| NTC Thermistor Sensors | HVAC systems, industrial processes, lamps | - Copper Shell: Thermal Conductivity 385 W/m·K (▲ Faster heat transfer) - Resistance: 8kΩ @25°C (IEC 60751) - Accuracy: ±0.5°C (Base) ▲, ±0.2°C (Advanced) ▲▲ (vs Industry Standard ±1.0°C) | ▲ High accuracy, fast response (0.5s), cost-effective. ▲ Copper ensures durability in corrosive environments. | Limited to -20°C to 150°C (Advanced). Requires analog-to-digital conversion for digital systems. |
| Thermocouple Sensors | High-temperature furnaces, engines | - Material: Metal alloys (Type K: ±2.2°C up to 1260°C) - Range: -200°C to 1800°C | ▲ Extreme temperature tolerance. Durable in harsh environments. | Slower response (2-5s), needs cold junction compensation. Lower accuracy at lower temps. |
| RTD Sensors (Pt100) | Lab equipment, precision HVAC | - Material: Platinum (±0.1°C @0°C, IEC 60751) - Stability: ±0.15°C/year | ▲ Highest precision, linear response. Long-term stability. | Higher cost, slower response (5-10s). Requires 3/4-wire configurations for accuracy. |
| Infrared Sensors | Non-contact HVAC vents, food processing | - Accuracy: ±2°C (varies with emissivity) - Response Time: 500ms | ▲ Non-contact measurement. Ideal for moving objects. | Affected by surface emissivity, dust, or reflective surfaces. Lower accuracy in complex environments. |
| Analog Sensors (Base) | Simple systems (lamps, basic thermostats) | - Output: 0-5V (linear, 0.1°C resolution) - Cable: Silicone (abrasion-resistant, -40°C to 105°C) | ▲ Low cost, easy integration. Direct voltage output simplifies wiring. | Susceptible to electrical noise. Limited to -20°C to 120°C (Base). |
| Digital Sensors (Advanced) | Smart systems (IoT, industrial automation) | - Protocol: I2C/SPI (up to 400kHz) - Resolution: 0.01°C - Cable: Customizable length (up to 5m) | ▲ High resolution, noise immunity. Supports long-distance data transmission. | Higher cost. Requires digital interface (e.g., microcontroller). |
