Module for transformer hot spot monitoring

November 2018 Maintenance, Test & Measurement, Calibration

LumaSense Technologies has introduced the m924 utility module, designed for real-time transformer winding hot spot and temperature monitoring between -30 and 200°C. The module is specifically designed and optimised for transformer system monitoring providers and transformer manufacturers wanting to use Luxtron Fluoroptic DipTip and Quality fibre-optic temperature probes, cables, and tank wall plates in their equipment.

The Luxtron m924 utility module is a single printed circuit board offering four channels, which can be included in a transformer monitoring system. It offers RS-232 with ASCII and RS-485 with Modbus digital output for integration with standard PC or scada systems. In addition, it is guaranteed to be backward compatible with the Luxtron DipTip and Quality probes and all Luxtron accessories.

Unlike conventional winding temperature indicators (WTIs) that infer the hot spot temperature, this module measures the winding hot spot accurately and in real time without modelling. With instant results, controllers and pumps can act immediately to prevent transformer damage.

Leveraging LumaSense’s patented Fluoroptic technology and designed to replace the LumaSense m600 series utility modules, the m924 provides better performance with improved manufacturing and modern architecture. When combined with the Luxtron probes, the system provides precise and repeatable in situ temperature measurements and control of processes involving RF, EMI, magnetic fields and high voltages, while the small form makes it easy to integrate into existing equipment.

With over 40 years of fibre-optic temperature monitoring experience, LumaSense Technologies is a trusted provider of innovative temperature and gas sensing devices. By applying proven systems and software, customers in global energy, industrial materials and advanced technologies markets are able to reduce waste and inefficiency in their processes.
