6'' DIAL0-400 MBAR /4000MMWC 1/2 BSP BOTTOM COMPLETE SS Diaphragm

About 6'' DIAL0-400 MBAR /4000MMWC 1/2 BSP BOTTOM COMPLETE SS Diaphragm

Diaphragm pressure gauges are designed for low-pressure (mbar range) and high-overload applications, featuring a sensitive, flexible diaphragm to measure viscous, aggressive, or contaminated media. Typical specifications include a 63mm-150mm dial, 1% to 1.6% full-scale accuracy, and Stainless Steel (SS316/304) construction.

• Dial Sizes: Commonly 63 mm, 100 mm, 125 mm, or 150 mm.
• Case Material: Stainless Steel (304 or 316) or die-cast aluminum.
• Diaphragm Materials: Stainless Steel 316L, Hastelloy C-276, or PTFE protected for corrosive, viscous, or contaminated media.
• Process Connections: 1/4 or 1/2 NPT/BSP(M), or flanged connections.
• Temperature Range: Typically -40 C 40C to +60 C+60 C (standard) or up to 120 C120 C (process temp)

Robust Stainless Steel Construction

Constructed entirely of polished stainless steel, including the sensor, case, connection, and bourdon tube, this pressure gauge is made for demanding environments. Its machined and welded build ensures a long operational life, high corrosion resistance, and consistent accuracy even in industrial settings.


Reliable and Accurate Monitoring

With an accuracy of 1.6% of full-scale deflection, the analog display delivers precise readings for pressure ranges up to 400 mbar or 4000 mmWC. The anti-glare aluminum dial and clear acrylic window allow for easy visibility and quick monitoring, essential for process safety and efficiency.


Versatile Application and Easy Installation

Designed for measuring the pressure of air, gases, and non-crystallizing liquids, this gauge is suitable for filters, liquid level measurement, and general process control. The 1/2 BSP bottom connection, complete mounting hardware, and external zero adjustment simplify installation and ongoing calibration.
