Products Description

Our transformer temperature monitoring system uses dielectric optical probes that are immune to electromagnetic interference. The monitor converts probe response into temperature data, alarm outputs, analog signals, and digital communications.

Technical Principle

Dielectric optical probes are installed at the required hot spots. Temperature changes alter the optical response of the sensing material, and the monitor converts this response into a stable temperature value. Because the measuring path is optical rather than metallic, it remains suitable for strong electric and magnetic fields.

Product Features

The transformer temperature monitoring system measures temperature with dielectric probes inside strong electric and magnetic fields. Two optical principles cover different temperature ranges and sensing preferences. Multi-channel architecture supports several winding or structural hot spots. Analog, relay, serial, and optional network outputs simplify control-system connection.

Operating Conditions

Install the product in a clean, ventilated location without corrosive gas, conductive dust, water ingress, severe vibration, or strong impact. Provide reliable protective grounding, maintain the required electrical clearances, and use the rated auxiliary power supply. Confirm ambient temperature, humidity, altitude, enclosure protection, cable routing, and communication conditions before production and installation.
