METRIX振動開關(guān)450系列介紹
電子開關(guān)采用固態(tài)晶體加速度計，當(dāng)其因振動力而變形時，會提供電輸出。輸出以電子方式轉(zhuǎn)換為與速度成比例的信號。該信號與預(yù)設(shè)限值進行比較，如果超過限值，則觸發(fā)固態(tài)繼電器。440 振動開關(guān)中沒有移動部件，除非配置了機械繼電器。
開關(guān)的一個重要特性是內(nèi)置延時。這可以防止因振動水平瞬時增加而觸發(fā)警報或關(guān)機功能。它還可以避免因啟動期間發(fā)生的瞬時振動而關(guān)機。
幾乎所有機器在啟動時都會經(jīng)歷幾秒鐘的高振動，然后才能達到運行速度。當(dāng)沒有延時功能時，就像機械開關(guān)一樣，這種啟動振動會導(dǎo)致跳閘。操作員經(jīng)常會調(diào)高跳閘設(shè)置，直到他能夠完成啟動。由此產(chǎn)生的跳閘水平太高，無法在機器的運行速度下提供保護。
三秒警報跳閘延遲是開關(guān)的標(biāo)準(zhǔn)配置。警報時間延遲可在現(xiàn)場獨立調(diào)整，范圍為 2 到 15 秒。
The electronic switch utilizes a solid state crystal accelerometer which provides an electrical output when it is deformed by the vibration forces. The output is electronically converted to a signal proportional to velocity. This signal is compared with a preset limit and triggers a solid state relay if the limit is exceeded. There are no moving parts in the 440 vibration switches except when configured with mechanical relays.
An important feature of the switch is the built-in time delay. This prevents triggering of the alarm or shutdown functions from transient increases in vibration levels. It also avoids shutdown due to transitory vibrations occurring during start-up.
Almost all machines experience a few seconds of high vibration during start-up before reaching operating speed. When no time delay function is included, as with mechanical switches, this start-up vibration causes a trip. Frequently, the operator turns the trip setting up until he can get through start-up. The resultant trip level is too high to afford protection at the machine’s operating speed.
Three-second alarm trip delay is standard on the switch. Alarm time delays are independently adjustable in the field over a range of 2 to 15 seconds.
