1. Classification according to the way of engraving the disc is different
(1) Incremental type: that is, every time the viewpoint of the unit is rotated, a pulse signal is announced (there is also a sine and cosine signal, and then it is subdivided, and the pulse with a higher frequency is chopped), generally the output of phase A, phase B and Z, phase A and phase B are the pulse output that is delayed by 1/4 cycle of each other, and the difference can be reversed according to the postponement relationship, and the rising and falling edges of phase A and phase B can be doubled by 2 or 4 times; The Z-phase is a single-turn pulse, i.e. one pulse is announced per turn.
(2) **Value type: It corresponds to a circle, and the viewpoint of each reference announces a binary value corresponding to the viewpoint, and can be recorded and measured in multiple directions through external lap equipment.
2. According to the output type of the signal, it is divided into: voltage output, open collector output, push-pull complementary output and long-line drive output.
3. Classified by the mechanical installation of the encoder
(1) Shafted type: Shafted type can be divided into clamping flange type, synchronous flange type and servo mounting type.
(2) Bushing type: Bushing type can be divided into semi-empty type, full empty type and large-diameter type.
4. According to the working principle of the encoder, it can be divided into: photoelectric type, magnetoelectric type and contact brush type.

Precautions for load cell replacement – a blessing
The premise of load cell replacement is that the axis of the applied force coincides with the axis of the sensor, we should know one thing, that is, with the increase of the additional load, the microvolt/indexing signal output by the sensor decreases.
About the electromechanical junction of the S-shaped sensor installed in the second force transmission link ...

How to use different types of tension and compression sensors – we are blessed with blessings
Tension and compression sensors are one of the load cells. A device that converts physical data signals into accurately measured electronic signal outputs. It is widely used in industrial production weighing equipment, platform scales, electronic scales, hook scales, batching scales and other dynamometers. But different types of tension and compression sensors are used differently, and now ...

A little bit about photoelectric sensors – a blessing
Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...

We understand the object detection range of ultrasonic sensors
Autonomous mobile robot AMRs typically use LiDAR photoelectric sensors to detect objects. These photosensors emit light and rely on reflection to measure the distance to a specific surface. It's a great way to detect a solid object, but it can present challenges when it's surrounded by a transparent material such as glass. ...

No output problems with pressure transmitters – a blessing
1. Assuming that the pressure transmitter and the digital display are used together, and the digital display is not displayed at this time, then the user may say that the pressure transmitter has no output, but in fact, this problem is obvious, and it is unreasonable to hastily determine that the pressure transmitter has no output. Assuming the normal output of the pressure transmitter, ...

Typical construction of a smart sensor
A sensor is an input device that receives a signal or stimulus and responds to it. Some sensors now integrate many sensing elements and readout circuitry into a single silicon chip, which then provides high accuracy and multiple functions. The new sensor has more functions, including user friendliness.

Analysis of the use of various types of accelerometers
There are two types of accelerometers: one is the angular accelerometer, which is improved from gyroscopes. The other is a linear accelerometer. It can also be divided into single-axis, dual-axis and three-axis accelerometers according to the measurement axis.
At the moment, accelerometers are widely used in game controls.

The choice of accelerometers – Beggar
1. Analog output or digital output:
The first thing to pay attention to is the case of the analog and digital outputs, which is important because it is the interface between the system and the sensor. In general, the voltage of the analog output is proportional to the acceleration. For digital outputs, pulse-width modulated signals are typically used ...
