Mounting a Diaphragm Seal

When mounting a diaphragm seal, it is essential to pick the right option for your application. Diaphragm seals play an important role in protecting pressure instrument sensors from dangerous process media. Making sure they are mounted correctly is essential to ensuring they fulfill that role. Before ordering, you should make certain that the mounting method you choose is the right one.

There are several methods for mounting a diaphragm seal. First, they can be mounted using a capillary. This usage is restricted by the system fill fluid limit. Secondly, they can be directly mounted. This method is recommended only for temperatures up to 150 degrees Celsius, or 302 degrees Fahrenheit. Finally, you can mount diaphragm seals with cooling adapters, up to the system fill fluid limit. This method allows for temperature reduction. In each of these cases, the process connection, seal type, and material may differ.

Direct Mounting

Direct-mounted diaphragm seals may be attached to mechanical pressure gauges, switches, and transmitters. In this case, a flanged, threaded, or sanitary process connection may be used. It is important to understand the type of process connection you need before ordering. A direct mount may be ideal in certain circumstances; in other instances, use of a capillary or cooling adapter may be ideal. Ensure your mounting method matches the process connection, diaphragm seal type, and application requirements.

Capillary Mounting

Several types of diaphragm seals feature process connections that are perfect for capillary mounting. Capillaries offer the advantage of remote mounting; the reasons you may need this type of setup are entirely specific to your facility’s layout and the demands of your application. When using the capillary method, it is very important that you choose a capillary armor to protect the line. There are many protection types available, and ESP will gladly provide you with additional assistance with option selection.

Cooling Adapter Mounting

Cooling adapters are used to keep pressure instruments from being negatively affected by high temperatures. Placed between the diaphragm seal and the measuring instrument, these adapters deliver significant temperature reduction. Various types are available, with a range of connection types and maximum temperatures.
