How to Choose the Right Industrial Thermometer
Bimetal Thermometers:
Use a bimetallic strip to measure temperature. The strip coils or uncoils with temperature changes, moving the pointer. Ideal for medium-temperature applications in durable environments like manufacturing and petrochemicals.
Expansion Thermometers:
Measure temperature through gas expansion or contraction in a sealed bulb and capillary tube. Suitable for long-distance measurement or large equipment monitoring, such as in power or oil facilities.
Thermocouples:
Generate voltage from the temperature difference between two metal junctions, ideal for high-temperature environments like industrial furnaces and combustion systems.
RTDs (Resistance Temperature Detectors):
Measure temperature by detecting changes in electrical resistance, providing high accuracy. Best for low to medium temperature ranges in process control and lab environments.
Temperature Transmitters:
Convert temperature sensor signals to standard output (e.g., 4-20 mA), ideal for remote monitoring and industrial automation systems.
