METRIX振動(dòng)開(kāi)關(guān)450系列介紹
電子開(kāi)關(guān)采用固態(tài)晶體加速度計(jì)，當(dāng)其因振動(dòng)力而變形時(shí)，會(huì)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(hào)。該信號(hào)與預(yù)設(shè)限值進(jìn)行比較，如果超過(guò)限值，則觸發(fā)固態(tài)繼電器。440 振動(dòng)開(kāi)關(guān)中沒(méi)有移動(dòng)部件，除非配置了機(jī)械繼電器。
開(kāi)關(guān)的一個(gè)重要特性是內(nèi)置延時(shí)。這可以防止因振動(dòng)水平瞬時(shí)增加而觸發(fā)警報(bào)或關(guān)機(jī)功能。它還可以避免因啟動(dòng)期間發(fā)生的瞬時(shí)振動(dòng)而關(guān)機(jī)。
幾乎所有機(jī)器在啟動(dòng)時(shí)都會(huì)經(jīng)歷幾秒鐘的高振動(dòng)，然后才能達(dá)到運(yùn)行速度。當(dāng)沒(méi)有延時(shí)功能時(shí)，就像機(jī)械開(kāi)關(guān)一樣，這種啟動(dòng)振動(dòng)會(huì)導(dǎo)致跳閘。操作員經(jīng)常會(huì)調(diào)高跳閘設(shè)置，直到他能夠完成啟動(dòng)。由此產(chǎn)生的跳閘水平太高，無(wú)法在機(jī)器的運(yùn)行速度下提供保護(hù)。
三秒警報(bào)跳閘延遲是開(kāi)關(guān)的標(biāo)準(zhǔn)配置。警報(bào)時(shí)間延遲可在現(xiàn)場(chǎng)獨(dú)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.
