Product Description
The 11AH-BS2 is a high-range pneumatic absolute pressure transmitter from the Foxboro 11A Series. Using a force-balance mechanism, it converts absolute pressures up to 200 psi into a standard pneumatic output signal (3–15 psi), making it ideal for all-pneumatic control loops where electronic sensors are unsuitable.
Constructed with 316 stainless steel, this transmitter offers exceptional corrosion resistance and long-term reliability in harsh industrial environments, including high-vibration and explosion-hazard areas. Its built-in vernier adjustment allows on-line calibration without disrupting the process.
