rotational speed measurement,
turbine speed sensor
Rotational speed sensor thermal expansion monitor DF9032 DEA, 0 - 10Hz frequency response
Turbine will be in the thermal expansion of the boot process, if uneven expansion of housing and infrastructure will make a huge stress between the oblique or tilt changes cause the enclosure, resulting in misalignment, if the sliding foot wedge tight enclosure to serious consequences.
DF9032 thermal expansion monitoring device can accept two LVDT (DC linear displacement transducer) signals to monitor the thermal deformation of the enclosure. LVDT installed in the chassis to be absolutely dead on both sides, both the deformation of the difference that case, you can set the alarm to prompt the operator to take early measures.
Range:-999.9mm ~ +999.9 mm;
Accuracy: ± 0.03mm;
Frequency Response: 0 ~ 10Hz, ± 1%
