High quality, Gaas-based temperature sensing
Dresden, Germany — Due to the growing demand of energy existing power plants and grids are stretched to their limits. To ensure operational safety, critical factors such as temperature has to be monitored in generators and transformers. High power generators are often filled with hydrogen in order to cool effectively. Besides the heavily contaminated electromagnetic environment, the risk for explosions is high.
Optocon AG offer a variety of fiber optic temperature measuring devices, fiber optic temperature sensors and accessories for temperature monitoring in oil-filled power transformers. You can enjoy all the benefits of the fiber optic measurement principle.
The outer jacket of the fiber optic temperature sensor is made out of PTFE, at the sensor tip a GaAs-crystal (gallium arsenide) is attached. The GaAs based technology is ideal for smart grid temperature monitoring in transformers.
The probe sensor is completely non-conductive.
Optocon’s fiber optic temperature sensors offer complete immunity to RFI and EMI emmisions with high temperature operating capability, intrinsic safety, and non-invasive use. The fiber optic temperature sensors are also designed to withstand harsh and corrosive environments.
High quality, Gaas-based temperature sensing systems
The FOTEMP temperature signal conditioners are user-friendly and easy to operate. The high system accuracy of +/- 1 °C as well as fast sampling rate per channel offer reliable real-time temperature results.
With their wide portfolio of signal conditioners a versatile usage is possible, e.g. the FOTEMP1-H with wireless module allows walk-as-you-go easy temperature validation of the transformer assembly. FOTEMP-MK-19″ offers simultaneous fast readout of the channels, within a flexible and expandable system, 2-4-6..16..255 measurement channels.
All signal conditioners come with standard analog output and RS-232, RS485 or ModBus communication port for real-time data acquisition. Relays and other analog output option are available on request. They can be controlled via the LCD display and via the “FOTEMP-Assistant” software.
The fiber optic temperature sensor provides accurate, stable and repeatable measurement results. Optocon’s sensors offer complete immunity to RFI, EMI, NMR and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The TSNANO temperature sensor stands out for it’s miniature size and can be self assembled with the NANO-Kit.
With the protective spiral wrap sensor hose the sensor is protected against oil damage and prevents sparks. The sensor cable can be up to several meters long without influencing the accuracy of the measurement result. All sensors come with ST-connector to feedthrough. Other connector types are available on request.
These optical feedthroughs are specifically designed for installation on tank walls and oil transformers. They have a leak-proof interface and require no maintenance. On both sides are standard ST connector. There are no moving parts or loose optical cables.
They can withstand pressures up to max. 16 bar (200 psi). The stainless steel tank wall plate is installed outside the transformer wall to protect and guard the fiber optic measurement assembly. The rough extension cables can be used on all fiber optic temperature sensors.
Optocon AG offers a complete range of signal conditioners for fiber optical temperature measurement, fiber optic temperature sensors and probes and fibre optical accessories that can be adapted to your specific requirements. The fiber-optic temperature measurement method is becoming increasingly important in high electromagnetic interfered environment, in microwave fields and other environments, where measurement with electric temperature sensors is not possible. Optocon’s fiber-optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The fiber optic probes are also designed to withstand harsh and corrosive environments.
