METRIX振動開關450DR-2144-0100技術參數
METRIX振動開關450系列介紹
該電子開關采用固態(tài)晶體加速度計，當其受到振動力作用而發(fā)生形變時，會產生電信號輸出。該輸出信號經電子轉換后，與速度成正比。該信號與預設限值進行比較，若超過限值，則觸發(fā)固態(tài)繼電器。除與機械繼電器配置的情況外，440型振動開關中沒有其他運動部件。
該開關的一項重要特性是內置延時功能。這可以防止因振動水平的瞬時升高而觸發(fā)報警或關機功能。它還可以避免因啟動過程中發(fā)生的瞬時振動而導致關機。
幾乎所有機器在啟動時都會經歷幾秒鐘的劇烈振動，之后才會達到運行速度。如果像機械開關那樣沒有延時功能，這種啟動振動會導致跳閘。通常情況下，操作員會不斷調整跳閘設置，直到能夠完成啟動。但這樣一來，跳閘閾值過高，無法在機器的運行速度下提供足夠的保護。
該開關的標準報警跳閘延遲時間為三秒。報警延遲時間可在現場獨立調節(jié)，調節(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.
