Working principle of mechanical vibration transmitter

HZD-B-8BIntegrated vibration transmitter

1、 Introduction

HZD-B-8BIntegrated vibration transmitter is an on-site transmitter used for real-time online monitoring of bearing vibration in rotating machinery. Installed on the bearing seat or casing of the machine for real-time online monitoring. If the machine equipment malfunctions due to factors such as bearing wear, bearing cracking, or incorrect dynamic balance during operation, the integrated vibration transmitter can detect the fault in advance and issue an alarm to prevent the machine from continuing to work under adverse conditions and causing damage. Simultaneously integrated vibration transmitter with direct output4-20mACurrent signal, directly connectedPLCTheDCSDigital display instrument, recorder, collector or other monitoring equipment.

2、 Application Fields

Seven working principles:

Integrating the magneto electric speed sensor and precision measurement circuit together has achieved the traditional "sensor+The function of the "transmitter" mode vibration measurement system is suitable for building an economical high-precision vibration measurement system, and the transmitter can be directly connectedDCSThePLCOr other systems, it is an ideal choice for vibration measurement of factory equipment such as fans and pumps.

Built in sensors sense vibration speed and convert mechanical vibrations into corresponding ranges through high-precision integrated circuits4～20mACurrent output, which can be directly connected toPLC/DCSOr other receivers4-20mASignal equipment connection, such as our company'sLH6000Monitoring system orLH6080Display the alarm device. Mainly used to monitor the vibration of rotating machinery, such as casing vibration, bearing vibration, frame vibration, etc.

8、 Application scope:

Unit type: various rotating machinery. Such as fans, compressors, motors, pumps, gearboxes, water turbines, etc.

9、 Easy installation:

Installation requirements for the probe: only need to make a φ on the casing35mmThe platform, openM10×1.5Screw hole, fix the probe on the screw hole without any operation inside the machine.
