Abstract: A 4-probe laser interferometric displacement sensor (4pLIDS) has advantages over a single-probe LIDS in a micro-thruster calibration system. By synchronously measuring the displacements at ...

2 shows the circuit diagram ... If any jumper wire was disconnected (or broken), the corresponding LED did not blink, indicating a fault. The continuity tester operates using the CD4047, a ...

Abstract: This paper proposes an intensity-modulated liquid level sensor based on cascaded long-period fiber grating (LPFG) and fiber Bragg grating (FBG) structure with temperature compensation. Its ...
