FAQ
- What's the difference between an RTD sensor and a thermocouple?
RTD sensors offer higher accuracy and stability, making them ideal for precision applications, while thermocouples can withstand higher temperatures and are more cost-effective for rugged environments. - Can infrared sensors measure temperature accurately from a distance?
Yes, infrared sensors measure surface temperature without contact, though accuracy can be affected by distance, target size, and surface material—closer range and larger targets generally improve accuracy. - Which temperature sensor is best for harsh industrial environments?
Thermocouples are generally the most durable choice for harsh conditions due to their ability to withstand high temperatures and physical stress.
