Frequently Asked Questions

Model Selection & Compatibility

Q: Which models meet hygiene standards for the food and beverage industry?

A: Prioritize SM series (magnetic-inductive), SI6000, and SA8000. All are certified by 3A and EHEDG, with IP69K protection, suitable for CIP/SIP sterile cleaning, and 316L material meets food-grade requirements.

Q: What should be noted when measuring highly corrosive media?

A: Choose corrosion-resistant versions (SM8000, SA8000, SU series). Ensure wetted parts are 316L stainless steel + corrosion-resistant liner, and seals are FKM material to avoid sensor damage from medium corrosion.

Q: Are there universal models for measuring both liquids and gases?

A: Yes, SI and SA series thermal sensors are universal. Avoid sudden temperature changes of the medium, and check the measuring range during model selection.

Installation & Usage

Q: Will insufficient straight pipe sections affect measurement accuracy?

A: It will affect most models; only SB/SBG/SBY series do not require straight pipe sections. For other models, it is recommended to reserve front and rear straight pipe sections to reduce errors caused by fluid disturbance.

Q: How to avoid sensor failures in industrial sites with strong vibration?

A: Prioritize models with anti-vibration design (SA, SI series). Reinforce interfaces during installation to avoid probe collision, and keep away from high-power equipment to reduce electromagnetic interference.

Troubleshooting

Q: What are the common reasons for no signal output from the sensor?

A: Most likely due to incorrect wiring (reverse polarity), power failure, or probe blockage/scaling. First check the wiring, then clean the probe and verify if the power supply voltage meets the requirements.

Q: How to handle large deviations in measurement results?

A: First verify medium compatibility, then check if the installation is standard and if the probe is worn. Finally, calibrate the sensor parameters and restart the device for testing.

After-Sales & Maintenance

Q: What is the after-sales warranty period?

A: The global unified warranty period is usually 1 year, and some models can be extended to 2 years (confirm purchase terms in advance).

Q: Do sensors need regular calibration? What is the cycle?

A: Regular calibration is required. It is recommended once a year for industrial scenarios, and once every 6 months for hygienic and high-precision scenarios (e.g., pharmaceuticals).
