The pulse encoder is a rotary encoder that uses the rotation pulse for signal output, and the main characteristics are the standard shape and diversified shape structure; The internal coding is stable, the signal output qiang, and the pulse value and positioning value are clear. Therefore, when selecting this type of punch encoder, it is necessary to correctly identify the pulse positioning number of the encoder. Then I will introduce to you in detail how to identify the pulse positioning number of the encoder.
The number of pulses of a rotary encoder is mainly determined by the structure of the internal fluctuating disk, and the number of pulses will be different depending on the structure when rolling the encoder. The identification of the number of pulses requires the help of professional testing tools, which are mainly tested and recognized by the manufacturer. The customer can request the required number of pulses directly from the manufacturer. The number of positions refers to the total number of stuck points (positioning) in the rolling circle of the rotary encoder, and the number of positions can be recognized by the encoder on the rolling hand.
Steps: 1. Start with a fixed point
2. Gradually roll a circle 360 degrees
3. How many stuck points (positioning) there are in this process of perceiving scrolling by hand.
After confirming the number of positions, the number of pulses can be selected according to the operating principle of the encoder. First of all, there are two types of relationship between pulse and positioning. DIN 1 is a pulse for the encoder to roll one bar (one position), and the second is for the encoder to roll two spaces (two positions) to generate a pulse. Then, according to the previously recognized positioning number, you can correctly identify the pulse number of the encoder according to the required operating principle.

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. ...

How to deal with the malfunction of the proximity sensor during work
What is the reason for the detection signal when no metal object is close to the switch?
The magnitude of the electromagnetically induced voltage is proportional to the current of the disturbance source, that is, the larger the disturbance current, the greater the disturbance voltage. If the proximity switch does not adopt any ...

Wiring of weighing strain gauge tension and compression sensors – we are in control
Strain gauge tension and compression load cells are available in two different input and output wiring methods:
The first is the four-wire connection method.
The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

P+F proximity switch selection points
1. Select the proximity switch type according to the detected object. If the detection object is metal, the inductive proximity switch is preferred, and if the detection object is a non-metal such as wood, plastic, paper, water, etc., or a smaller and finer metal, a capacitive proximity switch should be selected.

Pressure Transmitter Verification Regulations
A pressure transmitter is a type of instrument that converts a pressure variable into a consistent output signal that can be transmitted, and there is a given continuous function relationship between the output signal and the pressure variable, which is generally a linear function. Pressure variables include positive and negative pressure, differential pressure and pressure. Pressure transmitters are available in electric and ...

Sensor calibration method – Blessing Blessing
Sensor calibration refers to the process of transmitting the standard value expressed by the norm to the indexing of the sensor's operating range, and the indexing is determined.
The calibration of the sensor is based on the standard value generated by a standard device (e.g. a known standard force, pressure, torque, displacement, etc.).

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, ...

The main role of the encoder is explained - double blessing
An encoder is a device that converts angular or linear displacement into an electrical signal. The former becomes the yardstick, and the latter is called the yardstick. According to the readout method, the encoder can be divided into two types: touch type and non-touch type. The touch type selects the brush output, and a brush touches the conductive area or the insulating area to represent the shape of the code.
