AN3550 series speed monitoring receives signals from a magneto-electric tachometric sensor or Proximity sensor; the original signals from the sensor are converted into digital signals by a signal interface unit; the digital signals are transmitted to 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;l Key-phase signal output.3. Functionsl Highlight digital display unit: To display real-time vibration value;l Plate-type touch keyboard: Field programming parameter setting;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 Buffer interface: Sensor original signal buffer output.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 Embedded microcontroller 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 High/low velocity measuring systems implement precision measurement of zero and low (turning) speed.5. ApplicationApplication 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.
