Process operations and sites have several points of temperature that have to be monitored. Many of these measurements utilize thermocouples. When thermocouples fail or burnout they normally go open circuit due to any number of processes or environmental issues.
In an effort to catch these thermocouples before they fail, look to the TDZ3/THZ3 Smart HART Dual Input Temperature transmitters that have corrosion detection capability for thermocouples to warn you when the resistance in the thermocouple circuit is stating to increase, that is usually an early indication of a pending element failure. The THZ3/TDZ3 transmitter family can be HART or DTM programmed and carries worldwide approvals.
