Frequently Asked Questions

Q1: What is the WIKA TG54 used for?

It is used for direct local temperature measurement in industrial processes, particularly where rugged construction and reliable visual indication are required.

Q2: Does the TG54 require an external power supply?

No. It uses a mechanical bimetal measuring system and does not require external electrical power for temperature indication.

Q3: Is the TG54 suitable for high-vibration environments?

Yes. WIKA identifies the TG54 as suitable for applications with high vibration. The installation conditions should still be checked when selecting the instrument.

Q4: What dial sizes are available?

The TG54 is available in nominal dial sizes of 63, 80, 100 and 160 mm.

Q5: Is a 316L stainless steel version available?

Yes. The case, stem and process connection can be specified in 316L stainless steel as optional configurations.

Q6: What information should I provide when ordering?

Provide the required measuring range, dial size, mounting arrangement, process connection, stem dimensions and material requirements. Confirm the exact configuration against the application and manufacturer’s datasheet.
