METRIX振動(dòng)開關(guān)450系列介紹
該電子開關(guān)采用固態(tài)晶體加速度計(jì)，當(dāng)其受到振動(dòng)力作用而發(fā)生形變時(shí)，會產(chǎn)生電信號輸出。該輸出信號經(jīng)電子轉(zhuǎn)換后，與速度成正比。該信號與預(yù)設(shè)限值進(jìn)行比較，若超過限值，則觸發(fā)固態(tài)繼電器。除與機(jī)械繼電器配置的情況外，440型振動(dòng)開關(guān)中沒有其他運(yùn)動(dòng)部件。
該開關(guān)的一項(xiàng)重要特性是內(nèi)置延時(shí)功能。這可以防止因振動(dòng)水平的瞬時(shí)升高而觸發(fā)報(bào)警或關(guān)機(jī)功能。它還可以避免因啟動(dòng)過程中發(fā)生的瞬時(shí)振動(dòng)而導(dǎo)致關(guān)機(jī)。
幾乎所有機(jī)器在啟動(dòng)時(shí)都會經(jīng)歷幾秒鐘的劇烈振動(dòng)，之后才會達(dá)到運(yùn)行速度。如果像機(jī)械開關(guān)那樣沒有延時(shí)功能，這種啟動(dòng)振動(dòng)會導(dǎo)致跳閘。通常情況下，操作員會不斷調(diào)整跳閘設(shè)置，直到能夠完成啟動(dòng)。但這樣一來，跳閘閾值過高，無法在機(jī)器的運(yùn)行速度下提供足夠的保護(hù)。
該開關(guān)的標(biāo)準(zhǔn)報(bào)警跳閘延遲時(shí)間為三秒。報(bào)警延遲時(shí)間可在現(xiàn)場獨(dú)立調(diào)節(jié)，調(diào)節(jié)范圍為 2 至 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.
