SF₆ Decomposition Detection Device 3-032-R050

Description

The DILO 3-032-R050 decomposition detector is a stand-alone device designed to quickly and accurately measure the amount of sulfur dioxide (SO­₂), and thionyl fluoride (SOF₂) in faulted SF₆.

Because the unit contains an automatic flow and pressure control module, the user does not need to be concerned with setting the correct flow rate, or compensating for variations in equipment pressure.  In fact, the device can handle up to 500 PSIG inlet pressure – making it a perfect fit for testing directly from cylinders, without the need for a (potentially contaminating) pressure regulator. All readings are displayed real-time on the touch-screen display, in parts per million by volume (PPM­_v­). 

The 3-032-R050 decomposition detector has been designed, from the ground up, to be used on arced SF₆.  Unlike conventional decomposition testers, which require expensive spectrometers or disposable detector tubes, this unit uses an electro-chemical sensor.  While the sensor must be replaced (by the user) every 12 months, its accuracy and sensitivity do not degrade due to use.   Calibration is not required. 

The universally accepted CIGRE B3.02.01 standard for re-usable SF₆ is currently 12 PPM_v­ for SO₂/SOF₂ – which falls well within the 0-100PPM_v range of the 3-032-R050
