FAQ
Q: Can I connect this K-type sensor directly to a PLC?
A: Yes. The K-Type Patch Thermocouple Temperature Sensor outputs a standard K-type millivolt signal. If your PLC or temperature module has a thermocouple input channel (with built-in or external cold junction compensation), you can read temperature directly. For 4-20mA requirements, add a transmitter.
Q: How do I ensure good thermal contact during patch installation?
A: Use high thermal conductivity paste or a thermally conductive pad, then secure the sensor with high-temperature tape or a mechanical clamp. Make sure the surface is clean and flat. Intimate contact is key to achieving fast response and rated accuracy.
Q: Do you support OEM / private labeling? What is the MOQ?
A: Yes, we offer OEM manufacturing and custom branding. There is no MOQ. Contact our sales team for details.
Q: What protections can I get?
A: The product is covered by a 12-month warranty. We will repair or replace any defective units and offer continuous technical support throughout this period.
