CZJ-B SeriesVibration Monitor
CZJ-B SeriesVibration Monitor Operation Manual
1．GeneralCZJ-B is a kind of indispensable test and protection deviceused for rotating machinery equipment such as fan, compressor andsteam turbine generator, etc. It can match with SZ series speedtransducer to continuously monitoring and measuring the absolutevibration peak – peak value or the vibration speed of bearings inall kinds of rotating machinery. There is current output which isdirect proportion with the measure value. It can directly connect toDCS, PLC System and the non-paper recorder. When vibration is overlimit value, it can provide automatically the alarm relay switchvolume contact point output.This product has high precision, stable performance, stronganti-interference and high reliability. It is widely used for power,machinery, chemical industry and metallurgic industry, etc., andsuitable for the monitor system design for small and middle scalerotating machinery device. There are pan fixed type and wall hangedtype for customer’s option in this CZJ-B series vibration monitors.This monitor can match with the model SZ-6i local installed typeelectromagnetic speed transducer so as to be used in the explosionproof site. The explosion proof site certificate No. is CNEx09.2137Uand the explosion proof mark is Exib II BT4.2．ProductsCZJ-B2 Vibration Intensity MonitorCZJ-B3 Vibration Intensity MonitorCZJ-B3G Vibration Intensity Monitor （Wall hanged meter）CZJ-B4 Vibration MonitorCZJ-B4G Vibration Monitor（Wall hanged meter）
