  • Product Details
  • FAQs
Fluorescent fiber optic temperature measurement system, with customized number of temperature measurement channels according to customer needs, resistant to electromagnetic interference, especially used for temperature monitoring in power environments, such as switchgear temperature measurement, transformer winding temperature measurement, medical environment temperature measurement, experimental environment temperature monitoring, etc.

Fluorescent fiber optic temperature transmitter is a multi-channel fiber optic temperature measurement device. The temperature measurement channel can be expanded according to needs, and a standard RS485 communication interface can be provided to remotely transmit temperature information to the background and record and store temperature data. It is specially developed for real-time online temperature monitoring of power switchgear and ring main cabinets. Its internal modular integrated design allows for flexible installation and channel configuration, and can be externally connected to InnoTech standard LCD display instruments.

Functional characteristics
1、Separate design from LCD display for easy selection and matching
2、Provide dual RS485 communication interfaces
3、Integrated multi in one fiber optic module provides two sets of switch output functions
4、DIP switch settings for easy networking

General functions 1. Relay capacity: 5A/250VAC;
2. The over temperature alarm 1 value is 80 ℃. When the detected temperature is ≥ the over temperature alarm 1 value+0.1 ℃, the alarm I output contact will close; When the detection temperature is ≤ over temperature alarm 1 value -3.0 ℃, the output contact of Alarm I is disconnected;
3. The over temperature alarm 2 value is 120 ℃. When the detected temperature is ≥ the over temperature alarm 2 value+0.1 ℃, the alarm II output contact will close; When the detection temperature is ≤ over temperature alarm 2 value -3.0 ℃, the output contact of Alarm II is disconnected;
