Description
The PRHD is a high-static differential pressure gauge featuring a dual-diaphragm design that withstands static pressures up to 30 MPa, enabling safe and accurate differential measurement even in high-pressure lines. Constructed entirely from stainless steel (304 SS or 316 SS), with matching wetted parts, it offers excellent corrosion resistance for demanding industrial environments. The instrument supports measuring ranges from 0–10 kPa to 0–600 kPa and is suitable for both liquid and gaseous aggressive media. Closely matching the specifications of the WIKA 732.14, the PRHD includes an adjustable zero mechanism, safety-glass window, and IP56 protection (optional IP67). It is ideal for chemical processes, pump monitoring, filter condition detection, and level differential measurement where robustness and safety are essential.
