- MORE 產(chǎn)品快速導(dǎo)航
SLK801壓力變送器 稱(chēng)重傳感器是在現(xiàn)實(shí)生活中應(yīng)用最多的一種傳感器,很多尋常百姓家里都可以看見(jiàn),今天我們來(lái)說(shuō)說(shuō)工業(yè)上應(yīng)用的產(chǎn)品。稱(chēng)重傳感器本身具有結(jié)構(gòu)牢固、經(jīng)久耐用的優(yōu)點(diǎn)，但是在使用安裝過(guò)程當(dāng)中如果不注意的話(huà)，也會(huì)影響它性能的發(fā)揮。
對(duì)于小計(jì)量的傳感器，應(yīng)該避免它受到?jīng)_擊，這會(huì)影響到它今后測(cè)量值的準(zhǔn)確性。大計(jì)量的產(chǎn)品本身重要比較重，搬運(yùn)的時(shí)候最好使用專(zhuān)用的搬運(yùn)工具，落到地面的時(shí)候要減緩速度，避免震動(dòng)對(duì)它里面器件造成損壞，同時(shí)安裝基座要水平放置，底部要清掃干凈，不能有雜物存在。任何稱(chēng)重傳感器在使用過(guò)程中需避免超載測(cè)量，這會(huì)導(dǎo)致彈性體形變不可恢復(fù)，造成永久損壞。
傳感器在水平調(diào)整過(guò)程中，最好使用水平儀，使得安裝的傳感器在統(tǒng)一水平面上，保證其所受負(fù)荷的一致性。
傳感器要采用螺栓固定，保證一定的緊固力矩，長(zhǎng)時(shí)間使用不會(huì)松動(dòng)。
傳感器的安裝位置盡量遠(yuǎn)離大功率設(shè)備，因?yàn)樗旧淼妮敵鲂盘?hào)就比較弱，通常為毫伏級(jí)，極易受到干擾。在這種情況下，將傳感器罩起來(lái)，輸出信號(hào)選擇帶屏蔽的雙絞線(xiàn)纜傳送，其性能會(huì)好一點(diǎn)。線(xiàn)纜鋪設(shè)的時(shí)候還要避免與動(dòng)力電纜平行鋪設(shè)。必須平行放置的時(shí)候，它們之間的距離必須大于50厘米，同時(shí)信號(hào)電纜要用專(zhuān)業(yè)套管進(jìn)行保護(hù)，其屏蔽線(xiàn)纜必須單測(cè)接地且不能和電源線(xiàn)共地。
安裝在室外的稱(chēng)重傳感器要注意防雨防輻射。
對(duì)于已投入時(shí)間很長(zhǎng)的傳感器，可以用加小負(fù)載的方式，檢查它的輸出是否有變動(dòng)，它的運(yùn)動(dòng)部件有可能雜物的影響，導(dǎo)致其輸出精度降低。
Load cell is the most widely used in real life of a sensor, a lot of ordinary people at home can see, today we are concerned that industrial application of the product. Structure of the load cell itself has a solid, long-lasting benefits, but in using the installation process if not careful, it will also affect the performance of the play.
For small measurement sensor, it should be avoided under attack, this will affect its future measurement accuracy. Large measure the product itself is more important important, handling time is best to use a dedicated removal tool, to reach the ground time to slow down, shake it inside to avoid damage to the device, while the base to be installed horizontally, the bottom should be cleaned , can not have debris exist. Any load cell in the course of measuring the need to avoid overloading, which causes the elastic body becomes irreversible, causing permanent damage.
Sensor in the horizontal adjustment process, it is best to use the level meter, making the installation of sensors in a unified horizontal plane, to ensure the consistency of the load they suffered.
Sensor bolt to be used to ensure a certain degree of tightening torque, prolonged use will not become loose.
Sensor is installed as far away from high-power devices, because its own output signal is relatively weak, typically millivolts, vulnerable to interference. In this case, the sensor covers up, choose the output signal transmission with shielded twisted pair cable, its performance will be better. Even when laying cables and power cables to avoid parallel laying. Must be placed in parallel, when the distance between them must be greater than 50 cm, while the signal cable to use professional tube to protect the cable shield must be grounded and not a single measure of ground and power lines.
Load cell installed in the outdoor rain to pay attention to radiation.
For a long time has been put into the sensor, plus a small load can be a way to check whether there are changes in its output, its moving parts may be debris impact, resulting in lower output accuracy.
