Understanding the Omega 44004 Thermistor Datasheet and Its Applications
The Omega 44004 Thermistor Datasheet is a comprehensive guide detailing the specifications and performance characteristics of a specific type of thermistor manufactured by Omega Engineering. Thermistors are essentially resistors whose resistance changes significantly with temperature. The "44004" in its name denotes a particular model, often characterized by its material composition, resistance value at a standard temperature (like 25°C), and its resistance-temperature curve. Understanding this datasheet allows users to accurately predict how the thermistor will behave across a range of temperatures, which is crucial for reliable and accurate temperature monitoring. These thermistors are widely employed in various sectors due to their sensitivity and cost-effectiveness. Some common applications include:- Industrial process control
- Medical devices for patient monitoring
- Automotive engine management systems
- Home appliances like ovens and refrigerators
- Scientific instrumentation for precise measurements
- Resistance at 25°C (R25)
- Beta (β) value or the Steinhart-Hart coefficients, which are used to calculate temperature from resistance.
- Tolerance limits for resistance and temperature.
- Maximum and minimum operating temperatures.
- Response time characteristics.
| Temperature (°C) | Resistance (Ohms) |
