Temperature Instruments Q & A
Q: What's the typical lifespan of industrial temperature sensors?
A: Quality sensors last 3-5 years with proper calibration. RTDs often outlast thermocouples by 30%.
Q: How often should calibration be performed?
A: Annually for most applications, quarterly for critical processes like pharmaceutical manufacturing.
Q: Can I use food industry thermometers in chemical plants?
A: Only if specifically rated for chemical exposure - most aren't. Check IP ratings and material compatibility.
Q: What's better for high-temperature measurements: thermocouples or IR?
A: Thermocouples handle up to 2,300°C directly, while IR works best for non-contact measurements up to 3,000°C.
Q: Are wireless temperature sensors reliable?
A: Modern industrial-grade wireless sensors achieve 99.9% data transmission reliability with proper network setup.
