PR6424/011-140  EPRO振动探头

产品概述

PR6424/011-140 是德国EPRO公司生产的一款高性能涡流式振动传感器。它主要用于测量旋转机械设备轴系的振动，通过检测轴与传感器之间的相对位移，将振动信号转换为电信号，从而实现对设备振动状态的实时监测。

产品特点

高精度: 采用先进的涡流测量技术，具有极高的测量精度，能够准确检测微小的振动信号。

耐高温: 能够在恶劣的工业环境下长时间稳定工作，耐高温性能优异。

抗干扰能力强: 不受磁场、油污等环境因素的影响，具有较强的抗干扰能力。

安装方便: 安装方式灵活，易于集成到现有系统中。

信号输出多样: 可以提供多种类型的输出信号，如模拟信号、数字信号等，方便与其他设备连接。

工作原理

涡流传感器的工作原理是基于电磁感应。当传感器靠近导电体（如旋转轴）时，传感器线圈产生的交变磁场会在导电体中感应出涡流。涡流的大小和相位与导电体与传感器的相对距离有关。通过测量涡流的变化，可以得到振动信号。

Product overview

PR6424/011-140 is a high performance eddy current vibration sensor manufactured by EPRO. It is mainly used to measure the vibration of rotating mechanical equipment shafting, by detecting the relative displacement between the shaft and the sensor, the vibration signal is converted into an electrical signal, so as to realize the real-time monitoring of the vibration state of the equipment.

Product characteristics

High precision: The use of advanced eddy current measurement technology, with extremely high measurement accuracy, can accurately detect small vibration signals.

High temperature resistance: It can work stably in harsh industrial environment for a long time and has excellent high temperature resistance.

Strong anti-interference ability: it is not affected by environmental factors such as magnetic field and oil pollution, and has strong anti-interference ability.

Easy installation: Flexible installation and easy integration into existing systems.

Various signal output: can provide a variety of types of output signals, such as analog signals, digital signals, etc., easy to connect with other devices.

Working principle

The working principle of the eddy current sensor is based on electromagnetic induction. When the sensor is close to the conductor (such as the axis of rotation), the alternating magnetic field generated by the sensor coil induces eddy currents in the conductor. The size and phase of the vortex are related to the relative distance between the conductor and the sensor. The vibration signal can be obtained by measuring the change of eddy current.

Application field

Power plant: Monitor the vibration state of turbine, generator, pump and other equipment.

Petrochemical: Monitoring the vibration state of compressors, pumps, valves and other equipment.

Iron and steel metallurgy: Monitoring the vibration state of rolling mills, motors and other equipment.
