Frequently Asked Questions

What is an RTD temperature sensor?

An RTD (Resistance Temperature Detector) is a sensor that measures temperature by correlating the resistance of the RTD element (usually platinum) with temperature. It offers high accuracy and stability over a wide range.

Can you customize RTD sensors for specific applications?

Yes, we offer OEM and ODM services. Our engineering team can customize sensor length, probe material, wiring, accuracy class, and output signals to meet your exact requirements.

What certifications do your products have?

Our products comply with international standards. Some items are UL, TUV, and SGS certified. Railway cables meet DIN5510 and BS 6853 standards.

What is the lead time for orders?

Typical lead time is 15-25 days depending on order size and customization. Sample orders can be shipped within 7-10 days.
