There are many common questions and answers in the process of using the safe. The following summarizes common problems and solutions for everyone to use when you use the safe. You can save yourself a lot of unnecessary trouble!
Question 1, how to open a new safe to buy?
A: The newly purchased electronic lock safe has 4-6 keys. Two keys and a manual were attached to the door, and two other spare keys were placed in the safe. Remove the two keys on the door According to the operation diagram in the instruction manual, insert the big key into the main key hole, push the battery box cover to the right and insert the spare key. Both keys are rotated to the right to open the door. Follow the instructions.
Question 2. Newly purchased safe keys can also be turned but why can't the doors open?
A: Because the new safe is shipped from the factory in order to protect the paint on the door, there is a protective carpet in the lower left corner. When the key is turned to the open position, pull the big key handle to the left and pull the carpet out.
Question 3, how to change the password?
A: Open the safe to find the number change button behind the cover, press the escape button by hand to enter the new password when the green light is on, and then press the * key to confirm that the green light is off. Enter the new password Press # to exit.
Question 4: After the battery is replaced, why is the green light still on? Why not open it? Answer: There are two possibilities. One is that the customer's battery or battery is not enough.
Solution: Replace the battery that meets the standard. Second, press the password before turning the key to the right when inserting the key. The main electromagnet of the locking chuck card causes the key to turn out of position. Solution Insert a large key flat in a large key, enter the large key, and enter the password. Turn the key with the green light to turn on the safe door.
Precautions 1. In the case of battery undervoltage, the door cannot be opened and the battery must be replaced.
2. If the key is not inserted (screwed) into place, the door will not open and the key must be inserted (screwed) into place.
Third, if the bolt is loose, the door bolt fell into the door bolt sleeve, you need to contact professional after-sales service personnel to deal with the four, the spare key can not be used frequently, can only be used in emergency Emergency open method encountered the following situations 1, forget the password.
Solution: Use both the large key and the spare key at the same time. Turn the door together to set a new password.
2. The battery is dead. Solution: Insert a spare battery box on the outside and enter the password normally. ,

The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.
Liquid level transmitters can be applied to liquid Level Measurement and control in industrial sites, rural water supply and sewage treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, hydropower construction and other fields of liquid level measurement and control. Liquid level transmitters have input type, straight rod type, flange type, threaded type, inductive type, screw-in type, floating ball structure design, with anti-blocking type design, simple device, convenient use and strong interchangeability , The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes in the flow or static liquid level, and has high measurement accuracy.
Advantages of Level Transmitters
1. The device is simple, easy to use, and has strong interchangeability.
2. It is suitable for measuring the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
3. The reading is intuitive and eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4. The measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
6. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply, explosion-proof.
7. The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes of flowing or static liquid level, and has high measurement accuracy.
8. With intrinsically safe explosion-proof and isolated explosion-proof capabilities, it can be used in various dangerous places.
9. With anti-blocking design, it can realize the measurement of the liquid level of paste medium.
10.100% equal division scale, LED/LCD indicator head, very convenient to read on site.
11.4~20mA two-wire signal transmission, strong anti-interference ability and long transmission distance.
12. Exquisite and unique zero point, full scale, and nonlinear compensation ensure the accuracy and stability of the instrument within the range of operating conditions.
13. The Pressure Sensor directly senses the liquid level pressure and is not affected by the foaming and accumulation of the medium.
14. Wide range of tested media can be used, such as oil, water and paste, with certain anti-corrosion ability.
Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
