AN5800/30series speed monitoring module receives signals from two magneto-electric sensors, Magneto-resistive sensors or Proximity sensors; the original signals from the sensor are converted into digitalsignals by a signal interface unit; the digital signals are transmittedto an embedded microcontroller unit (MCU), and are then identified, judged, processed and compared by software and output by output units, thus implementing online monitoring and protection of device Speed.2. Purposesl Online monitoring and protection of rotary machine speed; l Zero-speed survey control;l Over-speed protection.3. Functionsl Digital display unit: To display real-time value;l Serialcommunication interface: Parameter configuration and digital signal buscommunication through AN5800 / CFG configuration software ;l Standard signal output: 4-20mA;l On-off output: two-stage alert normally open/closed contact output;l LED indicator: To display various statuses;l Bufferinterface: The front panel BNC connector and rear terminal buffer output (Sensor original signal) are convenient to connect the data acquisition system to collect dynamic signals.4. Featuresl Perfectself-inspection and diagnosis function; when a failure occurs, current output is 0mA, and "Not Ok" LED on the panel is on;l Embeddedmicrocontroller unit (MCU); an E2PROM data storage unit (for important parameters) and a FLASH process program storage unit are integrated in the chip;l Power unit: a DC-DC/AC-DC module power supply realizes ultra-width power input and isolated output;l Useforward board and back board plug-in module type structure design, after the board (power supply and relay output) and the former board (signal processing, the host) physical isolation, through case motherboard more redundant connectors (needle) in parallel connection, stable and reliable;l High/low velocity measuring systems implement precision measurement of zero and low (turning) speed.5. Application Application Fields:l Power plants (thermal, hydro, nuclear and wind)l Metallurgy (steel mills and aluminium manufacturers, etc.)l Petrochemical engineering (refining and chemical, coal chemical industry and chemical fertilizers, etc.)l Cementl Papermakingl Mine (coal and iron mines)l Hydraulic engineering (reservoirs and pump stations), etc. Monitored equipment:l Steam turbines;l Compressors;l Water pumps;l Water turbines;l Air blowers;l Coal breakers;l Electromotor;l Rotary machines like fans. 6.
