The gearbox temperature sensor uses a platinum thermistor housed in a probe tube, measuring temperature via a variable resistance signal. The system processes this signal for real-time monitoring to ensure operational safety.
RTD measures temperature via metal resistance change (e.g., PT100). Highly accurate (±0.1°C) and stable, it's used in industry and labs from -200°C to 600°C. More reliable but slower than thermocouples.
Product Feature
· Precision Temperature Measurement: Utilizes a platinum thermistor probe that detects temperature variations through resistance changes for accurate monitoring.
· Robust & Sealed Construction: Features an armored stainless steel tube and brass housing for mechanical durability and airtight protection.
· Reliable Protection & Connectivity: Braided rubber sheath resists mechanical stress while specialized connectors ensure stable signal transmission.
