The proximity sensor is a type of sensor that can detect an object that is near to it without any physical contact. This type of proximity sensor works on the principle of electrical induction, the inductive proximity sensors are used for an application that needs accurate non-contact detection of the metallic object so it is …
An encoder is a device that can convert the mechanical motion into an electrical signal, so basically, the encoder is a motion sensor device. We can use encoders to measure the length, position, speed, or angular position. So the encoder is an angular position sensor, the electrical signal which resembles the motion will be given …
An LVDT is an instrument that can be used to measure the linear displacement, LVDT stands for linear variable differential transformer basically it can be used to do the displacement measurement. This device is basically a transducer that can convert the linear motion into an electrical signal. An LVDT is an inductive transducer and it …
What are sensors on a robot and why are sensors important to robots The sensor is a device that could be mechanical chemical or electrical. The working of each sensor is based on the transduction principle which is energy conversion from one form to another. Sensors in robot allow it to react with its environment …

How Position Transducers WorkPosition transducers convert mechanical motion into an electrical signal that may be metered, recorded, or transmitted. Position transducers consist of a stainless steel extension cable wound on a threaded drum that is coupled to a precision rotary sensor such as an incremental encoder, absolute encoder, hybrid or conductive plastic rotary potentiometer, RVDT, …
Acceleration :Accelerometers measure acceleration, vibration, and shock. An accelerometer involves the mounting of a seismic mass attached to a damper and a spring inside a solid casing. Add caption The movement of the mass inside the casing is proportional to the force of acceleration on the device. Many accelerometers use either a capacitive or piezoelectric …
Quadrature Encoder Fundamentals : The most common type of incremental encoder uses two output channels (A and B) to sense position. Using two code tracks with sectors positioned 90 degrees out of phase, the two output channels of the quadrature encoder indicate both position and direction of rotation. If A leads B, for example, the disk is …
