YD420 Dual-channel widescreen axial vibration monitoring

1. Brief Introduction

YD420 Dual-channel axial vibration monitor with DSP system installed,is precision 

intelligent measurement and control instrument, widely used in electric power,petroleum, chemical and other departments.Through the magnetic-electric sensor the instrument can continuously monitor and  measure the peak-peak value for the vibration of the steam turbine, wind  turbine and other rotating machine.With alarm and shutdown control signal output, equipped with current

output and RS485 interface, it can connect with computers and other devices and synchronize 

with PLC equipments.

The Monitor uses an 80 × 160 (mm) common chassis,LED digital display,PVC color mask and light touch keys,it has a European standard resolution of 128*64 on the display with beautiful appearance, novel style,reasonable structure, simple installation, stable performance and reliable quality.

 

2. Main Functions 

 

1.1 it has two channels, each channel can measure and display the vibration amplitude.

1.2 It has 4 dual channel switching control the signals. Using a miniature high-power relay,  the maximum switch voltage is 440VAC / 125VDC, the maximum switch current is 16A, the maximum switch power is 4000VA, mechanical pressure resistance is 10million times. Through the lower limit alarm value setting, the upper limit alarm value setting, the alarm delay setting and the lower limit danger value setting, the upper limit danger value setting, the danger delay setting, relevant action, when the vibration amplitude reaches a preset value, the relay switch enter into working state.

1.3 Multifunction digital keyboard. In the main display interface, press "1" enter 1 channel information display; press "2" enter 2 channel information display; press "3" enter the dual channel display simultaneously; press "M" enter the menu item; press "↑↓" direction keys to change the different display information in the channels; press "." to return.

1.4 Dual 4 ~ 20mA isolation high precision current transmission output, with high precision voltage reference inside, 18 digits precision voltage drive chip, high precision and low drift operational 

amplifier, guarantee the accuracy of the output reach 0.01%. By the main range lower limit setting and main range upper limit setting of the menu item, divide it into the corresponding current interval of 4 ~ 20mA accurately, so that improves the accuracy of output signal. Calibrate the lower limit and upper limit of current loop by current meter, then demarcate the linearity of 4 ~ 20mA more accurate.

1.5 The device has main range display, percentage display, bar graph display, transmission current display. It is more convenient, fast and accurate for customers to do calibration in the site application.
