Ensuring the reliability and safety of pressure measurement instruments is important in any application, especially when you are dealing with challenging environmental conditions. Rating systems including the Ingress Protection (IP) and National Electrical Manufacturers Association (NEMA) were created to level the playing field for manufacturers by providing a standardized measure of an instrument's ability to withstand environmental challenges. Understanding these rating systems can help you select the right equipment for your operational needs, ensuring instrument durability and safety. With close to two centuries of experience as a global leader in pressure and temperature instrumentation, Ashcroft can help you understand why these ratings are important and what to look for when selecting pressure instruments for certain applications. When you're done reading, we will also share additional information that can help guide your selection process.

When selecting pressure sensors for specific applications, it's important to understand the instrument's Ingress Protection (IP) rating. IP Ratings, which are also referred to as International Protection Ratings, determine the sensor's ability to withstand environmental factors such as moisture, dust and debris. These elements are commonly encountered in off-road vehicles, construction equipment, agricultural systems and other applications, and can significantly impact the performance and longevity of your pressure instruments. As a product manager at Ashcroft, a leading manufacturer of pressure and temperature instruments, I am often asked about which IP ratings are needed for instruments used in OEM applications. The answer depends on many factors. Read this article to learn more about the components of an IP rating, the factors that influence rating requirements and the applications covered in each category. When you are done reading, you will also find additional resources that may help you select the best IP-rated pressure sensor for your application.
