AN5800/50Thermal Expansion monitoring module receives signals from two LVDT sensor; the original signals from the sensor are converted intodigital 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 Thermal Expansion.2. Purposesl Online monitoring of rotary machine Thermal Expansion; l Online monitoring of Valve opening;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 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 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.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 Air blowers;l Rotary machines like Water turbines.6.
