HZD-L vibration intensity monitor is mainly used for long-term monitoring of the vibration intensity of rotating machinery with speed of 600~6000 rpm. It is matched with ST series magneto-electric vibration speed sensor and can monitor the vertical and horizontal vibration of rotating machinery. The vibration intensity value is displayed by the head of the instrument front panel, and has a standard current output. It can be connected with various DCS and PLC systems. When the vibration value exceeds the limit, the instrument can be connected with an external sound and light alarm to prompt the operation. Personnel take precautionary measures and have alarm and dangerous switch output to protect the machine safely and reliably. I. Overview
The HZD-L/W vibration monitor can be connected to a variety of vibration sensors, such as magneto-electric speed sensors or eddy current sensors. When connected to the speed sensor, it can measure the vibration intensity (vibration speed RMS) or displacement (vibration amplitude) in the vertical or horizontal direction of the casing or housing.
When connected to an eddy current sensor, the radial and horizontal radial vibrations of the rotating machine shaft can be measured. The digital display can separately display the vibration values ​​of the two channels. Each channel has an independent alarm, hazardous circuit and relay contact output. Accurately set alarm and hazard values, alarms and dangerous delay times, and view alarm and hazard settings at any time.
The standard voltage (1~5V) or standard current (4~20mA) corresponding to the vibration value can be independently output for use by a computer, data collector, recorder or other automatic control system. Other voltages or currents can also be output as needed. The gain of each channel is automatically adjusted for easy calibration of the system.
All functions are controlled by a single computer, and the parameter settings are all completed by the buttons. The adjustment is convenient, the precision is high, stable and reliable.

It can measure the vibration of the casing or structure relative to the free space, that is, the absolute vibration. It is especially suitable for machines with ball bearings. In this machine, the vibration of the shaft can be transmitted to the casing more, so the monitor can be equipped with Connect the magnetic speed sensor to continuously measure and protect the rotating machine. The sensor should be installed with special care, without causing the sensor amplitude to be reduced, and the frequency influence is changed or the generated signal can not represent the real vibration of the machine. For the motor, Compressors, fans, etc. need to measure a large number of vibration points, and the monitor is especially suitable.
The main function realizes intelligent processing: alarm I value, II value can be adjusted by panel button to adjust the range value, no potentiometer adjustment, convenient on-site debugging
30 seconds without pressing the operation button, you can return to the running state. The rear panel has a current output terminal proportional to the vibration amplitude value. The recording output has an alarm delay function (any setting is 0~25.5 seconds).

The S(afe)-LOCK safety lock is adhesive-free and has a snap-type gasket connection structure. It is firmly fixed and easy to inspect and maintain. It has an adhesive-free function throughout its life cycle.
The semi-closed gasket groove design technology solves the problem of sealing elasticity release and sealing reliability of the gasket under harsh working conditions such as high pressure and alternating working conditions; at the same time, it effectively isolates the gasket from contact with the atmosphere and media, thereby reducing the gasket's The aging of the gasket is ensured and the service life of the gasket is extended.
The large plate corner holes and the semi-gasket positioning structure design of the secondary sealing area greatly improve the pressure-bearing performance and sealing performance.
Operational safety protection technology, the gasket has four leakage inspection holes at the second seal that are connected to the atmosphere, which can detect medium leakage and reflect the safety protection of stable operation of the equipment.
