maintenance:
1) Always observe the sensor power cable and transmission cable (or wire) for damage and aging, and protect the rubber sheath outside the cable.
2) Periodically (usually half a year) use soft to not scrub the electrode surface to remove dirt or deposits.
3) Remove debris from the upstream straight channel section of the sensor.
Failure and its exclusion:
1) The liquid does not flow and has an output: 1. The signal transmission cable is disconnected from the converter; 2. The signal cable is disconnected from the electrode; 3. The electrode surface is contaminated or deposited with an insulating layer; 4. The grounding is poor or the circuit is broken.
Solution: 1. Connect the cable; 2. Open the sensor, reconnect it; 3. Scrub the electrode surface; 4. Connect the bottom line.
2) No flow of liquid flow: 1. The two wires of the signal transmission cable between the converter and the converter are reversed; 2. The power supply is not connected or the contact is poor; 3. The sensor has leaks in the pipe, the outer casing and the end face.
Solution: 1. Rewind the head; 2. Connect the power supply and keep the contact well; 3. Repair the sensor.
3) Unstable output: 1. The flow field is unstable; 2. The liquid passing through the sensor contains gas, large solid block; 3. The electrical connection is virtual; 4. The grounding is poor; 5. The electrode leakage solution: 1. Reconstruction Channel, or increase the installation of false sensors; 2. normal phenomenon; 3. check wiring, connect the line; 4. connect the ground wire; 5. repair the sensor.
4) The error is too large: 1. The zero point is too high; 2. The liquid is not completely filled; 3. The power supply is distorted too much; 4. The grounding is poor.
Solution: 1. Re-adjust the zero point; 2. Improve the channel conditions, the sensor is always full of liquid; 3. Improve the power supply conditions, in line with normal working conditions; 4. Connect the ground wire
Crystal head is an important interface equipment in network connection. It is a kind of plastic joint which can be inserted along the fixed direction and can automatically prevent falling off. It is used for network communication. It is named "crystal head" because of its crystal like appearance. It is mainly used to connect network card port, hub, switch, telephone, etc. The two ends of each twisted pair are connected with network card and hub (or switch) by installing crystal head.
