.​
