Baumer DG Heavy Duty Mini Diaphragm Seal

A. Product Overview

The Baumer DG heavy duty mini diaphragm seal is a compact and durable pressure instrument accessory used to isolate measuring instruments from difficult process media. It is suitable for use with pressure gauges, pressure switches and other pressure monitoring instruments where direct contact with the process fluid may damage the instrument or reduce its working life.

This diaphragm seal is designed for heavy duty industrial applications and supports multiple pressure ranges. The available ranges include S11 from -1 to 0 bar and 0 to 4 bar, S12 from 6 to 70 bar, S13 from 100 to 400 bar and S14 from 250 to 600 bar.

The wetted parts are made from AISI 316 SS and AISI 316L, making the seal suitable for many process fluids. For more demanding media, special materials such as Monel and Hastelloy C are also available. The operating temperature range is from -40 degree C to 200 degree C, or as per the selected fill fluid.

Available process connections include 1/4 inch NPT male, 1/2 inch BSP male and 1/2 inch NPT male, making it suitable for different industrial installation requirements.

B. Working Principle

The Baumer DG diaphragm seal works by separating the process medium from the pressure measuring instrument. The diaphragm comes in contact with the process fluid, while the pressure gauge or pressure switch remains isolated from the actual media.

When pressure is applied to the diaphragm, the diaphragm deflects. This pressure is transferred through the internal fill fluid to the connected pressure instrument. The pressure gauge, pressure switch or transmitter then measures the pressure without being directly exposed to the process fluid.

This working principle helps protect the instrument from corrosion, clogging, crystallization, high temperature and aggressive process conditions. It also improves instrument life and measurement reliability in difficult applications.

C. Why It Is Used

The Baumer DG heavy duty mini diaphragm seal is used to protect pressure instruments in applications where the process media is not suitable for direct contact with the instrument sensing element.

It is commonly used when the media is corrosive, viscous, sticky, crystallizing, sediment-forming, hot or high pressure. Without a diaphragm seal, such media can damage the internal parts of a pressure gauge or pressure switch, block the pressure port or affect measurement accuracy.

The DG diaphragm seal provides a protective barrier between the process and the instrument. This makes pressure measurement safer, cleaner and more reliable in harsh industrial conditions.

It is especially useful for high pressure applications up to 600 bar, where a compact but strong diaphragm seal is required.
