Your low-pressure transducer is an important part of your HVAC, critical environment, clean room or pharmaceutical application. Strict requirements for safety and sanitation need accurate and reliable pressure measurements. In some installations, the pressure transducer is required to be located at a certain distance away from the pressure source. But what if the transducer is located far away from the pressure source? What effect can the length of pressure tubing have on your pressure readings?

Your pressure sensor is a vital component of your equipment or system. When properly specified your system will operate safely and to expected performance levels over the design life of the system or equipment, but only if you have the right sensor that’s appropriate for your application. The wrong pressure sensor can result in equipment damage, worker injury or out-of-specification measurements. So, how can you ensure you choose the right one?

Not every application is the same, so you need to get the right equipment for your specific needs. When it comes to temperature measurement, inaccurate readings can severely impact your process. So, how can you ensure you are correctly and reliably monitoring temperature?

Heating, ventilation and air conditioning (HVAC) systems are a critical part of a building’s operation. They ensure that an indoor environment is comfortable for occupants by controlling humidity, temperature and air quality. However, the cost of running these systems can be a concern for building owners as inefficiencies in an HVAC system could increase building management costs, especially if the pressure sensors used to monitor and control the system are not accurate.

No matter what industry you work in, diaphragm seals (also referred to as isolators) and welded assemblies are used to protect your pressure and temperature instrumentation from corrosive process media. After decades of making quality pressure and temperature gauges and sensors to help keep processes performing reliably and efficiently, Ashcroft has seen just about every scenario where something can go wrong. One reason we like to share our expertise is to help people like you who may be experiencing a similar issue that we can help solve. In this article, you will learn what a welded diaphragm seal assembly is and how it is used to help mitigate the damaging effects of high temperature, pulsation and vibration endured by your instruments. You will also see how these assemblies can ensure reliable and accurate pressure readings of your process. When you are done, you will find links to additional resources that can help you learn more about related topics.

How many times have you gone to the refrigerator for a glass of milk only to find it has spoiled? How about that classic car you want to drive, just to find the battery dead and tires flat? These are just two examples of how inadequate storage and lack of periodic inspections can significantly alter experiences. Your pressure gauge needs to be stored in a manner that ensures it’s in working order when you’re ready to use it. If not, it could end up damaged or out of calibration.
