High temperature resistant electronic crane scales are widely used for weighing in high temperature environments. Why is the high temperature resistant electronic crane scale resistant to high temperatures?
First of all, we must understand the principle of high temperature electronic crane scale :
When the load of the electronic hook scale acts on the sensor through the hook, the elastic body of the sensor is slightly changed, so that the resistance value of the resistance strain gauge attached to the elastic body changes, and the balance of the bridge is changed. The output voltage is changed, and the changed voltage signal is converted into a digital signal by a high-speed and high-precision A/D converter, and the digital signal is transmitted to the secondary meter via a collector, a wireless transmitter (or a cable). The secondary instrument performs the data calibration process on the obtained signal, and sends the corresponding weight value to the display screen. It can also be printed by the printer and transferred to the computer management system if necessary.
Among them, the electronic hook scale adopts a special sensor for the special thermal electronic hook scale to ensure better accuracy under high temperature environment. Add high temperature insulation board to effectively block heat source radiation. And a heat insulation layer is added to the body cavity to further block the penetration of the heat source.
Product use precautions:
1. Use the operation:
(1) Overloading is strictly prohibited.
(2) When lifting heavy objects, it must be lifted vertically, and it is forbidden to drag heavy objects through the scale body.
(3) When using the crane scale, the operator should keep a certain distance from the object to be lifted to prevent the object from accidentally falling and causing harm to the human body.
(4) Before using the crane scale, check whether the screws, hooks, rings and split pins are loose, loose, deformed or worn to ensure safe use. It also provides routine maintenance and inspection work.
(5) Charger Please use the special charger we provide for you. Improper use of the charger may cause overcharging of the battery, shorten the battery life and even endanger the safety.
(6) When adjusting the handle of the instrument, please use both sides to pull out evenly and allow rotation to a convenient angle.
(7) In the instrument, you need to enter the password before you can perform the functions of the latter operation. Non-professional test personnel are not allowed to enter the operation without authorization. Therefore, the company will not bear any adverse consequences.
2. Use environment:
(1) Hanging scales are precision measuring instruments rather than general spreaders and locks. Therefore, when not used for metering, please store them in a cool dry place.
(2) The crane scale can not work in high temperature environment for a long time. When using high temperature source on site, even if high temperature insulation device is used, attention should be paid to shorten the residence time as much as possible. The general principle is that if the bottom surface of the scale body is not hot to touch ( Below 70 ° C) will not adversely affect the crane scale.
(3) The scale body should pay great attention to avoid violent collision and rainwater immersion. In particular, it should be taken to prevent the scale body from falling off the hook, causing damage to the scale body and even personal accidents.
3. Maintenance:
(1) The crane scale is powered by battery, and should avoid excessive voltage use during use, otherwise the battery life will be shortened. In principle, please try to do it. When the scale body stops working for more than two, please remove the scale battery and the meter will stop working for more than one week to turn off the meter power switch. Storage is not used. For more than one month, you must ensure that the scale battery and instrument battery are charged once a month.
(2) In order to extend the battery life, the backlight of the instrument is turned off during the daytime use.
(3) It is strictly forbidden to use strong solvents (such as benzene and nitro oil) to clean the crane scale. For cleaning, use a soft, lint-free cloth dampened with water and then a mild detergent (soap) for cleaning. After cleaning, please dry the hanging scale carefully with a dry, lint-free cloth. To prevent corrosion and damage to the crane scale, to ensure safety.
(4) If the product is alive, the company will continue to introduce new products, and the new products may differ from the instructions. Please understand.
(5) When the use of the crane scale fails, please inform our professional engineers to check and organize in time, the user shall not disassemble the chassis at will, and the internal parts shall not be replaced at will; the operator and the instrument maintenance personnel shall go through special training to operate and service.
