The WIKA TG53 bimetal thermometer provides direct, local temperature indication without requiring an external power supply. Its process-grade construction is designed for industrial environments where mechanical durability, readability, and dependable temperature monitoring are important.

The thermometer is available in different configurations to accommodate installation requirements, including axial connection and versions with an adjustable stem and dial. Optional materials and damping features can be selected according to the process conditions.

Key Features

• Process-grade design: Manufactured in accordance with ASME B40.200.
• Accuracy: ±1% of full scale, Grade A.
• Environmental protection: Hermetically sealed case with IP66 (NEMA 4X) protection.
• Vibration resistance: Optional damping arrangements help reduce pointer oscillation in high-vibration environments.
• Easy-to-read dial: Dished dial design helps reduce parallax reading errors.
• External adjustment: Rear reset screw allows limited adjustment of the reference temperature.
• Flexible installation: Different stem lengths and connection configurations are available.
• Material options: 316 stainless steel construction is available for selected configurations.

Suitable Applications

• Chemical and petrochemical plants: Local temperature monitoring of process equipment and piping.
• Oil and gas facilities: Temperature indication in demanding process environments.
• Power generation: Monitoring temperatures in industrial systems and auxiliary equipment.
• Water and wastewater treatment: Temperature measurement in process pipelines and equipment.
• High-vibration installations: Applications where vibration damping can help maintain a stable, readable pointer.
• Harsh outdoor environments: Installations requiring a robust enclosure with IP66 protection.

Technical Highlights & Selection Considerations

When selecting a WIKA TG53, confirm the following details to ensure the thermometer matches the installation:

• Measuring range: Select a temperature range appropriate for normal operating conditions and expected temperature extremes.
• Dial size: Confirm the required dial diameter and readability for the installation location.
• Stem length and diameter: Match the insertion dimensions to the pipe, vessel, or equipment being measured.
• Process connection: Verify the connection type and dimensions required by the installation.
• Mounting arrangement: Specify axial connection or an adjustable stem-and-dial configuration as appropriate.
• Wetted materials: Consider whether stainless steel or optional 316 stainless steel components are required by the process medium and environment.
• Vibration damping: Consider a suitable damping option where significant mechanical vibration may affect pointer stability.
• Protection and standards: Confirm the required environmental protection and applicable project specifications.

Important: The exact measuring range, stem dimensions, dial size, connection, and material depend on the selected configuration. Check the WIKA datasheet and order code before purchasing.

FAQ

Q1: What type of instrument is the WIKA TG53?

The TG53 is a mechanical bimetal thermometer for direct temperature indication in industrial processes.

Q2: Does the TG53 require an external power supply?

No. It uses a bimetal measuring mechanism and does not require an external electrical supply for local indication.

Q3: Is the TG53 suitable for high-vibration environments?

Yes. WIKA offers damping options designed to reduce pointer oscillation under severe vibration conditions. The appropriate configuration should be selected for the actual installation.

Q4: Can the TG53 be used in corrosive or aggressive environments?

It is designed for demanding process applications. Selected versions offer 316 stainless steel construction, but material compatibility must be checked against the specific process medium and operating conditions.

Q5: What information is needed to order the correct TG53?

Provide the required measuring range, dial size, stem length and diameter, process connection, mounting arrangement, material requirements, and any vibration-damping or certification requirements.
