Bently Nevada 330103-00-05-05-02-00接近探头是一款由Bently Nevada公司生产的非接触式传感器产品，广泛应用于振动监测领域。以下是对该产品的详细介绍：

一、产品概述

类型：接近探头（接近传感器）
型号：330103-00-05-05-02-00
品牌：Bently Nevada
应用领域：发电厂、炼油厂、化工厂、钢铁厂、水泵厂、风机厂等行业企业，用于检测汽轮机、水轮机、鼓风机、压缩机、空分机、齿轮箱、水泵等大型旋转机械轴的振动在线测量和保护。

二、技术特点

工作原理：利用转轴表面与传感器探头端部的间隙变化来测量振动，具有零频率响应的特点。当探头顶部的线圈加上高频电流并与一导电表面靠近时，由于线圈磁力线的作用，使导电物体表面产生涡流，从而使线圈的电感量减小。线圈特性的这个变化被转换为直流电压信号输出。
性能参数：

线性范围：根据探头直径不同，线性范围也有所不同，一般可达2mm或4mm。
灵敏度：不同探头直径的灵敏度不同，如7.87V/mm (200mV/mil)或3.94V/mm(100mV/mil)。
频率响应：0-10kHz，从3300 XL 前置器到监测器的最大长度为305米现场联线。
工作温度：标准探头为-52°C至+177°C，高温探头可达-52°C至+218°C。
探头尖端材料：聚苯硫醚 (PPS)

三、系统组成

Bently Nevada 3300XL电涡流传感器系统通常包括探头、延伸电缆和前置器三部分。该型号探头作为系统的一部分，需要与相应的延伸电缆和前置器配合使用，以实现振动监测的功能。

四、安装与应用

安装方式：现场安装，支持X、Y方向两个传感器的安装布局，用于轴振动测量。
支持的振动监测器和模块：如2300/20、1900/65A、3500/42等3500框架系统监测。

Bently Nevada 330103-00-05-05-02-00 proximity probe is a non-contact sensor product produced by Bently Nevada, which is widely used in the field of vibration monitoring. The following is a detailed introduction to the product:

1. Product Overview

Type: Proximity Probe (Proximity Sensor)

Model: 330103-00-05-05-02-00

Brand: Bently Nevada

Application: Power plants, refineries, chemical plants, steel plants, pump plants, fan plants and other industries, used for online measurement and protection of vibration of large rotating mechanical shafts such as steam turbines, water turbines, blowers, compressors, air separators, gear boxes, pumps, etc.

2. Technical Features

Working Principle: Vibration is measured by the gap change between the surface of the rotating shaft and the end of the sensor probe, which has the characteristics of zero frequency response. When the coil at the top of the probe is added with a high-frequency current and is close to a conductive surface, due to the effect of the magnetic lines of force of the coil, eddy currents are generated on the surface of the conductive object, thereby reducing the inductance of the coil. This change in coil characteristics is converted into a DC voltage signal output.

Performance parameters:

Linear range: Depending on the probe diameter, the linear range is also different, generally up to 2mm or 4mm.

Sensitivity: Different probe diameters have different sensitivities, such as 7.87V/mm (200mV/mil) or 3.94V/mm (100mV/mil).

Frequency response: 0-10kHz, the maximum length from the 3300 XL preamplifier to the monitor is 305 meters of field connection.

Operating temperature: Standard probe is -52°C to +177°C, high temperature probe can reach -52°C to +218°C.

Probe tip material: polyphenylene sulfide (PPS)

III. System composition

The Bently Nevada 3300XL eddy current sensor system usually includes three parts: probe, extension cable and preamplifier. As part of the system, this type of probe needs to be used with the corresponding extension cable and preamplifier to achieve the function of vibration monitoring.

IV. Installation and Application

Installation method: On-site installation, supports the installation layout of two sensors in the X and Y directions for shaft vibration measurement.

Supported vibration monitors and modules: such as 2300/20, 1900/65A, 3500/42 and other 3500 frame system monitoring.
