Flanged Diaphragm Seal MT-S100FD

Description

1. Introduction to Flanged Diaphragm Seal MT-S100FD

The Flanged Diaphragm Seal MT-S100FD is a high-performance isolation and pressure transmission component designed for industrial applications where the process medium is highly viscous, corrosive, contaminated, crystallizing, or contains suspended solids. In many process conditions, direct contact between the measuring instrument and the process fluid is not ideal. The diaphragm seal provides the necessary separation between the medium and the pressure sensor, while transmitting accurate pressure values through a sealed system filled with silicone fluid.

This diaphragm seal is widely used with pressure gauges, differential pressure gauges, pressure transmitters, and pressure switches to ensure long-term measurement accuracy in demanding industrial environments. With a large volume flushed design and laser-welded diaphragm, the MT-S100FD ensures durability, chemical compatibility, and stable performance even under high-pressure and high-vibration operating conditions.

4. How the Flanged Diaphragm Seal MT-S100FD Works

The diaphragm seal operates as a physical barrier that isolates the process medium from the sensing element of the pressure instrument. The diaphragm flexes in response to the process pressure. This deflection is transmitted through a silicone sealing fluid to the pressure sensor without allowing the measured substance to come in contact with the instrument.

This system ensures:

• Accurate pressure transmission

• Extended instrument lifespan

• Reduced contamination risks

• Lower maintenance and cleaning frequency

The flushed diaphragm ensures smooth flow interaction and prevents blockages caused by viscous or crystallizing media, which is a key advantage in industrial processes involving thick or reactive fluids.
