Q Do you provide customized solutions?
Yes. We support customization including special ranges, high/low temperature, corrosion/explosion protection, integrated structures, wireless outputs (4G/NB-IoT), multi-signal outputs, and non-standard threads or flanges.
-
Q What is the process and lead time for factory repair?
Process: application → return → inspection → repair → testing → return.
Lead time: 3–7 working days for routine repairs; 7–15 working days if core components require replacement.
-
Q How to obtain remote technical support?
Provide model, serial number, fault description, and on-site photos. We offer remote guidance, online debugging, and video support for wiring, setup, and troubleshooting.
-
Q What are the support channels and response time?
Support via telephone, WeChat, email, and official website.
Response within 30 minutes during working hours. Solutions provided within 2 hours for most issues. On‑site service within 24–48 hours locally.

The standard warranty is 12 months (extendable to 18–24 months for selected products). Free repair or replacement is provided for non‑human‑induced quality defects. Damage due to misuse, lightning, unauthorised disassembly is not covered.
-
Q How to troubleshoot no output or large fluctuation?
Check power supply, wiring, probe blockage or damage, grounding and shielding, electromagnetic interference, and vibration. Recalibrate zero and span if necessary.
-
Q What are the standard power supply and load range?
Standard power supply: 24VDC (12–36VDC).
For 2‑wire 4–20mA transmitters, typical maximum load ≤500Ω. 4‑wire instruments have almost no load limitation.
