The THZ3 and TDZ3 are dual input smart HART temperature transmitters that offer high-accuracy temperature measurements using various sensor types, providing a dual sensor input for backup, average, and differential measurements. They feature advanced device intelligence for monitoring sensor drift and alarms, as well as compliance with HART 7 for easy integration into control systems. These transmitters are designed for both hazardous and non-hazardous environments, with options for configurable displays and programmable parameters for precise temperature measurement control.
