A new high pressure test rig will allow Endress+Hauser to test complete instrument assemblies to customer specifications. The rig, installed at its headquarters in Greenwood, Ind., provides a 100 percent test indicating that a specific instrument can withstand the design process pressure, up to 15,000 psi.

Certifying an entire instrument assembly that will be installed in process equipment such as high pressure boilers, reactors or catalytic crackers is important for customers in the oil and gas, chemical, power and energy industries. Engineering firms, end users and insurance companies have detailed and specific internal codes and specifications for the instruments. 

Located in an underground concrete pit for safety reasons, the nearly $1 million rig can generate pressure up to 15,000 psi to test devices up to 16' (4 m) long and with up to a 2" diameter. It is specially designed to test the company’s instruments, including its high pressure thermowell assemblies, but the rig can also test other instruments.

Prior to installation in Greenwood, Endress+Hauser performed such tests at its production plant in Maulburg, Germany.
