Thechemical industrymanufactures a wide range of chemical and material products for industries that require durable and reliable measurement and monitoring technology for their production.
You need accurate and reliable measurement instruments that can stand up to harsh chemical environments. Misapplication or failure of instrumentation can lead to severe consequences like equipment loss, employee injury and environmental damage, so it is essential to use instruments engineered to withstand the severe demands of chemical processing operations.
This article will discuss some factors to consider when selecting the best pressure and temperature instrumentation for your chemical application.
Considerations when Choosing Instrumentation for the Chemical Industry
Here are some factors to keep in mind when you are selecting pressure or temperature instruments for your chemical or petrochemical application:
1. Safety Requirements
There are many considerations regarding application safety that impact the type of instruments you should choose. Ashcroft’sAcid Leak Detection (ALD)Assembly has a special yellow coating that changes to red once it is exposed to acids with a pH of ≤ 3, providing visual indication of a leak of process media. We also offer solid-front gauges such as the Ashcroft®1279 Duragauge® Pressure Gauge, to prevent operator injury in the event of a rupture.

If you need to read your gauge in low-light conditions, use a retroreflective dial material like the AshcroftDuraVis™ Gauge Dial. Unlike a reflective material that disperses light in different directions, DuraVis™ material reflects light back to the light source, making readability easier.
2. Media Compatibility
The sensor material you choose must be compatible with your process media. If you are using the wrong materials, you may encounter instrument damage or failure. Ashcroft provides aMaterial SelectorandCorrosion Guideto help you ensure that you have the proper instrumentation for your application’s media.
3. Material Traceability
The materials you use depend on the specific application, especially in hygienic applications, but they should be traceable to ensure reliability. Material traceability certifies that the materials used in your application have records chronicling their creation. Ashcroft can provide documentation for some instruments showing exactly where the material is from.
4. Application Requirements
Your application has certain requirements for pressure range, temperature and other factors. Pressure reference (gauge/vacuum, absolute or differential) is the first step in determining which technologies can be used in a design. Your instruments must also be designed to handle extreme temperatures. Ashcroft offers equipment recommendations from a metallurgist on staff to ensure you have the right instrumentation.
5. Protection from Harsh Conditions
Pulsation, vibration, and pressure spikes can all damage your pressure instruments. Accessories such as pulsation dampeners, throttle screws, steel needle valves or diaphragm seals can help protect your equipment. A liquid fill can also help protect a pressure gauge in these situations. Extreme temperatures also require protection for your instruments. Accessories such as siphons and capillary lines can help protect your instruments.
