Get Warnings on Sensor Resistance Level Increases With the THZ3 and TDZ3

Get Warnings on Sensor Resistance Level Increases With the THZ3 and TDZ3
Under normal conditions, the loop resistance of a thermocouple will gradually change with temperature. However, exposure to extreme high temperatures can cause the resistance to increase at a substantial rate. This can be a sign of several issues within your sensor. For example, high temperatures can release impurities and chemicals within the thermocouple wire insulation that diffuses into the thermocouple metal and changes its characteristics. This can possibly lead to resistance increases as the thermocouple insulation material is breaking down.

Know Your Corrosion Protection Is Working With the CPMS

Know Your Corrosion Protection Is Working With the CPMS
In May, California's largest oil spill in 25 years occurred when at least 101,000 gallons of crude oil spilled out of a pipeline near Santa Barbara. While the cause of the rupture is still unknown, federal investigators found that almost 80 percent of the pipeline had been worn down due to corrosion near the point where the break happened. This accident highlighted the need to take steps to mitigate the impact of corrosion on pipelines and other sites.

E-HELP: No Cabling Restrictions for FM Approvals on SIX

E-HELP: No Cabling Restrictions for FM Approvals on SIX
Q: I want to use an SIX Signal Isolator/Converter in a loop with a cable run of 1200’. Are there cable parameter values (i.e. maximum inductance/capacitance) that must be met in order to maintain the FM Non-Incendive certification?
