Introduction to Sensor
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 |
| Measurement Uncertainty | ±0.5 °C (-40 to 70 °C) |
| Measurement Repeatability | Less than 0.05 °C |
| Non-stability (Long-term Drift) | Less than 0.02 °C per year (when used in non-condensing environments where the annual average temperature is less than 30 °C; continuously high temperatures or continuously humid environments increase drift rate) |
| Time Constant (time for detector signal to reach 63% following a step change) | 2 s |
| 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) |
| Dimensions | 25 mm length, 1 mm diameter |
| Mass | 60 g |
| Cable | 5 m of shielded, twisted-pair wire with Santoprene rubber jacket (high water resistance, high UV stability, flexibility in cold conditions), pigtail lead wires |
