Endress+Hauser installs high pressure test rig in US

Tests complete instrument assemblies at pressures up to 15,000 psi to meet customer requirements

Endress+Hauser invested nearly $1 million in a state-of-the-art pressure test rig at their U.S. headquarters in Greenwood, Indiana. The rig allows them to test complete instrument assemblies to customer specifications, and it provides a 100% test indicating a specific instrument can withstand the design process pressure, up to 15,000 psi.

Improving delivery and certification times

Previously, Endress+Hauser did not have local high pressure testing capability. For example, Endress+Hauser performed such tests at its production plant in Maulburg, Germany. With the new high pressure test rig located in the Greenwood, IN production center, instruments can be tested and certified quickly, for faster delivery to customers in the US and the Americas. And because the test facility is in the U.S., it makes it easier for customers to schedule and witness the test.

Understanding the importance of each industry

Being able to certify the entire instrument assembly—not just the process connection—is important for customers in the oil & gas, chemical, power, energy and other heavy industries. In many cases, engineering firms, end users and insurance companies have detailed and specific internal codes and specifications for instruments that will be installed in critical, high-pressure applications, such as high pressure boilers, reactors or catalytic crackers.

Meeting customers' specifications and requirements

The test rig, located in an underground concrete pit for safety, generates pressure up to 15,000 psi (1000 bar) to test devices up to 16 feet (4 meters) long and with up to a 2-inch diameter. Each test is automated to execute customer-specific test and ramp up times. The test rig is specially designed to, but not limited to, test Endress+Hauser’s Levelflex GWR and Micropilot free space radar level instruments, capacitance probes, Liquiphant tuning forks and high pressure thermowell assemblies.

Ensuring safety with certification and documentation

The test rig can produce relevant certification and documentation to ensure there is a level of safety built into the system and reduce risk of failure. This certification and documentation is also often required by engineering firms, end users or insurance companies
