Dwyer Mercoid DA-21-153-16S Bourdon Tube Pressure Switch is a mechanical sensing device that uses a Bourdon tube to actuate electrical contacts as system pressure changes. It provides a pressure range of 800 to 8000 psi, making it suitable for high‑pressure industrial monitoring. The DA‑21‑153‑16S model belongs to the Mercoid line and is designed for automatic switching of equipment based on sensed pressure, delivering a robust solution for pressure control in demanding environments.
