VI. Frequently Asked Questions (FAQ)

How to select the wiring mode of 6-wire RTD?

Answer: Follow the principle of "convenience and reliability". Select according to working conditions: waterproof joints for dustproof and waterproof scenarios, flameproof joints for flammable and explosive environments, and embedded display terminal heads for on-site display needs. Assembled RTDs can be equipped with ceramic terminal blocks or connectors; compensation wires are required for long-distance measurement.

How to choose the accuracy class?

Answer: Select Class A for high-precision measurement scenarios (e.g., scientific research, precision manufacturing); choose Class B for conventional industrial production scenarios (e.g., ordinary pipeline and equipment monitoring) to balance precision and cost.

How to determine the protection tube material and outer diameter?

Answer: For corrosive working conditions, select 316L or corrosion-resistant alloy; for conventional working conditions, SUS304 is suitable. The outer diameter should be chosen based on installation space and pressure resistance requirements. Standard options include 6mm, 6.35mm, and 8mm; custom sizes are available for special needs.

Does the product support customization?

Answer: Yes! Customizable parameters include resistance type (Pt100, Pt1000, Cu50, etc.), accuracy class, installation method (flanged/threaded/no installation), protection tube material/size, insertion length, wiring components, and explosion-proof/waterproof functions. Specific requirements should be specified during inquiry.

Are the product certifications complete?

Answer: Yes! The product has obtained SIL 2 functional safety certification, CE (LVD/EMC) certification, explosion-proof certification (GYB23.1907X), intellectual property management system certification (GB/T29490-2013), environmental management system certification (ISO14001:2015), and occupational health and safety management system certification (ISO45001:2018), complying with multiple national and international standards.

What information is required for inquiry?

Answer: Please provide the following information: ① Full product series number (if available); ② Application field (petroleum/chemical/power, etc.); ③ Required temperature range; ④ Fixing or installation type (movable flanged type, threaded type, no fixing type); ⑤ Protection tube material and diameter (if needed, e.g., 1Cr18Ni9Ti, 16mm, etc.); ⑥ Insertion length; ⑦ Accuracy class (Class A/Class B); ⑧ Other special requirements (e.g., explosion proof, custom lead length, etc.).

How to choose connection ways: The choice of termination should be convenient and reliable minded. There are ceramic wiring blocks, connectors, protective caps with compensation wires, protective caps with metal sleeves, and compensation wires to choose for wire connection ways. For assemble rtd, there are connection heads and ceramic blocks that could be selected from. The purpose of various terminal enclosures is to meet dustproof, waterproof, flameproof, and other requirements. The choices are water-proof head, flame-proof head and display embed terminal head.
