Temperature Instruments

Industrial thermometers can be selected based on measuring principle and application requirements. Common types include bimetal thermometers, gas-actuated thermometers, thermocouples, RTDs (Resistance Temperature Detectors), and temperature transmitters. Bimetal thermometers feature a simple and durable design, making them suitable for general industrial use and medium-temperature measurement, while gas-actuated thermometers are ideal for remote indication and temperature monitoring of large equipment. For high-temperature processes such as industrial furnaces and combustion systems, thermocouples are commonly used. RTDs provide excellent accuracy and stability, making them suitable for medium- to low-temperature process control and precision measurement. Temperature transmitters convert temperature signals into standard outputs such as 4–20 mA for remote transmission and system integration.
