What is a Temperature Sensor?
A temperature sensor is a device that detects temperature and converts it into an electrical signal that can be displayed, recorded, or transmitted to controllers such as PLCs, DCS, SCADA, or indicators.
Industrial temperature sensors help maintain process consistency, protect equipment, optimize energy consumption, and improve production efficiency.

Frequently Asked Questions :-
Which temperature sensor is the most accurate?
RTDs are generally preferred for applications requiring high accuracy and long-term stability.
What is the difference between an RTD and a Thermocouple?
RTDs offer higher accuracy and stability, while thermocouples support much higher temperature ranges and faster response.
Where are thermocouples commonly used?
Thermocouples are widely used in furnaces, boilers, kilns, steel plants, and other high-temperature industrial processes.
Can temperature sensors be connected to PLC or SCADA systems?
Yes. Temperature transmitters convert sensor signals into standard outputs such as 4–20 mA or HART, making them compatible with PLC, DCS, and SCADA systems.
