Product Description

This precisely developed Transformer Winding Temperature Indicator has IP55 protection rating and it can be operated under -40 degree C to 55degree C temperature range. This type of temperature indicator is needed to safeguard transformer against overheating. It is capable of registering highest temperature rise of transformer windings and oil. This product is also capable to trip circuit breaker of transformer. Cooling mechanism of transformer is also regulated by such Transformer Winding Temperature Indicator. It comprises of sensing bulb which is located inside oil filled pocket of transformer tank. Highly flexible capillary tubes are used to connect this bulb with the housing of transformer. Quality of this product has been verified on the basis of its strength, longevity, design and mechanism.



Exceptional Temperature Monitoring Accuracy

Delivering high sensory accuracy (1.5% of FSD), this temperature indicator helps maintain transformer safety and efficient operation. The liquid-filled Bourdon tube system provides reliable measurement under varying load and ambient conditions.


Flexible Installation & Robust Design

The indicator supports multiple mounting options: panel, surface, or flush, accommodating diverse transformer configurations. Its IP55-rated, die-cast aluminum body and shatterproof polycarbonate window ensure durability in demanding industrial or outdoor settings.


Customizable and User-Friendly Operation

With 1 to 4 adjustable switches and set points, manual or automatic reset, and a variety of sensor capillary lengths (up to 12m), the device caters to different transformer sizes and requirements. Screw-type brass terminals facilitate secure electrical connections, making installation and usage straightforward.

FAQs of Transformer Winding Temperature Indicator:


Q: How does the Transformer Winding Temperature Indicator operate?

A: It uses a liquid-filled Bourdon tube system to sense winding temperature through an external sensor, relaying measurements via a pointer on the dial. The device triggers electrical switches at user-adjustable set points, enabling precise monitoring and control.

Q: What benefits does adjustable set point switching offer?

A: Adjustable set point switches (1 to 4) allow users to customize alarm or control trigger levels for specific transformer requirements, enhancing operational safety and early fault detection.

Q: Where can this temperature indicator be installed?

A: This device can be mounted on panels, surfaces, or flush within transformer units. Its IP55 enclosure ensures weatherproof protection, making it suitable for both indoor and outdoor transformer installations.

Q: When should the reset mechanism be used?

A: Use the manual or automatic reset option to restore switch action after error resolution or temperature normalization. This ensures the indicator is always ready for accurate temperature monitoring.

Q: What is the process for connecting the sensor and electrical terminals?

A: The sensor comes with a standard 2.5m capillary tube, extendable up to 12m. Screw-type brass terminals provide reliable electrical connections to transformer control or alarm circuits. Follow wiring diagrams for secure, compliant installation.

Q: What safety and performance standards does the product meet?

A: It complies with IS 335 / IEC 60076 standards, offering high vibration resistance and reliable operation in temperatures from -20C to +120C. The robust enclosure and shatterproof window enhance safety and durability under industrial conditions.

Q: How does using this indicator benefit transformer maintenance?

A: Early detection of winding overheating helps prevent transformer failures, extends equipment life, and avoids costly downtime. Accurate temperature monitoring is essential for optimal transformer performance and safety.
