Thermistors, Thermocouples, and RTDs: Which Sensor is Best for You?When it comes to temperature measurement, selecting the right sensor is critical for obtaining accurate, reliable data. As a data logger manufacturer, we understand that choosing the appropriate sensor for your application can directly impact the success of your temperature monitoring. Here, we’ll explore the key differences between thermistors, thermocouples, and resistance temperature detectors (RTDs), helping you choose the right data logger for your needs.Thermistors What is a Thermistor? A thermistor is a temperature-sensitive resistor that exhibits a significant change in resistance with temperature changes. Typically made from ceramic or polymer materials, thermistors are highly sensitive and accurate within a limited temperature range.Advantages:• High Sensitivity: Thermistors provide precise readings within their operational range.• Cost-Effective: They are affordable and easy to integrate into various systems.• Compact Size: Their small form factor allows for use in tight spaces. Limitations:• Limited Temperature Range: Generally, thermistors are effective within -50°C to 150°C.• Non-linear Response: The r...

Thermistor and Water

An NTC thermistor is designed to measure temperature changes in different applications, but it is truly ideal for working in liquids (such as water). This is a result of long-term reliability and stability. They are the most accurate temperature gauges (when compared to a thermocouple), which allows for extremely close readings.A thermistor placed in water will most likely stay in one place for extended periods of time. A thermistor offers long-term durability for thermistor in water-based applications. A thermocouple will begin to weaken, which degrades its ability to read temperature accurately. Having to consistently replace thermocouples will intermittently stop production.A study about water temperature changes in Lake Tahoe has just recently ended. It was a 40-year study that suggests global warming is responsible for an increase in temperature in the lake (there has been a consistent rise over the last four decades). This is a big problem for the current habitat of the lake, and the warmer water threatens to destroy the whole eco-system.NTC thermistors were extensively used for this study because of their high accuracy rates. The thermistors helped to prove that the temperat...
