Analysis of the causes of the problems encountered by P+F in the use of encoders:
1. Grating pollution This will reduce the signal output amplitude, and the oil must be quietly wiped off with absorbent cotton dipped in anhydrous alcohol.
2. Encoder connection cable failure: the probability of this fault is high, and it is often encountered in maintenance, so it should be a priority element. Generally, the encoder cable is open, short-circuited, or in poor contact, and the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is not tightly fixed, causing loosening and causing open welding or breaking, and the cable needs to be clamped tightly.
3. Encoder self-failure: It refers to the problem of the encoder's own components, resulting in its failure to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired.
4. Encoder battery voltage drops: this fault generally has a meaningful and clear alarm, at this time the battery needs to be replaced, if the reference point azimuth recall is lost, it is necessary to perform the operation of returning to the reference point.
5. Encoder +5V power supply decline: refers to the +5V power supply is too low, generally not lower than 4.75V, the reason for the low is that the power supply is faulty or the power transmission cable resistance is too large and causes loss, then the power supply needs to be repaired or the cable replaced.
6. Loose encoder installation: This problem will affect the accuracy of azimuth control, resulting in the deviation of the azimuth error in stopping and moving, and even the servo system overload alarm occurs as soon as the machine is turned on, please pay special attention.
7. Encoder self-failure: It refers to the failure of the encoder's own components, resulting in its failure to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired.

There are three types of P+F proximity switches
P+F proximity switches can be divided into three varieties:
1. Capacitive proximity switch can detect metal and non-metal objects with an induction scale of 1-40mm
Capacitive proximity switches detect both metallic and non-metallic objects. ...

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.

Introduction to the throttle azimuth sensor – Doubleblessed
What is the function of the throttle orientation sensor?
The primary function of the throttle azimuth sensor is to detect whether the starting motor is in the idle condition or the load condition, and whether it is in the acceleration condition or the deceleration condition. The shaft of the resistor is linked to the throttle, it has two contacts: a fully open contact and an idle ...

The wiring method of the photoelectric switch
P+F photoelectric proximity switch is called a photoelectric switch made of the photoelectric effect. The light-emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) is close to each other, the photoelectric device receives the reflected light and outputs it in the signal, so that it can be "...

The key factor influencing sensor performance – the company
Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer.

Precautions for pressure sensors – a blessing
1. Avoid scum deposited in the catheter and contact the transmitter with corrosive or overheated media.
2. When measuring the gas pressure, the pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

Important features of our sensors
On the linear scale of our sensors, the higher the sensitivity, the better. Because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and the external noise that is not related to the measurement is also simple.
