BW Sensor Repair UAE
• Catalytic diffusion sensors detect combustible gases and vapors by wounding wire into coils doped with catalysts.
• Sensors are connected to a Wheatstone bridge, detecting resistance changes.
• Active element burns the gas, increasing its temperature.
• Sensors must be intrinsically safe to prevent ignition.
• Electrochemical sensors detect and amplify current causing gas diffusion.
• Pressure gauges should be made from compatible materials or fitted with a diaphragm seal.
• Regular training on proper handling and installation can limit mishandling risk.
• Pressure gauges can be managed by standardizing, conducting audits, and coordinating employee training.
