HZD-B-X vibration transmitter

I. Overview

HZD-B-XThe vibration transmitter with display is an addition to the integrated vibration transmitterLEDLCD display screen, displaying the effective value of vibration velocity or peak to peak value of vibration displacement through the LCD screen, and with standard4-20Milliampere current output,Direct connectionDCSThePLCOr other devices that truly achieve the "sensor ten monitoring instrument" type vibration monitoring function, this product is easy to observe on site, has excellent performance, and is relatively affordable compared to vibration monitoring instruments. It is an ideal choice for factory equipment vibration measurement and monitoring.

The split vibration transmitter is paired with a vibration velocity sensor to measure the vibration of rotating mechanical bearings and output current signals. It can be used with computersDCSThePLCsystem,Connect devices such as paperless recorders.

Fault monitoring: Monitor the vibration of rotating machinery, such as casing vibration, bearing vibration, frame vibration, etc; Monitor the increase in vibration caused by rotor imbalance, misalignment, loose components, damaged rolling bearings, gear damage, etc.
Measurement parameters: displacement, velocity.
Unit type: Monitoring of vibration in small and medium-sized units, such as steam turbines, fans, compressors, motors, pumps, gearboxes, etc; Especially suitable for the renovation of old units.
Installation requirements: Only one screw hole needs to be drilled on the casing to fix the sensor on the double headed screw, without any operation inside the machine.

3、 Installation method

Fix the sensor at the measurement position of the device, install the transmitter on the guide rail of the control cabinet, and connect the two signal wires of the sensor to the "+" and "-" terminals of the transmitter signal respectively (the two wires of magneto electric vibration velocity are not positive or negative). Connect the 4-20mA signal to the DCS/PLC system. POWER (+) is connected to the positive pole of the power supply, and POWER (-) is connected to the negative pole of the power supply. After the connection is made and checked for accuracy, power can be turned on.Installation of guide rails or base plates.

1、 Introduction

HZD-B-XThe vibration transmitter adopts an intelligent vibration transmitter with a microcontroller as the core, which adds a digital display function, makes the measurement data more intuitive, and the parameter setting more convenient. It is matched with a vibration speed sensor and mainly used to detect the vibration of rotating machinery, such as casing vibration, bearing vibration, mechanical vibration, etc; Monitor vibration changes caused by rotor imbalance, misalignment, loose components, damaged rolling bearings, gearbox damage, etc. Suitable for large rotating mechanical equipment such as steam turbines, water turbines, fans, compressors, oxygen concentrators, motors, pumps, gearboxes, etc., especially suitable for retrofitting old units.

2、 Main application areas:

Monitoring and protection of bearing vibration in rotating machinery such as steam turbines, motors, coal mills, fans, reducers, water pumps, centrifuges, balancing machines, and air compressors.

3、 Function Description:

Realize intelligent processing: Alarm values can be set arbitrarily through panel buttons

The panel buttons can adjust the range value without the need for potentiometer adjustment, making it convenient for on-site debugging

If you don't press the operation key for one minute, you can return to the running state by yourself

Alarm delay adjustment range1~60Seconds to prevent false alarms caused by on-site interference

There are current output terminals on the back panel that are proportional to the amplitude of the vibration, which can be connected to computersDCSThePLCConnection of devices such as systems and paperless recorders

Vibration displacement and vibration intensity can be freely switched
