GZW25-120 Industrial Vibration Sensor

GZW25-120 Industrial Vibration Sensor

1、 Product Overview

An integrated vibration transmitter that integrates a magneto electric speed sensor and precision measurement circuit, capable of directly outputting standard signals corresponding to the vibration quantity. Its core function is to monitor the vibration intensity (velocity effective value) of rotating machinery and provide continuous 4-20mA current signal output, making it easy to connect to control systems such as DCS and PLC. This product is made of 304 stainless steel material and has good environmental adaptability.

3、 Explanation on Vibration Oil Level Monitoring

It should be noted that the main function of HZD-B-8B-A4 vibration sensor is to monitor mechanical vibration. In its standard function, the oil level monitoring function is not directly integrated. This sensor is mainly used to measure the vibration of parts such as the casing and bearing seat.

If your application scenario requires simultaneous monitoring of vibration and oil level, the usual solution is to additionally configure independent oil level sensors or specialized multi parameter monitoring instruments for the system, working in conjunction with HZD-B-8B-A4.

4、 Installation and wiring requirements

1. Installation position: Choose a position that can truly transmit rotor vibration to the bearing box or casing. The installation surface should be flat, and it is recommended to install it horizontally or vertically.

2. Installation method: Prepare a platform with a diameter of 35mm on the casing, open M10 × 1.5 screw holes, and tighten the sensor clockwise to ensure a tight fit between the bottom and the casing.

3. Wiring specifications:

·Use shielded cables for connection.

·The shielding layer should be grounded at a single point at the DCS/PLC end (control system end) and not at the sensor end.

·When wiring, avoid parallel connection with strong interfering power lines and control cables.

4. Safe operation: It is strictly prohibited to carry out disassembly or wiring operations while live.

5、 Typical applications

This sensor is an ideal choice for vibration monitoring of the following types of rotating machinery:

·Power equipment: fan, compressor, steam turbine, water turbine

·Fluid machinery: water pump, air compressor

·Power unit: motor, generator

·Transmission equipment: gearbox

6、 Troubleshooting tips

If there is measurement drift or instability, you can check in sequence:

1. Are all mechanical connection parts securely fastened.

2. Check if the sensor installation is loose.

3. Are all electrical connections secure.

4. Whether the grounding of the shielding layer is reliable.

5. Is there any abnormal heat source around the sensor that causes it to exceed the operating temperature range.
