PLF-BIII-EX電子振動開關(guān)可以連續(xù)監(jiān)測離心機機器的振動。如果機器的振動超過允許值，將提供報警或關(guān)閉機器電源，保護機器不受損傷。在大多數(shù)情況下，振動可以在機器損壞前的相當(dāng)長時間內(nèi)體現(xiàn)機器的問題。例如，振動監(jiān)測可以比溫度監(jiān)測早得多的探測出機器的可能出現(xiàn)的故障。PLF-BIII-EX主要監(jiān)測以下主要的機器故障種類:轉(zhuǎn)子不平衡、不對中、軸承損壞、皮帶損壞。

The PLF-BIII-EX electronic vibration switch can continuously monitor the vibration of the centrifuge machine. If the vibration of the machine exceeds the allowable value, it will provide an alarm or shut off the machine power to protect the machine from damage. In most cases, the vibration can reveal the problems of the machine before it causes damage. For example, vibration monitoring can detect possible machine failures much earlier than temperature monitoring. The PLF-BIII-EX mainly monitors the following main types of machine failures: rotor imbalance, misalignment, bearing damage, and belt damage.

Technical parameters of PLF-BIII-EX electronic vibration switch

Function Description:

Using integrated professional electronic circuits, the entire system has no mechanical components.

Installation is simple; only three screws are needed for fixation.

Relay alarm provides a normally open contact output. It can be connected to PLC, DCS, for on-site control of relays or directly control rotating machinery with 4-20mA active output, and directly drive the display.

Internal digital display, facilitating user inspection

Explosion-proof and environmental protection, with a fully enclosed aluminum casing.

The reliability is much higher than that of mechanical vibration switches.
