Temperature Sensing Technology｜Spindle Thermal Monitoring Solutions

In high-speed grinding and precision machining, monitoring spindle temperature is essential for stable performance and dimensional accuracy. We adopt multiple types of high-precision temperature sensors to monitor and control internal temperature changes in real time. Below are the common sensor types used in spindle applications:

 

1. KTY84 | High-Sensitivity Silicon Temperature Sensor

• Application: Motor windings, bearing housings, cooling system monitoring
• Temperature range: -40°C ~ 300°C
• Accuracy: ±1°C
• Features: High linearity response to temperature changes; ideal for thermal management in high-speed rotating equipment
• Detection Reference: ~603Ω at 25°C

 

2. PTC130 | Overheat Protection Temperature Sensor

• Application: Spindle bearings, motor coils, thermal protection circuits
• Operating temperature: Approx. 130°C (customizable)
• Accuracy: ±3°C
• Features: Sharp resistance increase when temperature exceeds threshold, triggering overheat protection

 

3. PT100 | Platinum Resistance Temperature Sensor

• Application: Cooling systems, environment monitoring, precision thermal control
• Temperature range: -200°C ~ 600°C
• Accuracy: ±0.1°C (Class A), ±0.3°C (Class B)
• Features: Excellent long-term stability, ideal for high-precision applications
• Detection Reference: ~109.7Ω at 25°C

 

4. PT1000 | High Accuracy & Long Distance Sensor

• Application: Precision machining spindles, smart temperature control, remote monitoring
• Temperature range: -200°C ~ 600°C
• Accuracy: ±0.1°C (Class A), ±0.3°C (Class B)
• Features: Higher resistance than PT100, better for long-distance signal transmission and noise resistance
• Detection Reference: ~1097Ω at 25°C
