Jiangyin Zhonghe Electrical Power Instrument Co., Ltd.



1、 Overview
HM2012B Vibration Monitor is a double-channel instrument (hereinafter referred to asHM2012B). It can receive two-channel signals at the same time, which is from two magnetoelectricvelocity sensors. and it also can be used for continuously monitoring and measuring absolutevibration peak-peak value or vibration speed average value (intensity) of various rotary bearings.The monitor is provided with (4～20) mA current output which is corresponds to vibratorymeasuring range or intensity measuring range. The LED lamps are used to indicate the ultralimitalarm, the ultralimit alarm have corresponding relay switching signal output.The monitor uses common MODBUS-RTU communication protocol and the standard RS485communication interface. The parameters and the working mode of the monitor can be set andconfigured on LCD. The meter can monitor vibration amplitude and vibration speed, but one of themneeds to be set as main parameter. After setting the main parameter, both alarm and (4 - 20) mAcurrent output of the monitor are corresponding to main parameter.The monitor can be used in inflammable and explosive environment when it matches with SZ-6iintrinsic safety type Magnetoelectric Velocity Sensor. The explosion-proof level of intrinsic safety isExia ⅡC T6 Ga.DCS、PLC and PC can achieve remote communication and monitoring with the monitor easily.It is widely used in the industry of power, fan, steel, petrochemical, etc.
2、 Application It is suitable for the monitoring and protection of rotating machineries’ bearing vibration, such as steam turbine, water turbine, generator, fan, pump and so on.
