Grounded Junctions -The thermo-elements are welded into the end cap using the same weld rod as the sheath material. Fast time response. Recommended for high-pressure applications.
Ungrounded Junctions - The thermo-elements are welded together and are electrically isolated from the sheath. Recommended for applications where stray EMF’s would affect the reading.
Exposed Junctions -The thermo-elements are welded together outside of the sheath. This provides the fastest time response but exposes the elements to contamination. Electrically isolated from the sheath.
Approximate response time in seconds.
Values are for 2/3 of total temperature change from 0 to 100% as measured in water.
