Product Details

The VK series are non contact type eddy current sensors Displacement/ vibration sensors designed for rotating machinery such as compressors and power plant turbines. Model VK-A is a standard vibration transducer that confirms to API 670 Std 4th Edition. Model VK-P is available for measurement of differential expansion, which is indispensable for monitoring of large turbines. The VK-R series is available for power generating gas turbines which require long cable length.
Benefits
Intrinsic safety & explosion proof construction CSA, Atex, FMAnti corrosion, cannot be affected by lubrication oil or dust and options also available for ammonia, hydrogen sulphideFully compliant with API 670
