Dual Sensor Input – Backup / Failover

Many plants have process stages with several points of temperature that have to be monitored. Many of these measurements are critical and thus will utilize dual elements or fully redundant sensors.

When these critical measurement needs arise and you can’t afford to have your process shut down, look to the THZ3/TDZ3 Smart HART Dual Input Temperature transmitters that allow you to configure the transmitter for a failover or backup mode. When the primary sensor fails the TDZ3 automatically switches to the backup sensor and the failure is reported via HART diagnostics and display. The THZ3/TDZ3 transmitter family can be HART or DTM programmed and carries worldwide approvals.

Key Attributes:

  • Backup or Failover mode on primary sensor failure
  • HART or DTM programmable
  • Worldwide hazardous area approvals
