YD420 Dual Channel Vibrating Monitor

Brief Introduction

YD420 intelligent shaft vibration monitor is a precision intelligent measurement and control instruments, widely used in electric power, petroleum, chemical and other departments. Through eddy current sensor, the instrument can continuously monitor and measure the axis vibration of turbine, fan and other rotating machine. It has alarm and shutdown control signal output, equipped with current output and RS485 interfaces, the instrument can connect with computers and other devices. The Monitor uses an 80×160×205 (mm) 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.

Main Function

2.1 With two channels, each channel can measure and display 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 panel 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.
