Whether you use industrial storage tanks for harvesting rainwater, providing municipal drinking water, irrigating fields, emergency fire suppression, or other purposes, you know how important it is to maintain accurate tank level pressure. One reliable solution is a pressure switch. This instrument is known for its accuracy, repeatability and versatility in water level management applications in water treatment systems, bubblers, scrubbers, and more. But how do they work? Ashcroft has been manufacturing pressure switches for decades and understands the unique challenges of pressurized tank systems. In this article, you will see how a pressure switch works and learn how multiple tank levels can be monitored and controlled using one or more pressure switch connections. When you are done reading, you will also find additional resources to answer other switch-related questions you may have.

If you work in an industry that relies on pressure switches or temperature switches you know that these small devices play a big role in making sure your applications run smoothly and efficiently. But at what price? The short answer is between $50 - $1500. Not helpful, I know. But, if you Google how much these instruments cost, you will be hard-pressed to find an accurate answer. The reason is simple. There are so many factors that go into the price of a switch, it’s nearly impossible to provide any kind of estimate without knowing your specific requirements. As a product manager for industrial switches at Ashcroft – a recognized global leader in temperature and pressure instrumentation - I can help you get closer to a more precise answer. However, keep in mind, this topic covers a lot of ground. So, for the purposes of this article, we will focus on pressure and temperature switches used in industrial applications. When you’re done reading, you will be able to validate the price range you are currently paying. You will also know what to expect if you are searching for a new supplier. Finally, you will be more prepared to make a pressure switch or temperature switch purchasing decision, whether you work with Ashcroft or not.

Calibration | zero and span

Your pressure sensors are an important part of your application, ensuring accurate and reliable measurements and the safety of your process and its operators. To keep your processes working properly, recalibration of your sensors may be necessary over time. Sensors can degrade over time as components are exposed to wear, temperature and cycling. This can lead to a loss of stability and drift in the output signal of the sensor away from its published specification. Using sensors that cannot be recalibrated would require the replacement of the sensor once it drifted outside of its specifications and its output signal was no longer reliable. This could cause your critical application to shut down temporarily until the sensor can be replaced. A sensor that can be recalibrated will not only prolong the sensor’s life but will have your process back up and running in no time at all. This article will discuss zero and span adjustability and the benefits it can provide to your process.
