IRA

When inserted into the center one-third of your pipeline, the tip of the IRA-4SS regulates your sample under flowing conditions. In-pipeline pressure regulation and the low internal volume of the IRA-4SS reduce lag time and get your sample to the analyzer faster. With less time in the sample line, ambient conditions don’t have the opportunity to negatively affect your sample.

Thermal fins add surface area to the probe tip, allowing pipeline gas to transfer some of its thermal energy to the regulated sample. This additional heat mitigates the cooling caused by pressure drops (Joule-Thomson effect) and helps prevent the sample from condensing.

Analytical devices require samples to be injected at a controlled pressure considerably lower than pipeline pressure. Capable of precise settings at low output pressures, the IRA-4SS keeps your analysis going and protects your sensitive equipment from costly damage and downtime caused by high or fluctuating sample pressure.

AI Control™ and an adjustable insertion length give you the flexibility to use the same IRA-4SS in multiple locations. Add the Welker Spring Range Kit to your probe regulator purchase, and you’ll further increase its functionality. With a set of three springs to choose from, you can easily change the pressure control range of the IRA-4SS for a new application.
