Diaphragm Monitoring System Ensures Safety, Reliablity

A diaphragm monitoring system, which features double diaphragms, performs two essential tasks in industrial settings. First, it protects the measuring instrument from hazardous liquids and gases. Second,  if the primary diaphragm is breached you are alerted, and the secondary diaphragm continues to function allowing you to continue operations.

Production managers always have to balance the safety, accuracy, and durability of their machinery. If they ignore one of the three, the other two will suffer as well. The engineers at WIKA build instruments with these managers in mind, developing rugged, accurate technologies, and a host of special features for them, including our patented diaphragm monitoring system.

The Value of a Diaphragm Seal

In industrial settings, a diaphragm seal is a single flexible wall between sensitive instrument parts and the substances that can damage or destroy them. The diaphragm seal enables a premium, well-designed gauge to provide the accurate pressure and temperature readings your operation requires.

Most industrial processes use substances that can cause instruments to break or fail prematurely, including:

• Hot liquids and chemicals

• Corrosive gases

• Potentially dangerous acids

A diaphragm seal protects the internal mechanisms of gauges and instruments and prevents clogging. It also prevents fugitive emissions that create environmental hazards.

Over time, even limited exposure to corrosive substances can damage instrumentation and gauges. With a diaphragm seal in place, the delicate sensors inside a gauge need never come in contact with hot, viscous, contaminated, or corrosive media.

Diaphragm Monitoring System: The Double-Diaphragm Advantage

Unfortunately, corrosive substances can wear down the toughest diaphragm, risking spills, leaks, and inaccurate pressure readings. That's why WIKA developed the diaphragm monitoring system. It works like this: There's a hard vacuum between the two diaphragm seals monitored by a pressure indicator. If the vacuum is ever compromised, the monitor sounds an alarm alerting plant personnel to the problem. The alarm can be visual, electrical or acoustic, depending on the user’s preference.The secondary diaphragm goes into action, helping avoid downtime.

The Diaphragm Monitoring System is available in a variety of designs and instrument configurations.

Getting All the Details Right

As many plant managers have learned too late, the devil truly is in the details when it comes to having reliable instrumentation. A lot can happen when incompatible elements come together--and the results usually aren’t good. You’ll rest easier with the diaphragm monitoring system.
