瑞典振動檢測儀 MG4-2A技術(shù)參數(shù) 
瑞典振動檢測儀 MG4-2A技術(shù)參數(shù) Machine Guard MG4-2A is a stand-alone measuring unit for continuous monitoring of machine vibration on two channels. It measures vibration severity (true RMS value of vibration velocity) according to ISO 10816. Machine Guard MG4-2A provides: Twoprogrammablealarmlevelsperchannelandstatus display (green - yellow - red light) Displayofmeasuredvaluewithcontinuousupdates Analogoutputcurrent4-20mAwithprogrammable range or complete data on LAN (Modbus network usingRTU) Relays250V(1)and125V(4)withprogrammable alarm levels. MG4hasacasingforwallmounting,IP65.Itcanbesupplied with mains power or be connected to a PLC. Measuring time, alarm levels, alarm delay and the channel/relay combinations are programmed, using the push buttons on the front panel. It has cable inlets of type M12 for vibration transducers con- nected with twisted pair cables but can be equipped with TNCconnectors(option)forcoaxialcables. Thefollowingoptionsareselectedonorderingtheunit: Power supply: 230Vac,115Vacor15to30Vac/Vdc Vibration channel: Frequencyrange3-1000,3-2000,10-1000,10-2000 or 100-1000 Hz AsanoptiontheMG4canbeequippedwithaRS-485port for sending data via a LAN network. MG4 units equipped for network have no analog outputs.
