This thermowell is ideal for coal pulverizers, fluidized beds, and any place where contact instrumentation might be subjected to Small Particle Erosion (SPE). JMS found that in many SPE applications customers were using OEM supplied hard faced thermowells with a variety of coatings. These thermowells were expensive to replace and could not withstand the harsh erosive environment of pulverized coal. The wear to these OEM supplied thermowells resulted in loss of reliability, change in response time and significant energy costs.

In response to these concerns, JMS developed a pressure sealed dependable alternative and has had some thermowells in place for more thant 6 years without appreciable wear.
