浏览次数:22PLF-BIII-EX电子振动开关可以连续监测离心机机器的振动。如果机器的振动超过允许值,将提供报警或关闭机器电源,保护机器不受损伤。在大多数情况下,振动可以在机器损坏前的相当长时间内体现机器的问题。例如,振动监测可以比温度监测早得多的探测出机器的可能出现的故障。PLF-BIII-EX主要监测以下主要的机器故障种类:转子不平衡、不对中、轴承损坏、皮带损坏。

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.
