VI. Frequently Asked Questions

Is the product's anti-corrosion coating easy to damage? What precautions should be taken during installation and transportation?

Answer: The PTFE anti-corrosion coating has high mechanical strength, but it is still necessary to avoid scratches by sharp objects or strong impacts; during installation and transportation, protective measures should be taken to prevent damage to the anti-corrosion coating, otherwise the anti-corrosion function will fail or the service life will be shortened.

Can the product be used temporarily in environments exceeding 220℃?

Answer: It is not recommended. The designed long-term operating temperature of the product is ≤220℃. Exceeding this temperature will cause attenuation of the PTFE anti-corrosion coating performance, affect the stability of the PT100 thermal resistance element, and even cause permanent damage. It must be used strictly within the rated temperature range.

How to choose between threaded and flange connection methods?

Answer: ① Threaded connection: Suitable for scenarios with small pipeline diameter and low pressure, featuring convenient installation and flexible disassembly; ② Flange connection: Suitable for scenarios with large pipeline diameter, high pressure or strong vibration, featuring firmer installation and better sealing performance, which can avoid leakage of corrosive media.

What is the recommended calibration cycle for the product?

Answer: For regular corrosive scenarios, annual calibration is recommended; for harsh scenarios with strong corrosion, high temperature (close to 220℃) or frequent vibration, the cycle should be shortened to 6 months to ensure the measurement accuracy meets process requirements; calibration must be performed with a standard constant temperature tank and high-precision instruments.

What are the possible reasons for abnormal measurement data of the product?

Answer: ① Damage to the anti-corrosion coating: Leading to corrosion of the probe and affecting element performance, it is necessary to check whether the anti-corrosion coating is intact; ② Loose or reversed wiring: Incorrect 3-wire system wiring will affect accuracy, and the wiring needs to be rechecked; ③ Failure of supporting equipment: The display or control equipment can be replaced to check whether it is an external equipment problem; ④ Element aging: The performance of the element degrades after long-term use, and it is necessary to contact the manufacturer for inspection, repair or replacement.
