Temperature Sensor
Temperature Sensor
| Features： | Applications： |
| ◆ Direct welding or soldering ◆ Moisture proof seal ◆ Double filament structure ◆ Flexible package structure tip ◆ Comply with RoHS and REACH standards |
◆ Thermotherapy Catheter ◆ Disposable endoscop ◆ Cryotherapy Catheter ◆ Ultrasound Ablation Catheter ◆ Tumor Ablation Needle ◆ Pain Management Electrode |
Description
The micro thermocouple is a flexible, high-precision sensor designed for fast and accurate temperature measurement. Made from metal alloy, it features wire gauges of 36–46 AWG, with the thermocouple tip diameter as small as 0.20mm. If a smaller outer diameter is required, customized solutions are also available.
Thermocouple lengths can be tailored for integration into medical catheters, ensuring optimal performance in complex applications.
