YD430 vibration monitoring systems

1.Brief Introduction

YD430 vibration monitor is a precision intelligent measurement   and    control instruments, widely used in electric power, petroleum, chemical and other departments. Through the magnetic-electric sensors 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 interfaces. It can connect with computers and other devices. The Monitor uses an 80 × 160 (mm) common chassis,  LED digital display, PVC color mask and light touch keys, and it has beautiful appearance, novel style, reasonable structure, simple installation, stable performance and reliable quality.

2.Main Functions

2.1 With two channels, each channel can measure and display the vibration amplitude.

2.2 With alarm protection function, when vibration amplitude exceed alarm set value, the alarm indicator light will on, and meanwhile output on/off signal at the rear of the panel to protect the monitored equipment.

2.3 User can arbitrarily set by pushing any buttons in the    front of    the   pane  l if two   level alarm setting value is in the measuring range.

2.4 With current output and RS485 interfaces which can connect with computers and other devices.
