Introduction to Sensor
Fine-Wire Thermistor (ST-200)
Designed for Small Surface Temperature Measurements
The ST-200 Surface Temperature Sensor is a high-accuracy fine-wire thermistor designed for measuring delicate surfaces and small samples. Its ultra-fast response time delivers precise temperature readings in less than one second.
Specifications
Specifications
| Specification | Value |
|---|---|
| Measurement Range | -50 to 70 °C |

| Self-Heating | Less than 0.01 °C (typical, assuming pulsed excitation of 2.5 V DC); 0.08 °C at 5 °C (maximum, assuming continuous input excitation of 2.5 V DC) |
| Operating Environment | -50 to 70 °C; 0 to 100% relative humidity |
| Resistance | 10,000 Ω at 25 °C |
| Input Voltage Requirement | 2.5 V DC excitation |
| Output Voltage Range | 0 to 2.5 V DC (assuming input excitation of 2.5 V DC) |
| Current Drain | 0.1 mA DC at 70 °C (maximum, assuming continuous input excitation of 2.5 V DC) |
