RTD vs Thermocouple: Which Temperature Sensor Should You Choose?
The short answer Choose an RTD when you need high accuracy and stability at low and medium temperatures, especially below 400–600 °C. Choose a thermocouple when you need a higher…
2026-11-10Pt100 vs Pt1000: Differences, Accuracy and When to Use Each
What is the difference? Both Pt100 and Pt1000 are platinum RTDs. The number refers to the nominal resistance at 0 °C: Pt100: 100 Ω at 0 °C Pt1000: 1000 Ω at 0 °C They use the same…
2026-11-102-Wire vs 3-Wire vs 4-Wire Pt100: What Is the Difference?
Why wiring matters for Pt100 A Pt100 changes resistance by only about 0.385 Ω per °C. The cable and connection resistance can therefore be a significant part of the measured value…
2026-11-10K-Type Thermocouple for Kilns and Furnaces: Selection Guide
Why Type K is common in kilns and furnaces Type K is the most widely used generalpurpose thermocouple. It offers a wide temperature range, good linearity, low cost and broad avail…
2026-11-10HVAC Temperature Sensor Selection: Pt100, Thermistor or Thermocouple?
Start with the control system The best HVAC sensor depends on what it connects to. A building controller may expect a 10 kΩ NTC thermistor, a Pt100 or Pt1000 RTD, a 0–10 V signal,…
2026-11-10Sanitary Temperature Sensors for Food, Dairy and Pharmaceutical Production
What makes a sensor sanitary? A sanitary temperature sensor is designed to be cleanable and to avoid crevices where product or bacteria can accumulate. The key design points are t…
2026-11-10How to Choose a Pressure Transmitter for Water and Wastewater
Define the pressure range first Choose a range where normal operating pressure sits around the middle of the span. A transmitter that runs near the top of its range has less margi…
2026-11-10Temperature Sensor Calibration: Points, Certificates and Intervals
Why calibrate a temperature sensor? A calibration certificate tells you how much the sensor deviates from a reference at defined points. It does not make the sensor more accurate,…
