Precimeasure 2220-R2 Remote Oil & Winding Temperature Indicator is an electronic temperature monitoring system designed for accurate remote indication of Top Oil Temperature (OTI) and Winding Temperature (WTI) in oil-filled power and distribution transformers. The system provides continuous temperature monitoring in the control room, helping utilities and transformer manufacturers monitor transformer health, prevent overheating, and improve operational reliability.
Model 2220-R2 works with a PT-100 RTD sensor and a Current Converter Unit (CCU) to convert temperature signals into dual isolated 4-20 mA outputs, making it suitable for SCADA, PLC, DCS, data loggers, annunciation panels, and remote monitoring systems. It is widely installed in substations, power plants, renewable energy projects, industrial facilities, and transformer manufacturing units where continuous transformer temperature monitoring is essential.
