Description
The Digital Temperature Indicator is a panel-mounted industrial instrument designed to accurately measure, display, and monitor temperature from thermocouple and RTD sensors. Unlike a temperature controller, which automatically regulates a heating or cooling process, this instrument focuses on high-accuracy temperature indication while providing a configurable relay or SSR output for alarms or simple switching functions. It is an ideal solution for applications where operators require reliable temperature monitoring without full PID process control.
The AI-5941 Digital Temperature Indicator supports thermocouple inputs (J, K, R, S) and Pt100 RTD sensors, making it suitable for a wide variety of industrial temperature measurement applications. The standard 96 × 96 mm DIN panel-mount design fits most industrial control panels, while the 0.3% full-scale accuracy and 250 ms sampling rate provide stable, responsive, and dependable measurement performance. A configurable relay output or SSR drive output allows the instrument to activate alarms, warning devices, or simple switching functions when preset temperature limits are reached.

FAQs
1. What is a Digital Temperature Indicator?
A Digital Temperature Indicator is an industrial temperature monitoring instrument that measures and displays temperature from connected RTD sensors or thermocouples. It is designed primarily for temperature indication and monitoring rather than automatic process control.
2. What is the difference between a Temperature Indicator and a Temperature Controller?
A Temperature Indicator displays the measured process temperature and may provide alarm or switching outputs, whereas a Temperature Controller actively regulates the process temperature using control methods such as PID or ON-OFF control to maintain a desired temperature setpoint.
3. Which sensors are supported?
The AI-5941 Digital Temperature Indicator supports thermocouple inputs (J, K, R, and S) as well as Pt100 RTD sensors, making it suitable for a wide range of industrial temperature measurement applications.
4. What output options are available?
The instrument is available with either a relay output or an SSR (Solid State Relay) drive output, allowing users to select the most suitable option for alarm indication, process monitoring, or switching applications.
