Scanners are Microprocessor based electronic instruments for various applications like Transformer Oil Temperature Monitoring and Bearing Temperature monitoring, etc... Instruments with capability of sensing RTD and Thermocouple are available. Optional data logging features are also available.

This Scanners used to indicate and Control Oil & Winding Temperature of the oil – immersed transformers. 6 Relays are provided for Alarm, Trip and Cooler functions and operate as per the set value. 4-20mA DC signal outputs are provided separately for OTI & WTI for Remote Indication or SCADA purpose. The System has the capability to store the maximum temperature attained.
