Switchgear Temperature Monitoring
OSENSA’s cost-effective fiber optic temperature sensors provide continuous real-time monitoring of switchgear temperature at critical contact points to quickly detect overload and fault conditions. OSENSA’s FTX series temperature transmitters offer both analog output and RS-485 Modbus communication for simple integration with existing PLCs (Programmable Logic Controllers) and host monitoring software. OSENSA’s optical temperature sensors provide years of accurate sensing to ensure safe and efficient switchgear operation.

Advantages of OSENSA's Fiber Optic Temperature Sensors for Switchgear Monitoring
OSENSA’s fiber optic temperature sensors do not suffer any of the technical challenges associated with wireless and infrared thermometers. Fiber optic sensors can be routed directly to critical switchgear monitoring points. OSENSA’s low-cost optical temperature sensors are rigidly attached to hot-spot locations and are completely immune to electromagnetic interference and noise bursts caused by high-voltage switching. OSENSA’s fiber optic sensors are robust, can be manufactured to various lengths, and work like a conventional thermocouple. Each OSENSA optical temperature sensor transmitter can monitor three phases providing both analog output and digital RS-485 Modbus RTU communication. OSENSA’s fiber optic temperature probes are perfectly suited for smart grid switchgear temperature monitoring.

Thermal Protection for Continuous Monitoring of Generators and Motors

Fiber optic temperature sensors are now routinely installed into large motor and power generator equipment to provide real-time monitoring and thermal protection of critical stator windings, circuit rings and bearing hot spots. OSENSA’s PWR+ Temperature Monitoring Solutions provide continuous, real-time temperature monitoring of windings and connection points in generators and motors. The rugged and inherently safe temperature probes accurately and instantaneously measure temperatures up to 200°C and will last the life of the generator or motor without replacement. Typical utility-sized generators or motors may contain as dozens of measurement points. Temperatures can be monitored and logged real-time with either the HMI-100 Display and Control Module, or with the TCU-300 Temperature Control Unit, with alarms for identifying temperature concerns and alerting appropriate personnel. Alternatively, the temperature transmitters can be embedded into an RTU, PLC or other control or monitoring system.
