The Precimeasure Model 2243A Combined OTI-WTI Scanner is a trusted transformer monitoring device designed for continuous supervision of both Oil Temperature Indicator (OTI) and Winding Temperature Indicator (WTI) functions in oil-filled transformers. Based on PT-100 sensor technology, this scanner helps operators monitor critical transformer temperatures from a central location, supporting safe operation and improved maintenance planning.
Used extensively in power transformers, distribution transformers, substations, utility networks, industrial plants, and infrastructure projects, the Precimeasure 2243A provides dependable temperature monitoring for applications where transformer reliability is essential. By displaying oil and winding temperature information in an easy-to-monitor format, the system assists maintenance teams in detecting abnormal operating conditions before they lead to unplanned downtime.
The Model 2243A is widely specified by transformer manufacturers, panel builders, EPC contractors, utilities, and industrial users seeking a practical and effective transformer temperature monitoring solution. Its compatibility with modern control systems also makes it suitable for integration into transformer automation and SCADA environments.
 
Why Transformer Temperature Monitoring Matters
Temperature is one of the most important indicators of transformer health. Excessive oil or winding temperatures can accelerate insulation ageing, reduce transformer life expectancy, and increase the risk of unexpected failures.
A combined OTI-WTI scanner allows operators to monitor these critical parameters from a single device, helping them:
Improve transformer operational reliability
Detect abnormal temperature rises at an early stage
Support preventive and predictive maintenance programmes
Reduce the likelihood of costly shutdowns
Enhance asset management practices
Improve safety within electrical installations
Monitor transformer performance more effectively
By providing a clear view of transformer operating conditions, the Precimeasure 2243A contributes to better decision-making and long-term equipment protection.
