Dial Type OTI Meter

Product Details:

An Oil Temperature Indicator (OTI) is a device that measures and displays the temperature of insulating oil in equipment like transformers or engines, crucial for preventing overheating by providing real-time readings, triggering alarms, and controlling cooling systems to protect against damage and ensure efficiency. It works by sensing the hot oil, often using a bulb and liquid expansion, to drive a pointer on a dial, with modern versions offering digital displays and communication.
