Overview
The dual channel reverse protection monitoring instrument $r $n for industrial water pumps and other rotating machinery is not allowed to have reverse rotation. When reverse rotation occurs, immediate measures should be taken. The DF9814 reverse protection monitor is specifically designed for this purpose. It is equipped with two sets of eddy current sensors and installed at the required angle to monitor equipment speed and measure shaft rotation direction. It also provides alarm and protection signals when the equipment reverses.
Product Details
Dual channel reverse protection monitoring instrument
DN/DF9814Wall mounted programmable reverse protection monitoring instrument isDF9000Durable and sturdy series of programmable monitoring instruments.DN/DF9814The wall mounted programmable monitoring instrument adopts a fully sealed cast aluminum shell and waterproof joint, which can be installed without the need for a protective box. It can be directly applied in humid, dusty, and high and low temperature environments, especially suitable for rotating mechanical equipment (fans) working outdoors and other harsh environments/Monitoring and protection of the status of water pumps, etc.
DN/DF9814Wall mounted programmable reverse protection monitor can receive two channelsDN/DF3100/DN/DF5100Eddy current sensor speedSignal,Continuous measurement and monitoringThe speed and direction of rotation of the machine, and provide overspeed and reverse protection for the equipment.
Speed signalAfter instrument signal processing, it is converted to meet the user's needsThe rotational speed valueOutput, display on the panel, and convert to4～20mACurrent remote transmission signal, the instrument also providestwo levelsAlarm andReverse protectionSwitching output, all parameter settings can be achieved throughDF9000Configuration software is used to complete the configurationParameters and data are stored inE2PROMInternally, it can be stored for a long time in case of power loss.
DF9814The wall mounted reverse protection monitoring device does not require a protective box during installation, and can be directly applied in humid, dusty, and high/low temperature environments, especially suitable for monitoring and protecting the status of rotating machinery equipment working outdoors and other harsh environments.
