The Rapidox SF6 6100 Portable is designed for controlling and monitoring the quality of SF6 in MV & HV gas insulated electrical equipment. Exceptional accuracy and stability are provided when measuring the purity of SF6 gas, through specially selected sensors. A gas output nozzle allows for the analyser to be attached to the Rapidox Gas Recovery Bag, ensuring that all sampled SF6 gas is recovered.
Internal SF6 gas pressure is recorded and logged by the analyser. All measured gases are analysed and data-logged simultaneously with only a few minutes required to achieve a stable reading. In order to accelerate the time taken in-between dew point readings, a unique Rapidri system is fitted to analysers measuring H2O. When not in use the sensor can be isolated via the Run Storage valve.
Other measurable gases include H2O (dew point), SO2, HF, O2 & CF4. Due to the instruments modular design, a number of configurations are available in order to suit a variety of application requirements.
Features
Sensor | Specification | Accuracy | Calibration | Life Span | Sensor Type |
SF6 Sulphur Hexafluoride | 0-100% | 0.5% accuracy | Every 12 months | >5 years | Infrared (IR) |
H2O Dew Point | -60oC to +20oCdp (10 24,000ppmV) Reading is corrected to either RT or 20oC |
2oCdp of reading | Every 12 months by Sensor Exchange | 2-3 years | Polymer |
SO2 Sulphur Dioxide | 0-100ppm OR 0-500ppm | 2% full-scale | Every 12 months | 2-3 years | Electrochemical |
HF Hydrogen Fluoride | 0-10ppm OR 0-30ppm | 2% full-scale | Every 12 months (Using HCI gas) | 2-3 years | Electrochemical |
CF4* Tetrafluoromethane | 0-80% | 1% of full reading | N/A | N/A | (measured by balance of SF6 + Air reading) |
H2S Hydrogen Sulphide | 0-100ppm | 2% full-scale | Every 12 months | 2-3 years | Electrochemical |
CO Carbon Monoxide | 0-1,000ppm | 2% full-scale | Every 12 months | 2-3 years | Electrochemical |
Air / N2 Nitrogen | 0-100% | full-scale based on oxygen component | Every 12 months | 2-3 years | Electrochemical O2 scaled to read as Air or Nitrogen |
*For analysers containing a CF4 sensor, the measurement of Air is also a requirement.
Rapidox SF6 6100 Accessories
A range of accessories is available for the Rapidox SF6 6100 gas analysers. These include special tongue and groove self sealing couplings (compatible with famous brands) as well as a range of stainless steel braided sampling hoses for use with SF6 gas-insulated equipment.
The Rapidox SF6 6100 Bench analyser is also available as a complete and portable kit that allows users to carry all of their required equipment within a heavy-duty IP66 case. Each kit contains a set of fittings with a stainless steel braided hose, a handle fitted to the analyser and a separate thermal printer.
Regular calibration significantly increases the measurement reliability and repeatability of gas analysis equipment. Cambridge Sensotec is able to offer a full calibration service at its factory via state-of-the-art automated calibration stations, designed to calibrate Rapidox gas analysers accurately and The Rapidox SF6 6100 Pump Back is the latest in fully-automatic gas analysers, designed for controlling and monitoring the quality of SF6 in medium & high voltage gas insulated electrical equipment. Exceptional accuracy and stability are provided when measuring the purity of SF6 gas, through specially selected sensors.
Once connected, the Rapidox SF6 6100 Pump Back samples gas from the electrical equipment automatically or manually, with an inlet auto gas pressure sensing function. A vacuum purge cycle and gas storage system ensures that no air can contaminate the gas sample and that no SF6 gas is able to escape during the testing period.
SF6 gas pressure in the internal sample compartment is recorded and logged by the analyser. All measured gases are analysed and data-logged simultaneously with only a few minutes required to achieve a stable reading. A powerful 10 bar compressor, with a separate lithium battery power supply, then returns the gas efficiently. Insured worldwide return shipping is available.
