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.

P+F precautions for the use of safety barriers
The safety barrier, also known as the safety energy limiter, is an important part of the intrinsic safety system. There are two main types of safety barriers: P+F Zener barriers and P+f barrier barriers. The core components of the Zener barrier are Zener diodes, current-limiting resistors and fast fuse wires.

Areas of application for flow sensors – we are blessed
Direction and fluid flow velocity sensors are essential for different industrial, medical, and environmental uses. Flow sensors quantify the direction and rate of gas and liquid flow in applications such as density measurement, viscosity measurement, flow pattern determination, and wall shear stress determination. In addition to the flow parameters to the direction, ...

Photoelectric switches for sensors
Photoelectric switches are what we generally call sensors. The definition of the sensor under the national standard GB7665-87 is: the equipment or device that can feel the specified measured parts and convert them into usable signals in accordance with certain rules, generally composed of sensitive elements and conversion elements.

The choice of torque transducer – we are blessed
1. Selection of reliability
The potential of a sensor to persist in its properties over a period of time is called reliability. In addition to its own structure, the key factor affecting the long-term reliability of the controller is the use of harsh environments.

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.

The wiring of the load cell – we are responsible
Load cells can be wired in two different input and output ways:
One 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 the time and time of use are very convenient, but when the cable is long, it is very simple to be affected by the working temperature.

Ultrasonic level gauge installation principle
1. The interval from the launch surface of the probe to the liquid level should be smaller than the range of the purchased surface.
2. The interval between the launch surface of the probe and the highest liquid level should be greater than the blind area of the purchased surface.
3. The launch surface of the probe should be parallel to the surface of the liquid.

The correct way to test the output of the sensor – the sensor
1. Test for NPN output sensor
The NPN sensor output, also known as OC gate output, is based on the principle of open collector output of a transistor.
The principle of NPN type OC gate output is whether the output of the NPN transistor and GND are short-circuited. When the control is active, the transistor is turned on, the output and the GND ...

Points to note for encoder installation
1. Each electrical interface has its own characteristics, but also has different baud rate and transmission interval, which can be selected according to the specific application environment of the site, and the actual transmission interval is very related to the transmission rate, encoder and communication cable installation disturbance environment, grounding, cable material selection, etc.
