Product type
Temperature sensors are devices used to measure temperature in various environments. They operate by converting thermal energy into an electrical signal that can be interpreted by monitoring systems. Common materials used in temperature sensors include thermocouples, thermistors, and semiconductor materials, each offering different levels of sensitivity and accuracy. These sensors are typically employed in industrial processes, HVAC systems, and consumer electronics to ensure optimal temperature control and monitoring.
| Measurement range | -200°C to 1000°C |
| Output type | Analog or digital |
| Response time | From milliseconds to several seconds |
| Accuracy | ±0.5°C to ±2.0°C |
| Power supply | 5V to 30V DC |
| Sensor type | Thermocouple, thermistor, RTD |
When selecting temperature sensors, buyers should consider the specific application requirements, including the measurement range and accuracy needed. It's important to specify the type of output required (analog or digital) and the environmental conditions the sensor will be exposed to. Additionally, buyers should check for any necessary certifications and tolerances based on industry standards. Quantities should be determined based on project needs and future scalability.
