OH series of Inductive Pickups are used to measure the speed of engines, such as diesel engine, gasoline engine and steam turbine. It can detect gear, crankshaft, rotating spokes, no need of power supply and without any excitation circuit from control device.
They can be equivalents of similar sensors from America WOODWARD
|The detection distance (between sensitive head and gear vertical distance range||0.25 ~ 1.02mm||Working temperature||-10 ~ +125 C|
|Diameter of gear||less than 0.51mm||DC resistance||190 + 10Ω (25℃)|
|Measuring range||70 ~ 99999 rpm||Anti-vibration||20g|
|The output frequency||HZ= gear tooth number: * speed /60|
|Output voltage||1 ~ 30V sine wave signal (output voltage increases with speed ,increasing the output voltage with the air gap increases, depending on gear relative to the output voltage waveform of sensitive head size and shape)|
