That includes protection from excessive pulsation and/or vibration found in challenging conditions. While there are many types of pressure gauges to choose from, the challenge is finding the one that works best for your specific situation.  Liquid-filled pressure gauges, direct drive pressure gauges and dampened movement options like Ashcroft’s ***PLUS!™*** Performance all have pros and cons to consider. As a leading authority in pressure gauges, Ashcroft helps customers like you understand the advantages and drawbacks of different products so you can make a more informed purchasing decision.  Read this article to learn about the types of pressure gauges available for applications with high vibration, pulsation and other demanding conditions. When you are done you will be able to decide which one is best for your application. You will also find additional resources that can answer other common pressure gauge questions.  ## What is a Liquid-Filled Pressure Gauge? A [liquid-filled pressure gauge](https://www.ashcroft.com/products/pressure/pressure-gauges?pageNumber=1&postTypes=product&postsPerPage=12&sortType=menu_order&sortOrder=ASC&tax-pa_liquid-filled=1432) is a pressure measurement instrument that’s filled with a liquid like silicone or glycerin. This liquid serves as a cushion to stabilize the gauge needle, making it easier to read in conditions where pulsation and vibration are present. The liquid also reduces the impact of sudden pressure spikes that can lead to inaccurate readings or damage to the gauge itself. ### Liquid-Filled Pressure Gauge Pros and Cons![Liquid-fill pros and cons-1](https://blog.ashcroft.com/hs-fs/hubfs/Liquid-fill%20pros%20and%20cons-1.png?width=789&height=356&name=Liquid-fill%20pros%20and%20cons-1.png) ### What is a Pressure Gauge with Dampened Movement Technology? These dry-case pressure gauges use technology to dampen pulsation and vibration and improve gauge readability without the inconveniences of a liquid-filled gauge. For example, numerous Ashcroft Pressure Gauges are available with *PLUS!™* Performance technology. This proprietary Engineered Dampening Media (EDM) is injected into a canister that surrounds the gauge pinion shaft, movement plate, and backplate. A thixotropic liquid is used to adhere to the pinion to help reduce flutter, stabilize the pointer and enhance readability. As gauge pressure increases or decreases, movement of the gauge pinion creates a shear load, which causes EDM molecules to scatter. The EDM material gets thinner at the layer being sheared. With applications involving vibration, this allows for the dampening of the gauge pointer resulting in a steady, flutter-free pointer. *Figure 1. How Dampened Movement Technology Works. * ![plus\_exp](https://blog.ashcroft.com/hs-fs/hubfs/plus_exp.jpg?width=482&height=271&name=plus_exp.jpg) ### Ashcroft® *PLUS!™* Performance Pros and Cons This option has some advantages over standard dry or liquid-filled gauges:![Plus pros and cons](https://blog.ashcroft.com/hs-fs/hubfs/Plus%20pros%20and%20cons.png?width=704&height=507&name=Plus%20pros%20and%20cons.png) You can learn more about ***PLUS!™*** Performance [in our brochure](https://www.ashcroft.com/learn/product-documentation/?pageNumber=1&search=PLUS&sortType=menu_order&sortOrder=DESC&content_type=32). ## Ready to learn more? Now that you understand the differences between liquid-filled pressure gauges, direct drive pressure gauges and gauges with dampened movement technology Ashcroft’s ***PLUS!™*** Performance, you are in a better position to select the solution that’s right for your application.  If you want to learn more about [pressure gauges](https://www.ashcroft.com/products/pressure/pressure-gauges), here are a few related articles to check out: - [Ashcroft Gauge with PLUS!™ Performance - video ](https://youtu.be/4XamrEv17AU) - [Solid Front vs. Open Front Pressure Gauges](https://blog.ashcroft.com/solid-front-open-front-gauges) - [How To Identify Your Pressure Gauge and Get the Proper Replacement](https://blog.ashcroft.com/identify-your-pressure-gauge) - [How Do I Select the Right Pressure Gauge Range?](https://blog.ashcroft.com/select-pressure-gauge-range) - [How Often Should I Check the Calibration of My Pressure Gauge?](https://blog.ashcroft.com/pressure-gauge-calibration-interval) - [How Does Temperature Affect Pressure Gauge Performance?](https://blog.ashcroft.com/temperature-effects-pressure-gauges) - [How Much Do Mechanical Pressure Gauges Cost?](https://blog.ashcroft.com/blog/cost-pressure-gauges) Feel free to contact us today to [talk to one of our industry experts](https://sales.ashcroft.com/contact-us-question) and get your questions answered.
