Product Details JM-B-7 Intelligent Vibration Monitoring and Protection Device for 600 to 60 000 rpm / min and the displacement of rotating machinery vibration severity of long-term monitoring, and magnetic vibration speed sensor package, you can monitor the vertical rotating machinery, horizontal vibration direction, vibration size is determined by the instrument front panel display, while a standard analog current output can be used with a variety of DCS, PLC system is connected with, when the vibration value exceeded, the instrument can be an external audible alarm to alert on-site operation officers to take preventive measures, and there are two alarm switch output, protect the machine safe and reliable operation. Function l intelligent treatment: the value of the alarm Ⅰ, Ⅱ value can be set by panel keys l panel buttons adjust the scale value, no potentiometer adjustments to facilitate on-site commissioning l one minute does not press the action button, you can return to running their own l alarm delay adjustment range from 1 to 60 seconds, in order to prevent false alarms caused by interference field l has a power-down detection, sensor detection dropped, cut off the alarm, stop the output circuit, can effectively suppress false alarms instrument l vibration intensity (vibration intensity) and the vibration displacement (vibration amplitude) manual switching. Technical indicators l Frequency range: 10 ~ 1000Hz l Range: 0 ~ 50.0mm / s or 0-500um (adjustable) l Accuracy: ± 1% (full scale) l Current output: 4 ~ 20mA l switch output: DC 30V / 5A or AC250V / 5A (normally open) l alarm settings: full scale arbitrarily set l Temperature: Operating: 0 ~ 65 ℃ Storage time: -30 ~ 80 ℃ l Relative Humidity: 95%, not condensing l Power supply voltage: 220VAC / 50Hz ± 10% 50mA l Dimensions: 160 × 80 × 160mm hole size l: 152 + 1 × 74 + 1mm
