Non-Contacting Speed Sensor in The Braking Signaling Traction System of Rail Transit Vehicles Rail Transit Vehicles

GHS1 series speed sensor General descriptionSeries speed sensor is a device specifically designed to meet the needs of the rail transit vehicles operation. Based on the mechanism of the Hall effect, it provides stable and reliable signal for speed recording systems of rail vehicle such as traction system, braking system, monitoring system, etc. Sensor is usually installed on the housing or end enclosure of rotating device of all kinds of rail vehicles, and the measuring rotational object is a magnetic conductive speed-measuring gear.      Electrical parameters   Operating temp.Industrial grade:-40ºC~+85ºC,   High temperature grade:-40ºC~+120ºCStorage temp.Industrial grade:-40ºC~+85ºC,   High temperature grade:-40ºC~+120ºCRelative humidity0~100%Operational speed0Hz~20kHzSpeed-measuring gearStandard involute gear: modulus not less than 0.25, 20° pressure angle, the magnetic material of low carbon steelWorking air gapWorking air gapSupply voltage10Vdc ~30Vdc, Ripple wave≤2%Load resistance≥1kΩNumber of the Output channels1, 2, or 4 (Customized on request)Output waveformSquare waveHigh level≥0.8Vcc (Load resistance 1kΩ)Low level≤0.1V (Load resistance 1kΩ)Rise time≤3.0μsFall time≤3.0μsDuty cycle50%±20%Phase shift90°±30°Current consumption without load≤40mA (Each signal channel)Insulation resistance≥100MΩ (500V Megohmmeter)Dielectric strength2000Vr.m.s/50Hz/60s,Leakage current≤3mAEMCAccording to the standard EN50121-3-2:2006Mechanical parameters   Protection degreesMetal housing parts of the sensor: IP68Vibration30g, Random vibrationShock100g (Pulse width 6ms, half-sine wave)Housing materialHigh strength stainless steelSensing coreThe front end of the sensing core is hermetically sealed, and all electronic components are encapsulated in the epoxy potting with good performance of vibration resistance, impact-proof, anti-aging and perfect sealing.Weight1.5kg (Cable length 2m)Mounting torqueStainless steel hexagon head bolt M8X30: 20(1±20%)N·m   Stainless steel hexagon head bolt M6X12: 8(1±20%)N·mOur Service1.
